Chapter 278 This is not a test of the cadre's imagination!
This is a bold guess.
Seeing the expression of Comrade Professor Zhuang, Lin Wan was startled for a moment, as if she realized something, and her words were a little surprised: "Could it be that...Professor Zhuang is preparing to join the organization under the influence of Yu Hua?"
"You shouldn't join directly, but at least you can help us. Otherwise, with Yu Hua's temperament, he will not expose himself at will, let alone initiate this emergency meeting." Liu Wei's eyes were filled with thoughts, and he said slowly.
: "If Professor Zhuang can help us, it will be a huge help to the entire base area."
Liu Wei knew the situation in the base area very well. After all, he was the top person in charge of the Northern Department and had the right to know.
Now, the pre-war large-scale production in the base area, which has been going on for more than two months, has achieved remarkable results. It is much better than the initial poverty-stricken situation in the base area.
But this is not enough to be proud of.
Because there are still quite a few problems in various areas covered by the entire pre-war large-scale production plan.
Metallurgy, military industry, electric power, and mechanical processing are short of talents, technology and equipment. In order to achieve the two general goals of "establishing a lower-level basic industry" and "independently producing light weapons military industry" formulated in the pre-war mass production plan,
There is still a very long way to go.
Fortunately, with the coking technical information and weapons production suggestions given by Yu Hua not long ago, the problems in the base area's metallurgical and military industries have been alleviated.
The first is to establish the most basic coking system with the help of Yu Hua's coking technical data to solve the problem of coke required for blast furnace ironmaking.
Second, the Military Industry Bureau invited a group of senior generals in the army to discuss and study the weapon model suggestions given by Yu Hua, and finally determined that the rifle model was a medium-sized formal rifle, and the mortar model was a tribute to the classic, imitating the Brand 60 mm mortar.
The rifle models and mortar models have targets, but when it comes to the actual research and development process, the technical situation faced by the Military Industry Bureau is far more complicated than imagined, resulting in very slow research and development progress.
Generally speaking, the development of large-scale production before the war had reached a bottleneck period, and more support was urgently needed.
If Professor Zhuang is really here to help the base area, as they analyzed, this is really great news.
After listening to the resume information about Professor Zhuang, Liu Weiguang knew that this Tsinghua professor whom he had never met before was definitely a top scientist.
What is most lacking in the base area is this kind of talent.
"You're right." Lin Wan nodded in response.
Liu smiled: "What time is it?"
"6:10 minutes." Lin Wan raised her right hand, looked at her watch, and responded.
"It should be almost time, let's go to the door to greet you." Liu Wei heard that it was almost time, and then put out the cigarette butt in his hand.
Greeting guests personally is the way to treat guests.
Lin Wan nodded, followed Liu Wei, left the room, and headed towards the door of Ke Lai Teahouse.
Soon, Liu Wei and Lin Wan came to the door of the teahouse and stood quietly.
"Buzz!" Not long after, accompanied by the sound of a car engine working, a Buick car parked steadily in front of the teahouse. Through the window, you could see Yang Xiu sitting in the passenger seat, and Yu Hua and Yu sitting in the back seat.
A man with an unfamiliar face.
Lin Wan quietly looked at Yu Hua, whom she had not seen for a long time in the car, with a slight smile on her face.
After the vehicle stopped, Yang Xiu quickly got out of the car, went to the back seat, opened the door, and stepped aside, showing respect to the two people in the back seat.
If Yu Hua's knowledge was so high that he admired him, then Professor Zhuang Qianding, who worked at National Tsinghua University, was undoubtedly someone he could only look up to.
Professor of National Tsinghua University!
Yu Hua and Zhuang Qian Ding got off the bus from the right side in an orderly manner and stood in front of the teahouse gate.
At this time, Liu Wei stepped forward steadily, with an elegant smile on his face, and stretched out his right hand: "Classmate Yu, long time no see."
"Steward Liu, long time no see."
Yu Hua nodded to Liu Wei, stretched out his right hands to hold them together, greeted politely, and then let go naturally.
After a brief exchange of greetings, Yu Hua turned to introduce Zhuang Qianding next to him: "Steward Liu, this is my mentor, professor and director of the Department of Mechanical Engineering at National Tsinghua University - Zhuang Qianding."
"Hello, Professor Zhuang, my name is Liu Wei. I welcome you on behalf of the Northern Department. Just call me Butler Liu." Liu Wei's eyes fell on Zhuang Qianding, and he stretched out his right hand again and said with a smile.
"Hello, Steward Liu, it's a pleasure to meet and get to know you." Professor Zhuang was dressed very formally today, wearing a suit, exuding the elegance of a top scholar. He shook hands with Liu Wei generously and nodded with a smile.
He had only heard of the red organization before, but had never had such close contact with them.
"Hello, professor, I am Lin Wan, a student at Peking University, and I am also the chief of the Northern Science Department." Lin Wan stepped forward, bowed slightly, and greeted Professor Zhuang as a student.
"Hello, classmate Lin, I heard Yu Hua talk about you, and you are very talented in the field of mechanical design." Zhuang Qianding looked at Lin Wan, nodded, and said.
Before this meeting, Yu Hua had informed Liu Wei, Lin Wan and others about relevant information. Zhuang Qianding was quite curious about Lin Wan, firstly because of her female identity, and secondly because of Yu Hua's evaluation and top mechanical design talent.
"You are exaggerating, Professor. The student's talent is average." Lin Wan was stunned for a moment, glanced at Yu Hua, felt a little embarrassed, and said modestly.
Zhuang Qianding smiled and said nothing.
"Professor Zhuang, classmate Yu, let's go in first. This is not a place for conversation." The two parties had a brief exchange, and Liu Wei spoke up at the right time, signaling everyone to enter the teahouse.
"It's up to you to do as you please, Butler Liu." Zhuang Qianding nodded and smiled.
A smile appeared on Liu Wei's face, and he immediately led everyone through the gate and into the teahouse.
…
Inside the teahouse, in the previous meeting room, a pot of Longjing was placed on the table. The guard quietly left and closed the door.
There are two security guards standing outside the conference room, responsible for security matters.
Liu Wei stood on his seat, lifted the teapot with his right hand, and poured tea for Zhuang Qianding and Yu Hua himself, and then poured tea for Lin Wan and himself respectively.
After pouring, drink tea.
Yu Hua picked up the tea cup and took a sip of Longjing. Well, it still tasted familiar and delicious.
The four of them drank tea, and Liu Wei was the first to put down his teacup and get down to business.
"Classmate Yu, what is particularly important?" Liu Wei glanced at Professor Zhuang and asked.
"Steward Liu, Jin Yu, we are meeting today because of a technology that can change the destiny of China." Yu Hua didn't waste any time and went straight to the point, staring at Liu Wei and Lin Wan in front of him, his voice was solemn and solemn.
Technology enough to change China's destiny?
"Classmate Yu, what kind of technology is this?" Liu Wei was slightly stunned when he heard this, his face changed, and his tone was a little confused and solemn.
Naturally, Yu Hua would not take aim without aim. So, what exactly is this technology that can change the destiny of China?
As soon as the words came out, Liu Wei and Lin Wan's eyes were all focused on Yu Hua.
Yu Hua did not answer this question, and turned his gaze to Zhuang Qianding beside him.
"Oxygen top-blown converter technology."
Zhuang Qianding said solemnly, taking out the oxygen top-blown converter design drawings he carried with him from his briefcase, placing them on the table and handing them to Liu Wei: "This technology was pioneered by Yu Hua. It is based on the principle of oxygen steelmaking. It uses oxygen lances to convert high
Pure oxygen is fed into the steelmaking converter to achieve a high-efficiency steelmaking process. Currently, the time required for one furnace of steelmaking in an open-hearth furnace is about 7-12 hours, and the time required for one furnace of steelmaking in an oxygen top-blown converter is about 25-40 minutes.
In fact, the reaction time for molten steel smelting is only about 15 minutes."
"15 minutes?!" As Professor Zhuang Qianding finished speaking, while Liu Wei was still in a confused state with only a little knowledge, Lin Wan, who had a little knowledge of steel metallurgy, had already widened her eyes and showed an extremely shocked expression.
"Yes, the smelting is completed in fifteen minutes, and the rest of the time is spent on charging and tapping." Yu Hua spoke up at this time, nodding in confirmation.
Fifteen minutes of molten steel smelting reaction time.
The total time interval is 25 minutes to 40 minutes.
Lin Wan carefully picked up the design drawing of the oxygen top-blown converter and looked at it carefully. At this moment, no words could describe the shock and disbelief in her heart.
"Comrade Lin Wan, is there anything unusual or special about this fifteen-minute smelting time?" Looking at Lin Wan's reaction, and feeling the solemnity of Yu Hua and Zhuang Qian Ding, Liu Wei, who was not familiar with the steel industry, said
Full of doubts in my heart, I sorted out my words a little and asked.
It seems that this technology is indeed amazing.
"Comrade Professor, this smelting time itself is extremely abnormal. Assuming that it takes 7 hours to make one furnace of steel in a 100-ton open-hearth furnace, then only about three furnaces of molten steel can be produced in 24 hours a day. Without considering the quality loss of steel slag and other substances, then
The ideal total mass is equal to 300 tons."
After hearing Liu Wei's inquiry, Lin Wan finally recovered from the shock, briefly collected her thoughts, and slowly explained: "Now based on the calculation of the smelting time of this oxygen top-blown converter technology, assuming it is also a 100-ton converter
, taking 30 minutes to smelt one furnace, 48 furnaces can be smelted in 24 hours a day, what is 48 furnaces multiplied by 100 tons?"
"How much is 48 furnaces times 100 tons..." Liu Wei was stunned.
At this moment, he was really stunned.
The whole person's brain suddenly went blank, and a number echoed in the center of his mind - 4800 tons!
Material: Steel!
Looking at Liu Wei's dull and incredulous expression, Yu Hua and Lin Wan looked at each other without warning. Only when the professor understands the concept of this data can he truly understand the true value and value of oxygen top-blown converter technology.
importance.
It is no exaggeration to say that oxygen top-blown converter technology could completely determine China's national destiny and future in 1937.
Only by understanding its value and importance can we fully protect it.
The whole of China can ensure that the oxygen top-blown converter does not fall into the hands of the Japanese, only organization.
The conference room remained quiet, and the three of them remained silent, allowing Liu Wei to quietly digest the shocking news.
"Professor Zhuang, classmate Yu, that is, the oxygen top-blown converter can smelt 4,800 tons of steel every day, right?" After several breaths, Liu Wei came back to his senses and was able to digest what Lin Wan explained.
After receiving the message, he raised his head, his eyes revealed almost trembling excitement and excitement, and looked at the two of them. His words clearly and accurately reproduced this professional terminology.
Steel!
4,800 tons of steel every day!
This is an astronomical figure that Liu Wei cannot imagine.
Calculated based on 4,800 tons of steel per day, as long as this oxygen top-blown converter is installed, the annual steel production in the base will instantly increase to 1.7 million tons.
What is the concept of 1.7 million tons?
Liu Wei didn't know, but he could compare it. The annual steel production in Nanjing, which gathered the strength of the whole country, did not exceed 50,000 tons.
One is 1.7 million tons, the other is 50,000 tons...
At this moment, Liu Wei felt like he was going crazy. He finally understood why Lin Wan, who was usually very steady, reacted like this.
Damn it, this is not testing the cadres’ imagination, but destroying the cadres’ values and cognition!
Liu Wei originally thought that the big thing to talk about today was that Professor Zhuang was suspected of helping the organization, but he never thought that Yu Hua would directly fix this for him and drop a bombshell.
"Yes, but not completely right. If the steelmaking process is well controlled and the charging and tapping time is shortened and controlled to about 30 minutes, theoretically, the daily output of the 100T oxygen top-blown converter can indeed reach 4,800 tons, but we are temporarily
We cannot make a 100T converter, and the raw material supply system in northern Shaanxi cannot bear it."
Zhuang Qianding shook his head. Out of scientific rigor, he pointed out that it was necessary to meet the daily production requirement of 4,800 tons of steel. He poured a basin of cold water on Liu Wei and replied seriously: "This is a 2T test furnace designed by Yu Hua and I."
, a single total smelting takes about 30 minutes, with a daily output of 96 tons of steel and an annual output of 35,000 tons."
