Half an hour later, Yan Fusheng, Feng Xiaochen, and Ning Mo were already sitting in the small conference room of the Pinghe Power Plant, and sitting opposite them were Ge Jiaming, deputy director of production and chief engineer of the Pinghe Power Plant, Zhao Shuping, deputy chief engineer in charge of maintenance work, and Li Li, deputy chief of the biotechnology department, and Tian Gaofeng, who had just rushed back after hearing the news. As for the deputy factory director Hu Shuhui, whom Yan Fusheng first contacted www.biquge.info because he was in charge of logistics work, he sat in a corner here.

Hearing Hu Shuhui's report that an engineer from a coldwater mine claimed to know how to solve the problem of a malfunction of imported generator sets, Ge Jiaming was overjoyed and asked him to immediately notify the other party to come to the power plant for a consultation without saying a word. When they met, Ge Jiaming mistook Yan Fusheng for the engineer, and only after a few words of greeting did he know that he had made a mistake. When he saw Feng Xiaochen's young face, Ge Jiaming almost lost his temper.

Is there any mistake in this Hu Shuhui, he has been making such a young man for himself for a long time, and he still claims to be an engineer. Looking at his age, it is estimated that he has not graduated from college yet, and he dares to go to the power plant to make nonsense.

Feng Xiaochen said that Stellite alloy is a kind of wear- and corrosion-resistant metal material, which is often used to make industrial parts that can adapt to various harsh working conditions. The steam turbine blades in the generator set work in the high-temperature water vapor environment all year round, and are very seriously affected by steam erosion and water erosion.

The four 250 MW generator sets imported by Pinghe Power Plant from Jiulin Company used this process to weld Stellite cemented carbide on the low-pressure final blades as a waterproof and corrosion material. During an overhaul of one of the units, the plant's technicians found that many of the alloy sheets of the final blades on the turbine side were damaged to varying degrees, some of them were cracked on the surface, and some of them were simply peeled off, and if not remedied in time, they were in danger of falling off.

The steam turbine is a high-speed equipment, and the detachment of alloy sheets in the steam turbine is a very serious problem, which will cause damage to the internal parts. Even if the danger of falling off is not mentioned, cracks in the waterproof etching alloy sheet will cause the base metal of the blade to be corroded due to the loss of protection, affecting the service life.

In the face of this situation, of course, the power plant could not calm down, so it urgently contacted Jiulin Company and asked them to send technicians to the power plant to assist in solving the problem. Jiulin Company sent two technicians, who were the two Feng Xiaochen they had seen in the restaurant today, one was named Hideo Muto and the other was Abeyue. Two Japanese technicians came to the Pinghe Power Plant with a bunch of testing equipment to inspect the steam turbine that had been disassembled, and finally confirmed that the cracks did exist, and some of the cracks had extended to the fusion line welded with the base metal, and the situation was quite serious.

However, there was a disagreement on how to deal with these cracks and strippings. The Japanese side resolutely stated that the reason for this situation was that the Chinese side used it inappropriately, put forward reasons such as too frequent starts and stops, poor water quality, and demanded that the Chinese side bear the cost of repairs, and also offered a sky-high price.

Of course, the Pinghe power plant is not a soft persimmon, they said that they are operating in accordance with normal specifications, and do not exceed the requirements of Jiulin Company, in this case, there is a problem with the blade, obviously the quality of the other party's products is not up to standard. They demanded that Jiulin help repair these defects free of charge, and also pay a certain amount of downtime damages.

The positions of the two sides are very different, so naturally they cannot reach an agreement, and the issue of maintenance has been delayed in this way. Jiulin Company is not in a hurry, and it has no effect on them anyway. The Pinghe Power Plant can't stand it, one unit is stopped there and cannot be restored, and there are other units that also have hidden dangers, and I don't know when the shutdown accident will occur.

Ge Jiaming, as the chief engineer, is facing the most pressure. He gathered the technicians of the whole plant, and also invited several experts through the Ministry of Electric Power to jointly consult the blades, trying to find evidence to prove that the responsibility lies with the Japanese side. But the problem is that the steam turbine blade process produced in China in the past is very different from the process of Jiulin Company, which is also the welding of Stellite alloy sheets, and Jiulin Company uses the argon arc welding process, while the domestic brazing process is generally used, the two are not the same thing, and the domestic experience cannot be copied.

was in a stalemate with the Japanese side, and suddenly heard that someone knew about the Stellite alloy sheet, and volunteered to come to help, how could Ge Jiaming not be happy. His current mentality is a typical rush to the doctor, although he can't believe that there will be a chance of pie falling from the sky, but when he hears this kind of news, he still has to give it a try. But who would have thought that the group of people introduced by Hu Shuhui were too unreliable, one was old, two were young, the old one was a big old man from a mining background, and he didn't understand any technology, but the self-proclaimed engineer was a young man who didn't have a few hairs on his chin.

"It was you who told Director Hu that you knew about the Stelli alloy sheet, how did you know?" Ge Jiaming asked Feng Xiaochen angrily. Everyone has already come, and one of them is the deputy mine manager of Lengshui Mine, and Ge Jiaming is inconvenient to turn his face directly, so he can only patiently talk to the other party. He had already thought about it, said a few words casually, and when the other party began to talk nonsense, he raised his legs and left, at least it was considered to have given the other party a chance, and the other party had nothing to say.

Feng Xiaochen shook his head and said, "Actually, I don't know. I just heard that there were some failures in the units introduced by the Pinghe Power Plant, and I guessed that there was a problem with the Stellite alloy sheet. ”

"Guess?" Ge Jiaming sneered, "Just when you hear that the generator set is out of order, you will guess that the Stellite alloy sheet is really a god." Do you know how many types of faults there are in the generator set?"

"I don't know. Feng Xiaochen said, "However, if there is a problem with the crew of Jiulin Company, there is a good chance that it is a problem in this regard." ”

"Why?" asked Ge Jiaming with some suspicion. With his rich experience, it is impossible for him to think of the problem of alloy sheet at once, after all, there are many places where the generator set may fail, and this kind of Stellite alloy sheet has a wide range of cracks, but he has seen it for the first time. But if you want to say that Feng Xiaochen is talking nonsense, he is accurate again, this time the matter is indeed a problem of alloy sheets.

Feng Xiaochen said: "Jiulin's 250 MW generator set is a very mature technology, and there have been no serious problems in the past. The four units of the Pinghe power plant have only been in operation for four years, and the probability of failure at this time is very small. But I heard that the Pinghe Power Plant had hired two Japanese benzene technicians, and they had been in Pinghe for a long time, so I speculated that the matter of alloy sheets would be so troublesome. ”

"But...... How did you come up with this?" Zhao Shuping, deputy chief engineer, asked anxiously, the reason Feng Xiaochen said was really insufficient. Jiulin's 250 MW units are of stable quality, which is a well-known thing. But why is it always a problem with the alloy sheet if it fails? I have never heard of any problems with the alloy sheet in the past.

Everyone was staring at Feng Xiaochen, wanting to hear his explanation, but Feng Xiaochen smiled slightly and turned his head to Yan Fusheng. Yan Fusheng smiled awkwardly at everyone, and was also silent, and started a dumb riddle with everyone.

"Old Hu, what do you mean by a few comrades from the Lengshui Mine?" Ge Jiaming was anxious and asked Hu Shuhui, who was sitting on the side playing soy sauce.

Hu Shuhui smiled bitterly and said: "Lao Ge, you know, a few days ago, Mine Chief Yan came to our factory and wanted to ask our factory to help coordinate some power supply indicators, and then ...... Aren't we nervous about the indicators......"

"Power supply index?" Ge Jiaming frowned, thought about it, and said to Yan Fusheng: "Mine Chief Yan, you want power supply indicators, this matter is easy to discuss." Now the matter of our factory burning eyebrows is the maintenance problem of this unit, and I will not hide it from all of you, what Comrade Xiao Feng said just now is indeed the truth, and the problem of our current unit is on the alloy sheet. It's just that I don't understand, why did Comrade Xiao Feng think of this all of a sudden?"

Yan Fusheng smiled and said to Feng Xiaochen: "Xiao Feng, you tell Director Ge, don't sell Guanzi." ”

"I didn't sell it. Feng Xiaochen smiled disguised and said. What he did just now was really waiting for the power plant to speak. I am here to ask for power supply indicators, not to do charity. He used a few words to whet Ge Jiaming's appetite, and now he wants Ge Jiaming to agree to make a deal with them. He told Ge Jiaming about the alloy sheet, and Ge Jiaming had to solve some power supply indicators for them, if the other party was unwilling to exchange, then he would rather not squeak.

Will the other party not exchange? Feng Xiaochen was very sure in his heart, knowing that it was impossible for the other party to give up. In the early 80s, no one knew about the dispute between Pinghe Power Plant and Jiulin Company at the time, but in later generations, some people disclosed it one after another, and said a lot of details, and Feng Xiaochen also knew about it. He understood that this was the time when the Pinghe Power Plant was most entangled, and the plant had already planned to give in to the Japanese side and pay the maintenance fee in exchange for the Japanese side to help complete the maintenance work as soon as possible. Ge Jiaming and the others are already making their last efforts, and if these efforts are not effective, they can only bow their heads.

At this time, Feng Xiaochen made a trick to reveal a little bit of tone to them, can they not be used as a lifesaver to hold on desperately?

"Director Ge, I was just not sure if my guess was right just now, so I can't say more. Since you said that the problem is indeed on the alloy sheet, then I was right in my guess. In fact, I can guess this, and there is no special reason, because I have read a piece of information that a serious accident occurred in a Jiulin generator set at the Nippon Chiga Power Plant last year, and the cause was the stripping of the Stellite alloy sheet. During the repair, the technicians also found a large number of alloy cracks, and Jiulin Company made a large amount of compensation for this. ”

Feng Xiaochen spoke eloquently. Ge Jiaming, Zhao Shuping, and others' eyes were already round. (To be continued.) )
