"Can I see where the steel plates are torn?" Feng Xiaochen asked.

"Please look, Director Feng." Quan Jiancai said.

Several people came to the clamping truck to see where the steel plate of the hydraulic rod support arm was torn. Feng Xiaochen carefully observed the color of the fracture, the metal twist and stretching, and then reached out to touch the various parts, and then said to Quan Jiancai and others: "This is a high-strength weldable structural steel, and the yield strength should be above 500 megapas. If our stator weight is 325 tons, according to the existing clamping method and train running speed, theoretically the steel plate will not be overloaded and tear."

"This is also something we can't make sure of." Quan Jiancai said. He was a little distrustful of Feng Xiaochen just now, thinking that even if this deputy director knew a little skill, he might be able to achieve the basics and had no reference value. When he heard Feng Xiaochen say such words, he couldn't help but look at Feng Xiaochen a few times, and his attitude towards speaking became more equal.

"We judged that this part of the supporting arm steel plate may have defects in advance. It may be because there is a problem with the heat treatment after forging and there is a great residual stress. The stator repeatedly squeezes the component during transportation, resulting in metal fatigue, resulting in tearing." Wang Zhihua said.

Feng Xiaochen asked: "How is the situation on the other side?"

"We have seen that the steel plate has not deformed and the surface has not cracked slightly, so there should be no problem." Quan Jiancai said.

Feng Xiaochen said: "Since that's the case, I think the tearing part can be completely welded and repaired, and then welded a few reinforcement ribs next to it to disperse stress. At least it can ensure that the stator will not tear and loose again before being transported to the nearest large station. Now we should not wait like this, but we must start repairing immediately."

Quan Jiancai looked at the huge stator and said, "We may also need to do a force analysis to see how much impact the hydraulic rod support arm will be subjected to when the vehicle speed is maintained at 40 kilometers, and whether welding repair can ensure the strength requirements. If there are problems in the design of the clamp truck and the stress distribution is unreasonable, even if the welding is done, it will crack soon."

"I agree with this opinion." Feng Xiaochen said.

"So, Director Feng, can you do this kind of stress analysis?" Quan Jiancai asked again.

Feng Xiaochen said: "I can do part of it, but I can't ensure the correctness. It would be better if someone helped me to get the lower limit."

"This is no problem, I can check it out for you." Quan Jiancai said. He pointed at Wang Zhihua and Ou Guisheng with his fingers and said, "Neither Wang Gong nor Director Ou are engaged in mechanics. I just said to do a force analysis, and they said they can't help. Now, if Director Feng can do part of it, I will have confidence."

"The question now is how much time the railway department can give us." Ou Guisheng reminded, "Now Director Li and Director Shang and others are arguing with the people in the railway department."

"Let's go over and ask." Feng Xiaochen suggested.

"Well, go over and ask." Ou Guisheng said.

Quan Jiancai and Wang Zhihua did not go there, but stayed next to the clamp truck, took out a tape measure and started to measure, preparing for the subsequent stress analysis. Feng Xiaochen followed Ou Guisheng to the quarreling group. Ou Guisheng shouted to the deputy director of the Ministry of Machinery, named Li Guoxing, "Director Li, a comrade from Linbei Heavy Machinery said he wanted to ask about the restoration plan."

Everyone was quarreling hard, and when they saw Ou Guisheng step forward and interrupted, they all stopped and took the opportunity to rest their throats. At the same time, they also sorted out their thoughts to fight again. Li Guoxing turned his head and looked at him. Seeing that the person Ou Guisheng brought was extremely young, he felt unhappy and asked angrily: "Is the comrade Lin Beizhongji you are talking about? What is he doing?"

"Is it Director Li? Let me introduce myself. I am a cadre of the Metallurgical Bureau of the State Economic Commission and the deputy director of the Production Department of Linbei Heavy Machinery. My name is Feng Xiaochen." Feng Xiaochen said. He also knew that his age was a flaw, so he was discriminated against more than once or twice.

"Deputy Director? How could there be such a young deputy director?" Li Guoxing muttered.

"Linbei Heavy Machinery? What did you say you are called?" The director of the Ministry of Electric Power, Shang Jinglun, looked at Feng Xiaochen and asked.

"My name is Feng Xiaochen." Feng Xiaochen said.

"Feng Xiaochen? Are you the Feng Xiaochen who has been to Pinghe Power Plant?" Shang Jinglun asked.

Feng Xiaochen was stunned for a moment, then nodded and said, "That's right, I just came back from Pinghe Power Plant."

"So it's you!" Shang Jinglun's face showed a look of surprise, "I heard from Lao Ge of Pinghe Power Plant that you convinced the two inspectors of Jiulin Company and forced them to admit that the peeling of the Sitaili alloy sheet of the motor was a quality issue, saving them a lot of repair costs. How could you be here?"

"What, you did that matter at Pinghe Power Plant?" Ou Guisheng also asked in surprise.

Pinghe Power Plant is an enterprise under the Ministry of Electric Power. The Jiulin Motor Corrosion Anti-Shape is also known to the Ministry of Electric Power. Pinghe Power Plant previously reported to the Ministry of Electric Power, asking if the Japanese side insists that the responsibility lies with China, can we accept this result first and pay a fee to ensure the motor is repaired quickly. After Feng Xiaochen helped them defeat Hideo Muto and his party, Pinghe Power Plant made another report to the Ministry of Electric Power, which also specifically mentioned the important role Feng Xiaochen from Linbei Heavy Machinery played in this matter.

Shang Jinglun is the director in charge of motor production, so he naturally pays more attention to this information. When Feng Xiaochen was dealing with the Riben people, Shang Jinglun was organizing the loading of a 600,000-kilowatt stator at the Longshan Motor Factory. After hearing this news, he was very happy and introduced it to Ou Guisheng and others. What they never expected was that they actually met Feng Xiaochen, a hero, in this place.

"Director Xiao Feng, what did you say just now? Do you want to ask about the repair plan?" Shang Jinglun brought the topic back to the topic. Tian Xing and others were still standing opposite them waiting to continue the argument. Now is not the time for him to discuss gossip with Feng Xiaochen. However, because he knew Feng Xiaochen's actions at Pinghe Power Plant, Shang Jinglun was obviously much more polite to Feng Xiaochen, and even Li Guoxing was not inconvenient to attack him again.

Feng Xiaochen said: "Yes, Director Shang and Director Li, I want to inquire about what our solution is now."

"Of course, you should unload the stator truck immediately, drive away the clamp truck, and restore the full opening of the Jinglong Line." Tian Xing rushed to say.

"This is impossible. Whoever dares to drive the stator on the train is a national sinner!" Li Guoxing was not outdone and shouted loudly.

"Two, two, don't worry first." Feng Xiaochen quickly raised his hand to stop both parties, and then asked Tian Xing with a smile: "You are Director Tian? It's a fact that the Jinglong line is blocked. I take the liberty to ask, what is the maximum blockage time you can tolerate?"

"Can we tolerate it? We can't tolerate it for a minute!" Tian Xing said angrily.

Feng Xiaochen smiled slightly and said, "Director Tian, ​​don't say such useless words. You have been quarreling for more than half an hour just now. I can guarantee that if you both sides do not reach a consensus, at least they will have to argue for another hour, so it is meaningless to say that you cannot tolerate a minute."

"Uh..." Tian Xing was choked all of a sudden. He said that he would not tolerate it for a minute, of course, just a gesture. In fact, facing the tough attitude of the Ministry of Machinery and the Ministry of Electric Power, he could only endure it for more than one minute, one hour, or even ten hours. Not to mention that there were only 4 people here in total, and the train drivers, the furnaces, etc., which were not the opponents of so many people in Longshan Motor Factory. Even if all the people from Longshan Motor Factory were out of the way, Tian Xing did not have the courage to push the stator down from the clamp truck. As Li Guoxing warned, it is difficult to bear the responsibility for anyone who dared to unload the stator.

"Director Feng, what do you mean?" A military representative in military uniform spoke. He heard some profound meaning in Feng Xiaochen's words, and felt that this young man might as well make a decision after he finished speaking.

Feng Xiaochen said: "Just now, Director Ou, Wang and I have discussed it. We think that we can repair the cracked arm through welding to ensure that the stator will not be displaced or overturned before being transported to the next large station. But we need some time, so I would like to ask all the leaders, how much time can you give us to complete this repair task at most?"

"Can you do a site repair?" Tian Xing asked in disbelief, "How sure are you?"

Feng Xiaochen said frankly: "We are only 50% sure, but we can give it a try."

"Do you use your existing manpower?" Li Guoxing asked.

Feng Xiaochen shook his head and said, "I just asked the General Chief Engineer. He said that this time he escorted the stator to Hezhou Power Plant, and there were no welding installation matters, so the only ones who escorted the truck were porters, no welders. I had asked someone to go to the train behind to ask if there were excellent welders. If three excellent welders can be found, and if we can find welding equipment around, we are 50% sure we can repair the support arm."

"A 50% sure is worth a try," said Li Guoxing. "Our original idea was to ask Longshan Motor Factory to send someone to bring equipment here immediately, but it would take at least 2 days for them to take the train and then transfer to the car here."

"This is something we absolutely cannot accept!" Tian Xing said decisively, and then he turned to Feng Xiaochen and asked, "Director Feng, how long does it take according to your repair plan?"

Feng Xiaochen said: "It depends on whether welders and welding equipment can be found. If we can find it, we can only complete the repair in a maximum of 12 hours. By the way, the on-site electricity supply must also be guaranteed."
