Chapter 321 The Fall of Pingjin!

With the completion of the welding of the last component by a ten-ton crane using a dual-motor drive system, 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 went down the stairs and retreated. to a safe area.

Next, carry out the driving test.

The importance of driving is self-evident. Whether it is molten iron transportation or molten steel transportation and irrigation, it must be hoisted by trucks. It is impossible to handle this kind of thing by manpower alone.

The total cost of this car is as high as 100 oceans. The power system is composed of two 200KW high-power DC motors imported from the United States, with a total power of [-]KW. With the transmission system and gears to amplify the torque and increase the gravity, it is enough to rank among the ultra-high steel plants. The unit price equipment club is brothers with electroslag remelting furnaces, air separation plants, and air hammers.

The lifting test is divided into a conventional test and a load test. The conventional lifting is up to ten tons, and the load is up to twelve tons. The main test is whether the driving can reach this value.

Many workers have been busy preparing for the test.

The 500KW diesel generator set with a total power of tens of thousands of oceans in the iron and steel plant started operation and supplied electricity. The lifting test piece was composed of dozens of steel plates with a total weight of about ten tons, which were bundled with steel wire ropes and placed directly under the traveling vehicle.

Finally, a young crane worker who has undergone quick professional theoretical training and strict assessment, walked up the stairs and entered the simple but comprehensive driving cab.

everything's ready.

Yu Hua did not delay, and gave an order to announce the start of the test.

At this moment, Yang Zhi, the head of the Red First Regiment who led the team to build the steel factory, more than [-] soldiers, as well as steel factory workers and backup crane workers, all stared at the ten-ton truck above.

Everyone present knew the importance of this machine. Without it, neither the test furnace nor the future steel plant would be able to operate normally.

Feeling the attention from everyone, Sun Hong, the young crane worker who was in charge of the test task, did not panic at all, his face was calm, his heart was calm, and he started driving in an orderly manner according to the standard operating specifications. Education, is a rare soldier with a high degree of education in the first red division,

After the two motors were energized and activated, Sun Hong checked the equipment according to the regulations, confirmed that all parts were normal, held the joystick tightly with both hands, and lowered the crane hook steadily.

Not bad.

Yu Hua looked at the operation process of the hoist and nodded, with a certain look in his eyes.

As the hook with anti-decoupling design descended to the top of the steel plate, the two soldiers immediately stepped forward, put the steel rope tying the steel plate into the hook, and then retreated to a safe area.

Immediately afterwards, under the watchful eyes of everyone at the scene, the driving transmission device outputted the maximum torque, and stably lifted the ten-ton steel plate to the height, leaving the shackles of the ground and hanging in the air.

Afterwards, it traverses at a speed of [-] meters per second to reach the intended destination.

Descend and touch the ground, the hook will automatically disengage.

"Papapa!" In a flash, the applause resounded like a tidal wave, spreading all over the huge factory building.

"It's basically done." Yu Hua smiled and relaxed after watching the entire routine test process. The highlight of today's test is the routine test. As expected, the whole crane lifting process is running normally, with excellent performance, basically reaching design level.

Routine test, passed.

Next, only the final load test is required, and the ten-ton vehicle can be declared to have completed the test and be accepted.

The atmosphere on the field was lively and everyone was happy. Five or six workers were busy doing load testing.

"Report to the head, there is an urgent call from the headquarters." At this moment, Lu Junyu's figure suddenly appeared, hurriedly entered the steel factory, and came to Yu Hua's side to report.

Yu Hua was stunned for a moment, then took over the telegram and read it, and the brief content entered his line of sight.

Pingjin fell, and quickly returned to Yancheng. – Chen, July 31.

Seeing this news, Yu Hua was stunned for a while, but he didn't expect that the time had come to August [-] unknowingly, and he was well aware of the seriousness of the fall of Pingjin.

For later generations, the fall of Pingjin is just a description in a history book, and many people will ignore it at a glance. However, for China in 1937...

This is the beginning of the fragmentation of mountains and rivers, and it is also a super event that shocked China and foreign countries.

The failure of the defense of Nanyuan eventually led to the fall of Pingjin, and the full-scale war of resistance officially broke out. If nothing else, in another [-] days, the battle of August [-] Songhu, which shocked both Chinese and foreign troops to the level of one million, will start.

After the fall of Pingjin, the gate of North China was opened, and the land of China was in danger of overturning.

The Japanese army originally planned to divide its troops from Pingjin into three routes, 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 substantively destroying China within three months.

In order to disrupt the Japanese army's strategic goal of penetrating China from north to south, Brother Zhongzheng took the initiative to choose to fight the Japanese army in the Songhu area, forcing the other party to change the direction of strategic attack and choose to attack from east to west.

From a strategic point of view, this is a good move.

However, because of his fondness for micro-manipulation and unrealistic fantasies about the League of Nations, he eventually caused heavy losses to the main troops of the Warring States Army in the Songhu Battle, which in turn caused a series of subsequent chain reactions.

The core reason for the fall of Nanjing was closely related to the failure of the Battle of Songhu.

"China's comprehensive national strength is far behind Japan. I can't change the general direction of the Anti-Japanese War. I just hope that after knowing Japan's ambitions and goals in advance, Brother Zhongzheng can be better than before."

"The fall of Pingjin means that the window period for the North's foreign contacts has officially ended. The next step is really only on one's own. Fortunately, the basic construction of the experimental furnace has been completed, and the production is about to be completed. This is good news. Now this telegram should let me go back. The meeting was held to discuss, no accident, it was probably about the production of weapons, after all, the Red Army will soon change into the Eighth Route Army and go out to fight against Japan."

"For the Military Industry Bureau, the main line direction of first basics - then weapons production cannot be changed, and the test furnace must be completed in one go. However, some resources can be diverted to the field of weapons and ammunition production to increase the output of bullets, grenades, mines, and mortars. I don't know how the official rifle project is progressing in the imitation, so I just went back to find out."

"In any case, the test furnace is the most important."

Yu Hua's mind was running at a high speed, and he analyzed and thought about the impact after the fall of Pingjin.

Clarify your thoughts and come up with countermeasures.

After counting.

"Captain Yang Zhi, I want to rush back to Yancheng immediately. The steel plant will leave it to you for the time being. How many raw materials are stored? The steelmaking work will start soon. Before the walking tractor is not in production, the existing transportation capacity cannot meet the requirements. The steel plant needs to store raw materials first." Yu Hua let out a sigh of relief, his eyes as deep as the stars showed inexplicable color, put away the telegram, looked at Yang Zhi beside him, and instructed.

"Yes, the task is guaranteed to be completed!" Yang Zhi saw this, without asking what the emergency was, he straightened his back and raised his hands to salute.

"Goodbye."

Yu Hua nodded, and without further delay, turned and left together with Lu Junyu.

The matter was urgent. After simply packing up the luggage, the five horses galloped away. The four guards including Yu Hua and Lu Junyu quickly left Yulin and rushed to Yancheng.

After these days of training, Yu Hua's horse riding skills have grown steadily. Although he can't compare to Lu Junyu, he at least knows how to control a horse.

To be fair, if it weren't for the fact that horseback riding requires the cooperation of humans and horses, and if it was replaced by mechanical equipment, Yu Hua's operating skills would have been perfected long ago.

It's no joke that the thinking in the head approximates a physical system.

Time passed, and at eleven o'clock in the middle of the night, Yu Hua and the five changed horses three times in a row at the Red Army garrison in various county towns, and finally arrived at the Yancheng Military Industry Bureau.

Things did not exceed his expectations. The reason why Chen Kang called him to return quickly was about the production of weapons.

……

One o'clock.

Military Industry Bureau, cave conference room.

The incandescent lamp hanging at 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 team are sitting in the corresponding positions, with a solemn atmosphere.

"Today, August [-], to make a long story short, according to the news from the comrades in the north, the Pingjin area has been occupied the day before yesterday, and Song followed Nanjing's order to retreat to the south. Bombed by Japanese bombers and then set on fire, it has become a ruin, even worse than the Eight-Power Allied Forces attacking the Yuanmingyuan."

Chen Kang's face was serious and heavy, his eyes looked around the people present, and finally he gave Yu Hua a special look, and slowly announced the latest news about Peking: "In addition, Peking University and Tsinghua University were successively attacked by Japanese troops and have been captured and looted."

The private Nankai University has become the most influential education base in the country due to 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 is a thorn in the eyes, and it is a thorn in the flesh. It is necessary to carry out the most thorough humane destruction. After the city of Tianjin was broken, the Japanese army went straight to the private Nankai University as soon as possible, mobilized bombers to bomb, and then set it on fire. .

Fortunately, it was the summer vacation period, and the education of the three schools in the north and south of the Qing Dynasty moved to the south in advance. There were no male or female students in the school. Otherwise...

The atmosphere became more and more dignified, and everyone present was angered. They gritted their teeth at the atrocities of the Japanese army. When Chen Kang's last words fell, everyone's eyes turned to Zhuang Qianding and Yu Hua.

Because Tsinghua is Yu Hua's alma mater, where Zhuang Qianding teaches.

"Don't worry, I'm fine."

Zhuang Qianding took a deep breath. Although he was angry, he remained calm. Anger could not change anything. Naturally, Tsinghua would not be spared from the fall of Pingjin, which was expected.

"I'm fine, don't worry."

Yu Hua responded: "I believe that China will win, and the Japanese invaders will eventually pay the price of invading China, using their land and their blood, and this is exactly what we are going to do."

There is nothing to be angry about, and nothing to suffer.

Everything will eventually be paid for in blood.

"Given that the Japanese invaders are likely to invade the south after capturing Pingjin, and the superiors are in contact with Nanjing, our Red Army troops will soon be changed to the National Revolutionary Army. Production supplies troops."

Seeing Zhuang Qianding and Yu Hua's reaction, Chen Kang nodded, feeling a little relieved, and continued: "Professor Zhuang, I need data from the highest science and technology team. First of all, how much can I transfer without affecting the wartime production plan? production capacity to increase the production of various weapons and ammunition, and secondly, how long will the test furnace and Yulin Steel Plant be completed and put into production.”
