Siheyuan starts from a good life

When Jiang Yan explained to everyone, everyone gathered around. After the last test flight of the Fifth Master, something went wrong and it was immediately sealed and never flew into the sky again.

This Fifth Master is the second time it has gone to heaven with a disease.

When everyone looked at the parts with obvious knock marks on Jiang Yan's left hand side, everyone felt a little regretful.

If they had known that this was the case, there would have been no need to invite Jiang Yan over. They only needed to fly the Fifth Master one more time, and then come down. They would check it more carefully, and maybe they would be able to check it out!

However, there is no if in this life...

"This is the problem. I think we first need to analyze the composition of this part and then find out the problem, but these are things that experts are good at."

Jiang Yan looked at the experts and professors surrounding him. He knew that at this time, he should share the credit.

After all, everyone has been working day and night to find out the resonance problem of this Fifth Master, and everyone has contributed a lot.

At this time, it's time for them to show off too.

Another thing is that Jiang Yan is really tired from all the hard work these days.

Director Shen and the others didn't think too much about it. Analyzing the differences in the materials of these parts was really not a difficult task for them. There was no need to keep involving Jiang Yan.

Moreover, Jiang Yan has basically not had much rest in the past two days since he came from Sijiu City. This person has figured out the problem and it is time for him to take a rest.

Therefore, Director Shen handed over the task of analyzing the materials to these experts and professors headed by General Engineer Lu.

In fact, there is no need to conduct laboratory analysis or anything. Just replace the parts on the first Wuye with the second Wuye, and fly it a few times, and you can immediately detect whether this is the problem.

But there was no need for Jiang Yan to say this. Someone naturally raised this opinion.

So the second Wuye had its parts replaced, and after several more flight tests, it was completely determined that it was this part that caused the aircraft resonance.

Unknowingly, Jiang Yan had been here in Nanfei for more than half a month. The drawings of the parts had been finalized after repeated experiments, and they were ready for production. Originally, Jiang Yan wanted to leave when he found a problem, but was stopped by Dean Tang and Mr. Lu. Gong stayed for the Joint Festival, and he managed to get Jiang Yan over as a joke, so he had to make good use of it if he didn't stay.

They knew that Jiang Yan was a top-notch figure in the field of materials. After their tests and comparisons, they found that the alloys used to produce those parts were among the alloys invented by Jiang Yan. One of them, and the alloy invented by Jiang Yan was even better than his.

After knowing this situation, they immediately united and asked Jiang Yan to say something. Nancheng Steel Plant was the factory they selected, and they wanted Jiang Yan to guide production.

Nancheng Steel Plant, founded in 1958, is a key steel joint enterprise in JX Province. The factory is located in the beautiful Qingshan Lake District. Currently, the steel plant has about 5000 employees. As far as steel plants in the country are concerned, it is not as good as other steel plants in the north. The steel plant is also one of the few enterprises in the country. However, because the plant was built relatively late and the products it produces are relatively popular, the country is short of steel these days, and it is a special product. The efficiency of the steel plant is still quite good. , but it has never had its own special products.

Although Jiang Yan's name is relatively confidential, it is well known within the steel plant. Since Du Weiguo, the director of Nanjing Iron and Steel Co., Ltd., has also heard about it for a long time, he has wanted to invite him for guidance for a long time, but he has applied several times without success.

It happened that this time Jiang Yan came to Nanjing, and Director Tang proposed that Nanjing Iron and Steel Co., Ltd. produce the steel needed for the aircraft nearby. After Director Du knew the news, Mei's nose almost bubbled, and when he heard that Jiang Yan was personally giving guidance, Director Du couldn't sit still at this time. As soon as the confirmation was confirmed, Director Du drove to Nanfei early the next morning.

"Xiao Jiang, this is Comrade Du Weiguo from Nancheng Steel Plant. The alloy production of our accessories is produced by their steel plant." Dean Tang and Jiang Yan had just gone downstairs when they saw Du Weiguo waiting downstairs.

Seeing this guy arriving so early, Dean Tang felt a twinge of boredom in his heart. This guy was too impatient, but because of this, Dean Tang still introduced him to Jiang Yan.

"It's Mr. Jiang! You are really a young talent. I have heard about your name for a long time." Du Weiguo didn't wait for Dean Tang to introduce him, and walked quickly to Jiang Yan, holding Jiang Yan's hand with both hands. Hands, that's quite enthusiastic.

"Director Du, thank you, thank you, you should call me Xiao Jiang!" Jiang Yan said embarrassedly, and took out his hand at the same time. Jiang Yan was really uncomfortable with his enthusiasm. Jiang Yan is really not used to it, and when a fifty-year-old man of the same level as himself calls him Mr. Jiang, Jiang Yan is really not used to it.

"Okay, Lao Du, I will shamelessly call you Xiao Jiang." Du Weiguo hurriedly walked down the slope and spoke.

Furthermore, calling me Xiaojiang is closer than calling me Jiangjiang.

"Okay, okay, Lao Du, we are tired of being here. Take us to your factory quickly. Xiao Jiang is very tight on time." Dean Tang spoke with an unhappy expression.

"Okay, okay, Dean Tang, please, Xiao Jiang, please." Du Weiguo nodded and opened his car door, and enthusiastically invited Jiang Yan and Dean Tang to sit in.

"You can't fit in this car, so you can sit in the car and lead the way, and we will follow behind." Dean Tang said, while pointing at the two cars parked under the office building.

Du Weiguo followed Dean Tang's fingers and looked at the two cars parked there. Then he looked at Jiang Yan and the people following Dean Tang. He understood immediately and got into the car without retorting. Lead the way ahead.

The car quickly drove out of Nanfei, and after about half an hour, it arrived at Nancheng Steel Plant.

After getting off the car, Jiang Yan knew through Director Du's introduction that the Nancheng Steel Plant was not as big as the Hongxing Steel Rolling Plant where he worked before. However, Jiang Yan, who came from a later generation, knew that the Nancheng Steel Plant would be one of the top 500 companies in my country in later generations.

They produce various specifications of rebar, round steel, angle steel, spring flat steel, hot and cold rolled strip steel, automobile leaf springs, welded pipes, etc. It has fully passed ISO9002 quality system certification, and now has 3 ministerial-quality products and 7 provincial-quality products. The rate of high-quality steel products reaches more than 80%, and the double-standard rate of implementing international advanced standards and national standards reaches 92%, forming the brand advantages of two series of "Seagull" construction steel and "Changli" automobile springs.

Among them, "Seagull Brand" Grade II threaded steel bars are among the first batch of inspection-free products and key protection grade products in JX Province. In 2001, it was approved as an inspection-free product by the State Bureau of Quality and Technical Supervision, and was registered in Hong Kong as an inspection-free product; "Changli" automotive leaf spring series products were listed among the first batch of "recommended products" in the country by the User Committee of the my country Quality Management Association and the Trade Committee of the Automobile Industry Association. commodity".

"Seagull brand" grade 2 threaded steel bars and "Changli brand" flat spring flat steel both won the "Golden Cup Award" for the physical quality of metallurgical products in the country. Seagull brand ribbed steel bars, round steel, angle steel, strip steel, and welded pipes won the "National Quality Stability Award". Qualified Products" honor, the products sell well all over the country and are exported to more than a dozen countries and regions in the world.

The larger Red Star Steel Rolling Mill, which is now more technologically advanced, has indeed disappeared in later generations. The contrast between the two is quite large.
