"Can I see where the steel plate is torn?" Feng Xiaochen asked. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Director Feng, please take a look. Quan Jiancai said.

Several people came to the clamping car together to inspect the place where the steel plate of the hydraulic rod arm was torn. Feng Xiaochen carefully observed the color, metal twisting and stretching of the fracture, and reached out to touch everywhere, and then said to Quan Jiancai and others: "This is high-strength weldable structural steel, the yield strength should be more than 500 megapascals, if our stator weight is 325 tons, according to the existing clamping method and train running speed, theoretically the steel plate will not be overload torn." ”

"That's where we can't be sure. "Quan Jiancai said. He was still a little distrustful of Feng Xiaochen just now, and felt that even if this deputy director knew a little technology, he might be able to reach the surface, and there was no reference value. When he heard Feng Xiaochen say such a thing, he couldn't help but glance at Feng Xiaochen a few times, and his attitude became more equal.

"We judged that the branch arm steel plate may have been defective in advance, and it may have been a problem with the heat treatment after forging, and there was a large residual stress. The stator repeatedly crushes this part during transport, causing the metal to fatigue and tearing. Wang Zhihua said.

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

"We have seen that the steel plate has not been deformed, and there is no slight cracking on the surface, so there should be no problem. "Quan Jiancai said.

Feng Xiaochen said: "In this case, I think the torn part can be welded and repaired, and then a few stiffeners can be welded next to it to disperse the stress, at least to ensure that the stator will not be torn and loosened again before it is transported to the nearest big station." Instead of waiting, we should start working on the fix right away. ”

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 arm will be subjected to when the speed of the vehicle is maintained at 40 kilometers, and whether the welding repair can ensure the strength requirements." If there is a problem in the design of the clamp cart and the force distribution is not reasonable, even if it is welded, it will soon re-crack. ”

"I agree with this opinion. Feng Xiaochen said.

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

Feng Xiaochen said: "I can do a part, but I can't ensure the correctness, it would be better if someone helped me check the level." ”

"That's fine, I can check it for you. Quan Jiancai said, he pointed at Wang Zhihua and Ou Guisheng with his finger, and said: "Wang Gong and Director Ou are not engaged in mechanics, just now I said to do a force analysis, they said that they can't help." Now, if Director Feng can do part of it, then I have confidence. ”

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

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

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

Quan Jiancai and Wang Zhihua did not go over, but stayed next to the clamp car, took out a tape measure and began to measure to prepare for the follow-up force analysis. Feng Xiaochen followed Ou Guisheng to the person who was arguing, and Ou Guisheng shouted to the deputy director of the Machinery Department named Li Guoxing: "Director Li, there is a comrade from Linbei Heavy Machinery who said that he wanted to ask about the repair plan. ”

Everyone was arguing inextricably, and when they saw Ou Guisheng stepping forward to interrupt, they all stopped, taking the opportunity to rest their throats, and at the same time, they also sorted out their thoughts again in order to fight again. Li Guoxing turned his head to take a look, and when he saw that the person brought by Ou Guisheng was unusually young, he was unhappy in his heart, and asked angrily: "Is he the comrade you are talking about, Lin Bei Heavy Machinery, and what is he doing?"

Let me introduce myself, I am a cadre of the Metallurgical Bureau of the State Economic Commission, and I am also the deputy director of the production department of Linbei Heavy Machinery, my name is Feng Xiaochen. Feng Xiaochen said that he also knew that his age was a hard injury, and he was discriminated against more than once or twice.

"Deputy Director, how can there be such a young Deputy Director?" Li Guoxing muttered.

"Lin Bei Heavy Machinery, what do you say your name is?" The director of the Ministry of Electric Power named Shang Jinglun looked at Feng Xiaochen and asked.

"My name is Feng Xiaochen. Feng Xiaochen said.

"Feng Xiaochen, are you the Feng Xiaochen who went to the Pinghe Power Plant?" asked Shang Jinglun.

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

"It turned out to be you!" Shang Jinglun showed a look of surprise on his face, "I heard Lao Ge of the Pinghe Power Plant say that it was you who persuaded the two inspectors of Jiulin Company to force them to admit that the spalling alloy sheet of the motor was a quality problem, which saved them a lot of maintenance costs." Why are you here?"

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

Pinghe Power Plant is an enterprise under the Ministry of Electric Power, and the Ministry of Electric Power also knows about the peeling of the anti-corrosion chips of Jiulin Motor because it involves a large amount. The Pinghe Power Plant had also sent a report to the Ministry of Electric Power, asking whether it could accept the result first and pay a fee to ensure that the motor was repaired quickly if the Japanese insisted that the responsibility lay with the Chinese side. After Feng Xiaochen helped them defeat Hideo Muto and his party, the Pinghe Power Plant made another report to the Ministry of Electric Power, which also specifically mentioned the important role played by Feng Xiaochen from Linbei Heavy Machinery 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 Japanese people, Shang Jinglun was organizing the loading of 600,000 kilowatts of stator at the Longshan Electric Machinery Factory, and after hearing the news, he felt very happy and introduced it to Ou Guisheng and others. What they never expected was that they actually ran into Feng Xiaochen, a hero, in this place.

"Director Xiao Feng, what did you just say, you want to ask about the repair plan?" Shang Jinglun led the conversation back to the topic, Tian Xing and the others were still standing opposite them waiting to continue the dispute, and now was not the time for him to discuss gossip with Feng Xiaochen. However, because he knew what Feng Xiaochen did in the Pinghe Power Plant, Shang Jinglun's attitude towards Feng Xiaochen was obviously much more polite, and even Li Guoxing was inconvenient to make trouble anymore.

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

"Of course, the stator was immediately unloaded, the clamp car was driven away, and the entire Jinglong line was restored to traffic. Tian Xing hurriedly said.

"This is impossible, whoever dares to move the stator on the car, he is a national sinner!" Li Guoxing did not show weakness and shouted loudly.

"Two, two, don't worry. Feng Xiaochen hurriedly raised his hand to stop the two sides, and then asked Tian Xing with a smile: "You are Director Tian, right? Now that the Jinglong Line is blocked, I take the liberty of asking, what is the longest blocking 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 this kind of useless words, you have been arguing for more than half an hour just now, I dare to guarantee that if you can't reach a consensus, you will have to quarrel for at least another hour, so it is meaningless to say that you can't tolerate it for a minute." ”

"Uh......" Tian Xing was choked up all of a sudden, he said that he would not tolerate it for a minute, of course, it was just an attitude. In fact, in the face of the tough attitude of these people in the Ministry of Machinery and the Ministry of Electricity, he could only endure it for a minute, an hour, or even 10 hours. Not to mention that there were only 4 people on their side, plus a few drivers and stokers who drove the train, they were not the opponents of so many people in Longshan Electric Factory. Even if all the people from Longshan Electric Factory got out of the way, Tian Xing didn't have the courage to push the stator off the clamp cart. As Li Guoxing warned, whoever dares to unload the stator is difficult to bear.

"Director Feng, what do you mean?" a military representative in military uniform spoke, he heard some deep meaning in Feng Xiaochen's words, and felt that he might as well let the young man finish talking before he did something.

Feng Xiaochen said: "Just now, the chief engineer, Director Ou, Wang Gong and I have discussed, we think that the cracked arm can be repaired by welding to ensure that the stator will not be displaced or overturned before being transported to the next big station." But we need some time, so I'd like to ask the leaders, how much time can you give us at most to complete this fix?"

"Can you do on-site restoration?" Tian Xing asked in disbelief, "How sure are you?"

Feng Xiaochen said frankly: "We are only fifty percent sure, but we can give it a try." ”

"Do you want to use the existing manpower?" asked Li Guoxing.

Feng Xiaochen shook his head and said: "I asked the chief engineer just now, and he said that this time he escorted the stator to the Hezhou Power Plant, and did not take into account the welding installation, so there were only porters and no welders who escorted the car." I've just asked people to go to the next train to ask if there are good welders, if we can find three good welders, and if we can find welding equipment around, we are 50% sure that we can fix the arm. ”

"Fifty percent sure, but it's worth a try. Li Guoxing said, "Our original idea was to ask Longshan Electric Machinery Factory to send someone to bring equipment over immediately, but it will take them at least two days to get here by train and then car." ”

"This is absolutely unacceptable to us!" Tian Xing said categorically, and then, he turned to Feng Xiaochen and asked, "Director Feng, according to your repair plan, how much time will it take?"

Feng Xiaochen said: "It depends on whether we can find the welder and welding equipment, if we can find it, we only need 12 hours at most to complete the repair." By the way, the on-site electricity supply must also be guaranteed. ”

"12 hours?" Tian Xing and the representative of the army glanced at each other, then gritted his teeth and said, "If it's only 12 hours, I can promise you for the time being, and you will start repairing it immediately." However, I said that in the front, if you can't solve the problem after 12 hours, I can only ask you to unload the stator. Also, if the Ministry of Railways issues an order to clear the line, we have to do it. (To be continued.) )
