This time he came to Liushugou mainly to solve the problem of seamless steel pipes for the mortar project of the arsenal. He had originally planned to build a cross-rolling mill, and Yu Hua's idea coincided with his.
"Yes, yes...Professor Zhuang, I will take you there, please follow me." Zhao Shu reacted immediately and realized what this moment meant. He was a little incoherent and showed excitement, so he answered quickly.
Not only Zhao Shu, but section chiefs Hu Zhigang and Zhao Zhangcheng were equally excited. After all, the two-roller cross-rolling mill was built to produce mortars.
But that's not the point.
The important thing is that they can make their own two-roll cross-rolling mill, the core equipment for producing seamless steel pipes!
When things had developed to this point, there was no need to go to the arsenal for the time being. The group quickly rushed to the sand foundry workshop of the iron plant. Next, Zhuang Qianding and Yu Hua quickly constructed the design drawings of the two-roller cross-rolling mill and initially determined the size and shape of the rolls and mandrels.
.
The core rod has a diameter of 60 mm, a length of 1 meter, a cylinder, and a theoretical weight of 21 kilograms.
The roller has a diameter of 180 mm, a length of 1 meter, a cylinder, and a theoretical weight of 190 kg.
This is a two-roll cross-rolling machine with a net weight of about 500 kilograms. It has no flat outer shell packaging, no electronic equipment, no various precision measuring instruments and control systems. It only has a mechanical structure composed of two rollers and a mandrel. It is extremely simple.
The entire two-roller cross-rolling mill is driven by a high-power DC motor, which amplifies the torque through the transmission system and applies a maximum rolling force of 300KN.
After finalizing the design plan, Zhuang Qianding, accompanied by Hu Zhigang and Zhao Zhangcheng, the chiefs of the ordnance industry department, rushed to the arsenal and prepared to use the arsenal's ordinary vehicles to open molds.
Yu Hua stayed at the iron factory to witness the official opening of the first blast furnace in the Shaanxi-Gansu-Ningxia Border Region for ironmaking.
…
Escalators were built at the feed inlets on the left and right sides of the blast furnace. The former director, Ma Tian, and a Red Army soldier were carrying full wooden barrels. One barrel contained sintered iron ore as big as glass beads, and the other one contained
It is coke, which is poured into the funnel-shaped feed port in an orderly manner.
Steam is rising at the feed inlet, and fine coal powder and diesel fuel burn violently, and then a steady stream of heat is released under the action of the blower, igniting coke and sinter.
One barrel after another, factory director Martin and the soldiers poured barrels of raw materials into the blast furnace like tireless machines.
Apart from anything else, the conveyor belt must be clicked out immediately. - Yu Hua looked at the blast furnace charging process. Director Ma Tian and the soldiers on the escalator were exhausted and sighed softly.
The entire manual loading process is slow, laborious, and extremely inefficient.
Two tons of pig iron, according to the smelting level of the indigenous blast furnace, requires at least four and a half tons of sinter and one ton of coke. These smelting raw materials are all put into the blast furnace manually. How much time does it take?
"What's wrong?" Sensing something strange about Yu Hua, Lin Wan, who was holding a notebook and pencil to record information, turned around and asked with concern.
"We should manufacture conveyor belt equipment as soon as possible, otherwise, we can't accomplish great things by relying on manpower alone." Yu Hua stared at the sweaty factory director Ma Tian and the Red Army soldiers, and said softly.
He admired the factory director Martin who took the lead in loading the materials himself, but in terms of the efficiency and time of manual loading, it was far inferior to the power of machinery.
Conveyor belt is a kind of mechanical equipment that transports materials in a systematic and highly automated manner. Even though it is ordinary, it may not seem like a big deal. In fact, it is one of the greatest inventions in the history of human civilization. The reason why modern industry can be so developed is
Conveyor belt equipment should account for at least three-thirds of the credit.
With its ultra-high conveying efficiency and extremely simple principle structure, in terms of conveying materials alone, the conveyor belt equipment can completely outperform transportation vehicles such as trains and ships.
"It is true that manual loading is time-consuming and laborious, but I don't know much about conveyor belt equipment. For the time being, I can only help you get started and learn through practice." Lin Wan heard this and nodded, expressing her support. She knew about the conveyor belt equipment.
importance, but due to limited academic level and knowledge reserve, I don’t know much about the mechanical structure and principles of conveyor belts, so I can’t share the research and development work for Yu Hua.
Of course, there is no problem in being a helper. After all, she is also a top student admitted to Peking University.
"It's enough if you can strike. Come on, Jinyu." Hearing this, Yu Hua smiled slightly and stretched out his right hand.
"Come on, Yu Hua."
Lin Wan smiled and nodded, raising her right hand.
"Pa!" The two right hands slapped each other to express the most sincere blessings.
The charging of the blast furnace continued. After an hour, director Martin and the Red Army soldiers reached their physiological limits and had to be replaced to continue loading and delivering raw materials.
A total of 11,000 kilograms of iron ore and coke took two hours to process.
After all the raw materials are loaded, the feed port is closed.
The high-power blower arranged under the blast furnace operates at full capacity. The coke, which is the main heat source, burns violently and releases a high amount of heat. The temperature inside the blast furnace quickly rises to about 1,450 degrees Celsius. The iron ore, which is already in a softened state, is heated at high temperatures.
It gradually melts after reacting with limestone to form orange-red molten iron, with a layer of liquid slag gradually floating on the surface.
The reaction process inside the entire blast furnace is very complex.
As time slowly passes, more and more iron ore is melted into molten iron, forming a molten pool below the blast furnace.
Outside the blast furnace, harmful exhaust gas containing various substances continued to emit from the top exhaust vent, floating into the blue sky, polluting the surrounding air. Standing at a safe distance, Yu Hua, smelling the smell coming from the steel industry, felt sleepy.
Feeling relaxed and happy.
This taste is very good.
When the smelting process was one-third complete, guard Xiao Li and two soldiers rushed over, carrying the newly smelted ferrosilicon inoculant.
Immediately afterwards, Professor Zhuang and his team appeared one after another. Hu Zhigang was holding a cylindrical roller standard mold, and Zhao Zhangcheng was holding a 60mm mandrel standard mold that was like a gun barrel. The molds were all made of elm wood, which saves time and effort.
The mold and ferrosilicon are in place and everything is ready.
The skilled workers in the sand foundry workshop of the iron factory are making sand molds for rolls and mandrels as quickly as possible. These skilled workers are all from the arsenal workers before the Long March. They have worked in major factories in the Republic of China and are skilled and experienced.
Although they don't know much about mechanical principles and mathematical calculations, they have extremely rich front-line practical experience. They are extremely familiar with sand casting and pouring molds. If it were left to Japan, there would be a sand casting immortal.
Before the first blast furnace of Liushugou Iron Works produced molten iron, the sand molds for four rollers and two 60mm mandrels were successfully prepared and transported to the blast furnace to wait for the molten iron.
As time passed by, more and more people gathered around the blast furnace of the iron factory. Chen Kang, the top technical team, heads of departments of the Military Industry Bureau, heads of major factories, and General Liu who came after hearing the news.
Man, the battle is not a big one.
This is the first furnace of molten iron in the base area. It is of great significance and everyone is here to witness it.
At 10:30 in the evening, it was time to officially tap the molten iron.
Below the blast furnace, four workers carried a crucible capable of holding 150 kilograms of molten iron like a sedan to the taphole and waited. There were three such teams behind them.
At this moment, everyone is paying attention.
When the first group of foundry teams was ready, an old worker came to the taphole below the blast furnace and used a steel drill to open the mud seal. In an instant, orange-red molten iron like magma suddenly gushes out and enters everyone's sight.
The groove flows down into the crucible below.
"Bah, bang, bang!" Seeing the orange-red molten iron flowing into the crucible, everyone at the scene applauded and applauded in unison.
There is no doubt that this is a historic moment, symbolizing the base area's restoration of pig iron production capacity.
Not long after, the first pot of molten iron was filled. Four casters carefully lifted the 150 kilograms of molten iron out of the blast furnace and headed for the pouring area. The second group of casters caught up and tried not to waste any drop of molten iron.
When they came to the pouring area, the first group of casters picked out the slag floating on the surface, and then the factory director Ma Tian, who was standing aside, dropped a portion of powdered ferrosilicon into the molten iron in the crucible according to the prearranged arrangement, and carried out the incubation process to create artificial iron.
Crystal nucleus.
This was a standard ratio accurately calculated by Yu Hua. Although Martin didn't know why he put in ferrosilicon, he still carried out the order.
After stirring, in the microscopic world, the high-temperature molten iron reacts under the action of ferrosilicon, producing fine artificial crystal nuclei and precipitating graphite.
After adding the inoculant, the factory director Martin retreated to a safe distance, and the first group of four casters tilted the crucible mouth, aimed it at the water inlet of the mandrel sand mold, and poured out the molten iron.
"Squeak!" The fiery red molten iron was like a faucet, continuously flowing into the mandrel sand mold. In an instant, the sand mold made a sound like frying, and flames burst out from inside.
Fortunately, no explosion occurred.
After the first mandrel sand mold was poured, the second mandrel was poured immediately. The two mandrels were not heavy, adding up to more than 40 kilograms. The remaining about 100 kilograms of molten iron in the first pot were used to pour the roller sand mold.
The four roller sand molds are among the largest consumers of molten iron, requiring a total of more than 800 kilograms of molten iron.
Under everyone's gaze, four teams of casters worked back and forth, pouring hot molten iron added with ferrosilicon into the roller sand mold.
After more than twenty minutes, all the roller sand molds were poured, and next came the most important cooling and solidification stage of smelting gray cast iron.
To obtain gray cast iron, the first is the inoculant, and the second is the cooling time. The temperature cannot drop too fast during the cooling and solidification stage, otherwise graphite cannot be precipitated.
If necessary, the casting needs to be taken out of the sand mold and placed in a hot sand pit with a temperature above 500 degrees Celsius, or slowly cooled near a hot furnace.
Yu Hua and Lin Wan entered the pouring area, surrounded the six sand molds, and carefully recorded data such as pouring time and pouring performance.
"The mandrel cooling time is one and a half hours, and the roll cooling time is five and a half hours. At this time, the mold can be demolded. Jin Yu, please record it." After Lin Wan finished recording the basic data of each sand mold, Yu Hua then based on the casting cooling experience
Formula to calculate the approximate cooling time.
"Okay." Lin Wan nodded, holding a pencil in her right hand and writing down the cooling time data on her notebook.
Compared with workers’ accumulated subjective experience over time, smelting gray cast iron requires more systematic statistics and analysis to obtain corresponding metallurgical data.
"Deputy leader Yu, how long does it take for the grenade casing to cool down?" At this time, Zhao Shu, the engineering section chief who was standing nearby and observing, asked: "The arsenal is preparing to pour the grenade casing."
"Chief Zhao, the grenade shell can be demoulded in 15 minutes. When it naturally cools to normal temperature, gray cast iron can be obtained." Yu Hua replied with a smile: "Remember to add ferrosilicon."
Fifteen minutes...
Zhao Shu nodded, turned and left.
Soon, four groups of casters began pouring grenade shells. In addition to six sand molds, a thousand prepared grenade shell sand molds were placed in the pouring area, divided into ten batches.
Lot of one hundred grenades.
Under the cover of night, the pouring operation of the iron factory started again. Different from the previous pouring machine parts, this time it was military production.
Hot and red molten iron was poured into the sand molds of the grenade shells one by one. In an instant, the sand was ignited like a candle, emitting orange-red flames.
The foundry team was responsible for pouring molten iron. Zhao Shu and Hu Zhigang, as technical cadres, followed Yu Hua's method to record the pouring time of each batch of grenade shell sand molds, and then marked the scheduled cooling time.
The first batch.
Second batch.
The fifth batch.
The eighth batch...
The iron water lanterns are lit up one after another, releasing gorgeous and dazzling flames. The picture looks as beautiful as a lantern festival, containing the atmosphere of Yancheng's era in 1937, and is poetic and picturesque.
"It's so beautiful." Yu Hua looked at this picture and smiled. This unique beauty of industrial version 0.1 is rare.
Lin Wan beside her nodded slightly, with a faint smile on her face, looked at the flaming sand mold on the ground, and then turned to look at Yu Hua.
"Professor, the sand molds for the mandrel and rollers are basically poured. Just demould and take them out when the cooling time comes. I plan to design the conveyor belt before leaving to improve the efficiency of raw material transportation." Yu Hua looked at Zhuang Qianding beside him and said.
According to the schedule, Yu Hua will leave early tomorrow morning to go to Yulin to inspect the specific site of the steel plant. There is not much time left.
Nowadays, it is only a matter of time before gray cast iron is successfully smelted. The arsenal's 60mm mortar project is solved by a two-roller cross-rolling mill. Yu Hua is preparing to point out the conveyor belt equipment before leaving.
"Okay, should I choose the belt type or the bucket type?" Zhuang Qianding nodded, supported Yu Hua's idea, and asked.
Belt conveyors mainly consist of belts as the transport carrier. Bucket conveyors, as the name suggests, consist of metal hoppers as the transport carrier. Both types are currently mainstream conveyor belt equipment.
“I think the belt type is better, it’s low cost and doesn’t have high technical requirements, while the bucket type is more expensive.”
Yu Hua gave his own thoughts: "After all, sometimes, being expensive is the original sin."
"Young man, you keep talking the same way. Classmate Lin, you stay here to help, while Yu Hua and I go to the office." Upon hearing this, Zhuang Qianding laughed and shook his head, and then made arrangements.
"Okay, Professor." Lin Wan nodded.
Later, Zhuang Qianding and Yu Hua left the blast furnace area of the iron plant and headed to the iron plant office not far away. On the way, they continued to discuss the technical details of the belt conveyor.
No conveyor?
Then just make it directly.
Anyway, there is a blast furnace, the arsenal also has a high-power DC motor for general-purpose vehicles and oxygen top-blown converter projects, and the materials and equipment are complete.
…
Time passes minute by minute.
Not long after, fifteen minutes passed, and it was time for the first batch of grenade shells to be demoulded.
At this time, the pouring operation at Liushugou Iron Works was still going on. There was no way around it. There was still a ton of molten iron in the blast furnace, which was enough to cast more than 5,000 grenade casings.
As the leaders in charge of the military industry and engineering departments of the Military Industry Bureau, Zhao Shu and Hu Zhigang had already arrived at the pouring area, standing next to the first batch of grenade sand molds, holding torches, waiting for the most important smelting results.
Whether white iron or gray iron is smelted is extremely important.
The shell demoulding work was carried out by the factory director Ma Tian. He seemed a little nervous, took a deep breath, and then opened the upper part of the grenade sand mold under the gaze of the two men.
Immediately afterwards, a ball of black quartz sand that was smoking and in a high-temperature state appeared. Martin held the iron pliers in his hand, cleaned off the quartz sand on the surface, and then took out a familiar metal casting from it.
It is a cylinder, hollow, with rhombus-shaped fragment grooves engraved on the inside. The appearance is rough and dark red, and the most important thing is that the whole body is gray.
"Chief, we seem to have succeeded. This is not the white iron that was smelted in the Soviet area before, but gray iron." The torch came close to the shell and saw the dark color of the whole body. The experienced Ma Tian was startled for a moment, and his face suddenly showed joy.
With a look of excitement in his eyes, he shouted towards Zhao Shu and the others.
Excited.
It comes from inner excitement.
As a worker who once worked in the Hanyang Iron Works, director Ma Tian has very rich iron-making experience. He can tell the difference between white iron and gray iron. The grenade shell in front of him is not the white iron smelted in the Soviet area.
But real gray iron!
"Old Ma, please double check whether it is gray iron." Zhao Shu spoke with respect and suppressed his excitement.
"I will never admit my mistake. This is the gray iron that was smelted by the Hanyang Iron Factory in the past. The white iron is very hard and will crack with just a slight hammer. Look at this grenade shell." Ma Tian nodded repeatedly and explained briefly.
, then hammer the shell with iron pliers.
"Ding!" The gray-colored shell did not shatter, but made a crisp metal impact sound.
"Haha, it really happened." Seeing this, Zhao Shu beamed and couldn't help laughing.
"It has been more than ten years, and gray iron has really been refined..." Hu Zhigang, who was standing next to him, also breathed a sigh of relief and couldn't help but feel happy about Zhao Shu.
Don't look at simple iron smelting, just the smelting of gray iron has troubled the organization for more than ten years.
The technical difficulty of smelting gray iron and white iron is not at the same level at all. The Soviet Area Arsenal organized technical cadres and workers to research gray iron smelting technology, but to this day, they still have not succeeded.
And now...
It turns out that just adding a small amount of ferrosilicon to the gray smelting iron and letting it cool slowly will be enough.
Such a simple smelting technology has blocked everyone for so many years.
When Hu Zhigang looked back at the meetings over the years in which he tried to smelt gray iron, his emotions were somewhat complicated, and Yu Hua's smiling face appeared in his mind.
If it weren't for Yu Hua, they don't know how long it would take to refine gray iron...
Soon, Zhao Shu reported the news of successfully smelting gray iron to Chen Kang.
Chen Kang was overjoyed when he received the news, and his mood was ups and downs. Really, the news of successfully smelting gray iron had a greater impact on him than the oxygen top-blown converter technology that Professor Zhuang and Yu Hua had been studying.
After all, oxygen top-blown converter technology is far away for him, and smelting gray iron is one of the biggest problems faced by the Military Industry Bureau.
"Have you mastered the technology of smelting gray iron?" Chen Kang took deep breaths continuously, forced himself to stay calm, pinched his dry throat, and asked Zhao Shu.
Zhao Shu nodded: "I got it. The secret lies in time and ferrosilicon. Ferrosilicon needs to be smelted with an electric furnace."
"Okay, okay, let the electric furnace steel plant make one furnace of ferrosilicon every day to supply the blast furnace." Chen Kang became more and more excited, his words trembled slightly, and after thinking in his mind, he gave the instruction: "Hu Zhigang!"
"have!"
Hu Zhigang on the right responded immediately.
"Bring me all the grenade sand molds from the arsenal right away. I won't sleep tonight because I want to hit the production record!"
Chen Kang, who was in an extremely excited mood, directly issued production tasks as the top leader of the Military Industry Bureau, just like he was rushing to achieve sales at the end of the month: "Also, start casting mortar shells immediately. The actual daily output of shell shells will be given to me."
Let’s get 300 pieces first, and remember the most important thing is to maintain quality and quantity!”
With the gray iron available, the 60mm mortar shell, which had been stuck on the drawing board, could finally begin production.
Although the output of artillery shells ≠ the actual output of artillery shells, it is still better than the output being zero.
In addition to this, produce more grenades.
The number of hand grenade shell sand molds made by the arsenal was not five thousand, but three thousand. In addition, there were fifty sets of shell steel molds.
In a word - rush production!
Of course, Chen Kang did not pursue high output alone, and also had strict requirements for the quality of grenade casings.
The quality of grenades manufactured by the Military Industry Bureau must be stable and reliable, which is very important, because this is a weapon that is to be handed over to soldiers.
If the grenade is of poor quality, it will explode immediately after pulling the cord, and the consequences will be self-evident.
In the past, there was no way to make such defective grenades. Now that the technical problems have been solved, we must not make such seriously defective grenades again.
Made in border area, reliable quality!
"Yes!" Hu Zhigang nodded, accepted the order, and left quickly.
"Chief, we have finally made gray iron." After Hu Zhigang and Zhao Shu left, Chen Kang quickly came to General Liu who was observing the pouring operation and told the news.
"Is this news true?" General Liu was stunned for a moment and asked seriously.
"It's 100% true and has been verified many times. With the help of Yu Hua, we successfully produced gray iron." Chen Kang affirmed: "Next, I will prepare to produce 60mm mortar shells and strive to increase the daily output of shells.
100 rounds, guaranteed quality and quantity.”
After hearing the arrangement given by Chen Kang, General Liu, who exuded an elegant atmosphere, nodded and affirmed: "It's not easy... You did a good job and didn't embarrass me. I'll go back and report the news to the boss first. I'll definitely
To protect the safety of Professor Zhuang and Yu Hua, this is the highest instruction from above."
"Yes, I understand! Except for the section chiefs, Comrade Zhao and the security guards, no one else in the Military Industry Bureau currently knows the identities of Professor Zhuang and others, and they claim to be hired technical experts." Chen Kang replied.
"good."
General Liu nodded when he heard this arrangement, turned around and left without wasting time.
After General Liu left, Liushugou fell into an unprecedented lively scene late at night, and the entire grenade production was in full swing in the physical sense.
Factory director Ma Tian directed the casters to carry out continuous pouring operations. Zhao Shu arranged for the demoulding workers to take out the grenade casings made of gray cast iron. Hu Zhigang stayed in the sand-turning room and directed the sand-turning workers in the iron factory and arsenal to make new grenade casing sand.
mold, and 60 mm mortar shell sand mold.
Boost production!
Boost production!
Boost production!
The soldiers and workers seemed to be working tirelessly. In just one hour, the production of grenade casings made of gray cast iron reached 300, and the production of 60mm mortar shells was ten.
Subsequently, the grenade casings and artillery shells that have been completely cooled naturally are sent to the arsenal for the production of hand grenades and artillery shells in complete condition.
…
The next day.
The rising sun rises in the east, ushering in a new dawn on the Loess Plateau that has been sleeping all night.
At the entrance of Liushugou, a Dodge truck was ready to go. Guard Lu Junyu and three soldiers with live ammunition stood beside the truck, standing tall in military posture.
Today is the day when Yu Hua sets off for Yulin for inspection.
Yu Hua and Chen Kang were bathed in the early morning sunshine. They walked unhurriedly on the cinder road toward the entrance of Liushugou like friends.
"Didn't you sleep last night?" Chen Kang yawned and asked with concern.
"After sleeping for a while, I worked with the professor all night to draw the drawings of the belt conveyor. The iron ore and coke feed inlet of the blast furnace is equipped with a conveyor belt, which can greatly improve the efficiency of raw material transportation. In addition, I also designed a hand-operated
A ball mill is a roller with many iron balls inside, which can grind iron ore, saving labor and is very simple to manufacture."
Yu Hua enjoyed the morning sunshine very much, squinted his eyes, and showed a comfortable expression: "There is also a two-roller cross-rolling machine. Once this machine is completed, the arsenal will be able to produce seamless steel pipes. However, due to the lack of machine tools for the time being, we want to make
It may take some time before a real mortar is produced."
Making seamless steel pipes is the first step in making mortars, and then a series of processing steps are required.
"I'm not a person who always talks about thank you, but I still want to say thank you to you."
Chen Kang heard the information given by Yu Hua and thanked him softly: "The current situation of the Military Industry Bureau is inseparable from your efforts. Thank you for giving us Yu's Seven Towers technology, and thank you for your continued help.
We have found Professor Zhuang."
"This is what I should do."
Yu Hua looked at Chen Kang's bloodshot eyes and responded with a smile: "You didn't sleep last night either?"
"I stayed up all night last night working on grenade production."
Chen Kang nodded and said with a rather mysterious smile: "Would you like to guess how many grenades the arsenal produced last night?"
"As for grenades... 1,000?" Hearing this, Yu Hua pondered thoughtfully and gave the psychologically estimated production data.
Grenade and grenade casing are not the same thing. Yu Hua is still curious about the current daily output of grenades at Liushugou Arsenal. According to the scale, it is about a thousand pieces.
"My guess is pretty close. A total of 1,165 grenades were produced last night. This is the highest single-day output of grenades currently produced by the Military Industry Bureau, and it is 38 times the single-day output of yesterday."
Chen Kang sighed softly: "We previously planned to produce 10,000 grenades per day, but we did not expect that the daily output would reach 1,000 levels so quickly, which has already caught up with the level of the Soviet Area General Arsenal."
Planned ten thousand and actual one thousand, the two concepts have completely different impacts.
Yesterday, the daily output of grenades was 30, hovering around double digits, but today it was 1,165, directly breaking through the thousand level and soaring to four digits.
To be honest, Chen Kang feels a little illusory now, and feels that this production data is unreal. Looking at the past, only the Soviet Area General Arsenal in its heyday could reach this level.
But the problem is that the Soviet Area General Arsenal only has a very limited time when its daily output of hand grenades exceeds 1,000. Most of the time, it can produce several hundred black powder hand grenades every day, which is a high production level.
"This shows that your work is very effective. I remember that you were not in charge of the army before? How come you were transferred to be the director of military industry." Yu Hua smiled and asked curiously.
Yu Hua has always been curious about the brigade commander serving as director of military industry.
There was no other way. According to his understanding of the brigade commander, at this point in time, the brigade commander was still studying at the Anti-Japanese University. In August, he was immediately accepted and reorganized into the Eighth Route Army. He took up his post directly and served as the commander of the 386th Brigade.
Today, Chen Kang is the head of the Military Industry Bureau.
The world is so wonderful.
"You ask me, who am I asking? I didn't know anything about military production before, so I learned it bit by bit every night." Chen Kang shook his head helplessly and looked at Yu Hua: "However, there is something I can tell you.
, I should be resigning soon and going to the army, and my successor will be Li Qiang."
"Li Qiang?" Yu Hua stopped, with a look of confusion on his face.
"You may not know anything about him. Li Qiang's original name is Zeng Peihong. He developed the first radio transceiver for the organization. He was the chief of the Special Branch Transportation Section. He has a very high talent in the field of radio and is also an outstanding genius."
Looking at the confusion on Yu Hua's face, Chen Kang smiled and briefly introduced the confidential information about Li Qiang: "Not long ago, he went to the Soviet Union to study and published a paper on "Sending Diamond Antennas." It is said that this paper had a very good response.
It shocked the Soviet communications academic community. As a person, he has a friendly personality and is easy to get along with. But he and I have no common topics. When we got along before, this guy always thought the questions I asked were very simple and made me look like an idiot.
Same."
Zeng Peihong!
Damn it, Doraemon of the Red Army!
Yu Hua was shocked when he heard Li Qiang's alias and identity information. The name Li Qiang had not yet evoked his memories, but the name Zeng Peihong was too familiar.
Ma Lie is on top. This is a famous top boss in history. In later generations, he was called "the Doraemon of the Red Army" and "a super genius who is more like a time traveler than Wang Mang."
So the question is, how awesome is this boss Zeng Peihong?
If Yu Hua remembers correctly, Mr. Zeng Peihong graduated from the civil engineering department of Nanyang Road and Mine College in his early years. He was born in civil engineering. Since the organization needed arms, but they couldn't buy them on the market, he could only find Zeng Peihong, which means you majored in civil engineering. Rounding up is
Study chemistry and develop munitions for the organization.
Without saying a word, Zeng Peihong tinkered with making explosives and grenades by himself, and successfully produced the first batch of arms in the organization.
Later, due to the organization's lack of radio equipment, it was unable to contact the Soviet Union. In addition, radio stations were under highly controlled equipment at this period and could not be obtained at all. I had no choice but to find Zeng Peihong again and said that you were studying civil engineering. Rounding it off, you studied radio majors and researched and developed for the organization.
radio station.
Zeng Peihong immediately switched to the field of radio research and development, and then showed his extremely amazing radio research talent. In 1929, he single-handedly developed the first radio station in the history of the organization.
There is no need to explain how valuable it is for a man to build a radio station in 1929.
In the 1930s, which is what Chen Kang said, he went to the Soviet Union to study a few years ago and published an English paper "Sending Rhombus Antennas". Yu Hua didn't know how awesome the content of this paper was. He hadn't read it, but Yu Hua knew it.
This paper was so good that the Soviet Academy of Communications Sciences had to directly promote Zeng Peihong, a student, to the Academy's seventh radio expert, and the research result was named "Li Qiang's Formula".
You must know that the Soviet Union’s radio communication research level ranks among the best in the world. As a foreigner, Zeng Peihong directly became the seventh expert of the Soviet Academy of Communications Sciences. When Yu Hua read this, he was already shocked.
After the outbreak of the Anti-Japanese War, Zeng Peihong returned to China and took charge of military production and research and development in the base area, greatly improving the level of military production. He single-handedly supported the military production system in the base area and built a certain basic level of heavy industry.
Gun factories, steel mills, explosives factories, kerosene factories, pharmaceutical factories...these are the achievements of Mr. Zeng Peihong, or what makes him awesome.
If you need a radio, get it immediately.
If you want arms, get them immediately.
The war of resistance is coming. We need guns, explosives and medicines. We need to get them done immediately.
This is why it is known as the "Red Army Doraemon".
