As the ten-ton crane using a dual-motor drive system completed the welding of the last component, the most important infrastructure in the steel plant was assembled. As the chief engineer of the steel plant, Yu Hua and a group of skilled workers walked down the stairs.
Escape to a safe area.
Next, carry out the driving and lifting test.
The importance of driving is self-evident. Whether it is transporting molten iron or molten steel for irrigation, it must be lifted by driving. It is impossible to do this kind of thing just by manpower.
The total cost of this bicycle is as high as NT$10,000. The power system is composed of two 100KW high-power DC motors imported from the United States, with a total power of 200KW. Together with the transmission system and gears to amplify the torque and increase the lifting force, it is enough to rank among the super high-power steel plants.
The unit price equipment club is brothers with machines such as electroslag remelting furnaces, air separation equipment, and air hammers.
The lifting test is divided into a conventional test and a load test. The conventional lifting capacity is up to ten tons, and the loaded lifting capacity is up to twelve tons. The main test is whether the driving can reach this value.
Many workers are busy preparing for the test.
The steel plant's 500KW total power diesel generator set worth tens of thousands of dollars was started to operate and supply electricity. The lifting test piece was composed of dozens of steel plates with a total weight of about ten tons, which were tied with wire ropes and placed directly under the driving vehicle.
Finally, a young crane worker who had undergone accelerated professional theoretical training and strict assessment walked up the stairs and entered the simple but comprehensive driving cab.
everything's ready.
Yu Hua wasted no time and gave an order to announce the start of the test.
At this moment, Yang Zhi, the leader of the Red Regiment who was leading the team to build the steel plant, more than a hundred soldiers, as well as steel plant workers and backup crane workers, all stared at the ten-ton crane above.
Everyone present knew the importance of this machine. Without it, neither the experimental furnace nor the future steel plant would be able to operate normally.
Feeling the attention of everyone, Sun Hong, the young lifter who was responsible for this test task, did not panic at all. He had a calm face and a calm heart. He started driving in an orderly manner and in accordance with the standard operating procedures. He is a veteran of the First Red Division and graduated from a junior high school before joining the team.
He is one of the few highly educated soldiers in the First Red Division.
After the two motors were powered on and activated, Sun Hong checked the equipment according to regulations and confirmed that all parts were normal. He held the joystick tightly with both hands and lowered the crane hook steadily.
good.
Yu Hua looked at the operation process of the crane worker and nodded, with a look of affirmation in his eyes.
As the hook with an anti-detachment design descended above the steel plate, the two soldiers immediately stepped forward, put the steel rope binding the steel plate into the hook, and then retreated to a safe area.
Immediately afterwards, under the watchful eyes of everyone present, the driving transmission device output the maximum torque and steadily lifted the ten-ton steel plate up to a height, leaving the restraints of the ground and hanging in the air.
Then, it moves laterally at a speed of 0.5 meters per second to the intended destination.
When it descends and touches the ground, it will automatically decouple.
"Bah, bang, bang!" In an instant, a wave of applause suddenly sounded, spreading throughout the huge factory.
"It's basically done." After watching the entire routine test process, Yu Hua smiled and relaxed in his heart. The highlight of today's test was the routine test. The situation was as expected. The entire driving and lifting process was operating normally and performed extremely well. It basically reached
Design level.
Routine test, passed.
Next, only the final load test is required, and then the ten-ton driving vehicle can be declared completed and accepted.
The atmosphere on the field was lively and everyone was happy. Five or six workers were busy carrying out load testing.
"Report to the chief, there is an urgent call from headquarters." At this moment, Lu Junyu's figure suddenly appeared, quickly entered the steel plant, and came to Yu Hua's side to report.
Yu Hua was startled for a moment, then took the telegram and read it, and the brief content came into view.
Pingjin has fallen, return to Yancheng as soon as possible. ——Chen, July 31st.
After seeing this news, Yu Hua was stunned. Unexpectedly, the time had already arrived on August 1st. He was well aware of the seriousness of the fall of Pingjin.
For future generations, the fall of Pingjin is just a description in a history book. Many people will ignore it after just one glance. However, for China in 1937...
This was the beginning of the disintegration of mountains and rivers, and it was also a super event that shocked China and the world.
The failure of the battle to defend Nanyuan eventually led to the fall of Pingjin and the official outbreak of the all-out war of resistance. If nothing else goes wrong, in thirteen days time, the August 13 Songhu Battle, which shocked both China and foreign countries with a million-level troops, would begin.
After the fall of Pingjin, the gate of North China was opened, and the land of China was in danger of overthrow.
The Japanese army originally planned to divide its troops into three routes from Pingjin, move south along the Jinpu Line, Pinghan Line, and Tongpu Line, penetrate the land of China from south to north, and reach Nanjing, achieving the strategic goal of virtually destroying China within three months.
In order to disrupt the Japanese army's strategic goal of penetrating China from north to south, the CSI brother took the initiative to start a war with the Japanese army in the Songhu area, forcing the other side to change the direction of their strategic attack and choose to attack from east to west.
From a strategic perspective, this is a good move.
However, due to his fondness for micro-management and unrealistic illusions about the League of Nations, the main force of the National Army suffered heavy losses in the Songhu Battle, which in turn caused a series of subsequent chain reactions.
The core reason for the fall of Nanjing has a close relationship with the failure of the Songhu Battle.
"China's comprehensive national strength lags far behind Japan's. I am unable to change the general direction of the war of resistance. I only hope that Zhongzheng will be better than before after knowing Japan's ambitions and goals in advance."
"The fall of Pingjin means that the window period for the north's external contacts has officially ended. From now on, we can really only rely on ourselves. Fortunately, the infrastructure construction of the test furnace has been completed and production is about to be completed. This is good news. This message should ask me to go back.
There was a meeting to discuss, and no surprise, it was probably about weapons production. After all, the Red Army will soon transform into the Eighth Route Army and go out to fight the war."
"For the Military Industry Bureau, the main direction of first basics and then weapons production cannot be changed. The test furnace must be completed in one go. However, some resources can be allocated to the production of weapons and ammunition to increase the output of bullets, grenades, landmines, and mortars.
I don’t know how the official imitation rifle project is progressing, so I’ll just go back and find out.”
"In any case, the test furnace is the most important."
Yu Hua's mind was running at high speed, analyzing and thinking comprehensively about the impact of the fall of Pingjin.
Clarify ideas and formulate countermeasures.
After counting the interest.
"Commander Yang Zhi, I have to rush back to Yancheng immediately. The steel factory is temporarily left to you. How much raw material is stored? The steelmaking work will start soon. Before the production of walking tractors, the existing transportation capacity cannot meet the demand.
To meet the needs of the steel plant, we must prioritize the storage of raw materials." Yu Hua exhaled softly, his eyes as deep as the starry sky revealed an inexplicable color, put away the message, looked at Yang Zhi beside him, and gave instructions.
"Yes, I promise to complete the task!" When Yang Zhi saw this, he straightened his back and raised his hands in salute without asking what the emergency was.
"goodbye."
Yu Hua nodded, did not waste any more time, and turned to leave with Lu Junyu.
The matter was urgent. After simply packing up the luggage, the five war horses galloped away. Four guards including Yu Hua, Lu Junyu and others quickly left Yulin and rushed to Yancheng.
After these days of training, Yu Hua's horse riding skills have improved steadily. Although he is not as good as Lu Junyu, he at least knows how to control a horse.
To be honest, if it weren't for the fact that horse riding requires the cooperation of man and horse, Yu Hua's operating skills would have been perfected long ago.
The thinking in the head is similar to a physical system, which is no joke.
Time passed, and at eleven o'clock that night, Yu Hua and the five men changed horses three times at the Red Army stations in various counties on the way, and finally arrived at the Yancheng Military Industry Bureau. They met Chen Kang with a serious face and took the lead in understanding the situation.
Things did not go beyond his expectations. The reason why Chen Kang asked him to return quickly was because of the weapons production.
…
One o'clock.
Military Industry Bureau, cave dwelling conference room.
The incandescent lamp hanging from the top emits bright and dazzling yellow light, illuminating the entire conference room. Below, the heads of various departments of the Military Industry Bureau and all members of the highest technology group are sitting in corresponding positions, and the atmosphere is solemn.
"Today is August 1st. To make a long story short, according to the news from comrades in the north, the Pingjin area has fallen the day before yesterday. Song Dynasty followed the order of Nanjing to withdraw its defenses to the south. The Japanese army invaded Tianjin and burned, looted and set fire to it, including the private Nankai University.
It was bombed by Japanese bombers and then set on fire. It was in ruins, even worse than when the Eight-Power Allied Forces invaded the Old Summer Palace."
Chen Kang's face was serious and heavy, his eyes looked around everyone present, and finally he gave Yu Hua a special look, and slowly announced the latest news about Peiping: "In addition, Peking University and Tsinghua University have been attacked by the Japanese army one after another and have been captured and looted."
The private Nankai University became the most influential Anti-Japanese War education base in the country because of the "Northeast Geography Textbook" compiled by President Zhang Boling, which exposed Japan's ambition to invade China and awakened the Chinese people's determination to resist Japan.
Therefore, in the eyes of the Japanese army, the private Nankai University was a thorn in their side, and they must carry out the most thorough humane destruction. After breaking through Tianjin City, the Japanese army immediately went straight to the private Nankai University, mobilized bombers to bomb it, and then set it on fire.
.
Fortunately, it was during the summer vacation, and the three schools in northern Qing and Nankai moved their education to the south in advance, so there were no male or female students in the school. Otherwise...
The atmosphere became increasingly solemn, and everyone present was filled with anger, gnashing their teeth against the atrocities committed by the Japanese army. When Chen Kang finished his last words, everyone's eyes turned to Zhuang Qianding and Yu Hua.
Because Tsinghua University is Yu Hua’s alma mater and where Zhuang Qianding taught.
"Don't worry, I'm fine."
Zhuang Qianding took a deep breath. Although he was angry, he still remained calm. Anger could not change anything. Pingjin fell, and Tsinghua University was naturally not immune to the disaster. This was something that had been expected.
"I'm fine too, don't worry."
Yu Hua responded: "I believe that China will definitely win. The Japanese invaders will eventually pay the price of invading China with their land and their blood. This is exactly what we have to do."
There is nothing to be angry about and nothing to be painful about.
Everything will eventually be paid for with blood.
"In view of the fact that the Japanese aggressors are very likely to invade south after seizing Pingjin, superiors are in contact with Nanjing. Our Red Army troops will soon change their combat order to the National Revolutionary Army and go out to fight against the Japanese aggressors to resist the invasion. The headquarters has instructed our Military Industry Bureau to increase the number of weapons and ammunition of all types.
Production supplies the troops.”
Seeing Zhuang Qianding and Yu Hua react like this, Chen Kang nodded, feeling a little relieved, and continued: "Professor Zhuang, I need data from the highest science and technology group. First, how many can be mobilized without affecting the wartime production plan?"
production capacity to increase the production of various weapons and ammunition, and secondly, how long it will take for the test furnace and Yulin Iron and Steel Plant to be completed and put into production."
