When Jiang Yan explained to everyone, all the people gathered around, and after the last time the fifth master flew test, there was a problem, and it was immediately sealed, and it was not allowed to go to the sky again.

This fifth master is the second time it has gone to heaven with illness.

When everyone looked at the few parts on Jiang Yan's left hand side with obvious bump marks, everyone regretted it a little in their hearts.

If they had known that this was the case, they didn't need to invite Jiang Yan over at all, they only needed to fly this Fifth Master on it again, and then come down, and they would have checked it carefully, maybe they would have been able to check it out!

However, there are no ifs in this life......

"That's the problem, I think we first have to analyze the composition of this part and then find out the problem, but these are the things that the experts are good at."

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

After all, in order to find out the problem of the resonance of the fifth master, everyone has been busy for so long day and night, and everyone has also contributed a lot.

At this time, it is also time for them to behave as well.

Again, after a few days of tossing, Jiang Yan is also really tired.

Director Shen, they didn't think so much, analyzing the difference in the materials of these parts, this is really not a difficult thing for them, there is no need to keep pulling Jiang Yan to participate.

Moreover, Jiang Yan came from Sijiu City since he started, and in the past two days, he has basically not rested much, this person has already found out the problem, and it is time for the family to take a rest.

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

In fact, you don't need to go to the laboratory to analyze anything, change the parts on the first five masters to the second five masters, and fly a few more times, and you can immediately detect whether this is a problem.

However, there is no need for Jiang Yan to say this, naturally someone put forward this opinion.

So the second Wuye, which replaced the parts, went through several flight tests, and it was completely determined that it was because of this part that caused the aircraft resonance.

Unconsciously, Jiang Yan has been here in Nanfei for more than half a month, the drawings of the parts have been finalized after repeated experiments, and then they are ready to produce.

They know that in the field of this material, Jiang Yan can be regarded as a first-class person, after their testing and comparison, the alloy used in the production of those parts is one of the alloys invented by Jiang Yan, and the alloy invented by Jiang Yan is even better than his.

Knowing this situation, they immediately united, saying that they would let Jiang Yan spit out something more, Nancheng Iron and Steel Plant was the factory they chose, and they wanted Jiang Yan to guide production.

Nancheng Iron and Steel Plant, founded in 1958, is a key steel complex in JX Province, the factory is located in the beautiful Qingshan Lake District, the current steel plant has about 5,000 employees, as far as the country's steel mills are not as good as other steel plants in the north, but in the country is also a number of enterprises, but due to the late construction of the plant, the production of products is more popular, but now the country is short of steel, and belongs to the special effects, the benefits of the steel plant is still quite good, It's just that it has never had its own special products.

For Jiang Yan's name, although it is relatively secret, but it is thunderous in the steel plant, because Du Weiguo, the director of Nangang, has also heard of it, and he wanted to invite him to come over for guidance very early, but he applied several times without success.

It happened that Jiang Yan came to Nanfei this time, and Dean Tang proposed to let Nangang produce the steel needed for the aircraft nearby, after Director Du learned the news, the nose of the United States almost bubbled, and I heard that Jiang Yan personally guided, this time Director Du couldn't sit still, just after the determination of the next morning, Director Du drove to Nanfei early.

"Xiao Jiang, this is Comrade Du Weiguo from Nancheng Iron and Steel Plant, and the alloy production of our accessories is produced by their steel factory." As soon as Dean Tang and Jiang Yan went downstairs together, they saw Du Weiguo waiting downstairs.

Seeing this product arrive so early, Dean Tang's heart was tired for a while, this guy was too anxious, but this greasy was crooked, Dean Tang still introduced it to Jiang Yan.

"It's Mr. Jiang! You're really a young talent, and you've heard of your name for a long time. This Du Weiguo didn't wait for Dean Tang's introduction, he came to Jiang Yan with this brisk step, holding Jiang Yan's hand with both hands, which was quite enthusiastic.

"Director Du, it's been awarded, it's been awarded, you still call me Xiao Jiang!" Jiang Yan opened his mouth embarrassedly, and by the way, he also pulled out his hand, Jiang Yan is really a little unaccustomed to his enthusiasm, and Jiang Yan is really a little unaccustomed to adding a fifty-year-old person of the same level as himself to call himself Mr. Jiang.

"Okay, Lao Du, I'll be cheeky and call you Xiao Jiang." Du Weiguo hurriedly got down the slope and got off the donkey's opening.

And then there is the little ginger, not more than the foot ginger, this relationship is not closer, no.

"Okay, okay, Lao Du, don't get tired of being here, hurry up and take us to your factory, Xiao Jiang's time is quite tight." Dean Tang opened his mouth with a displeased expression.

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

"You can't sit in this car, so sit in the car and lead the way, and we will follow behind." Dean Tang opened his mouth and pointed to the two cars parked under the office building.

Du Weiguo followed Dean Tang's fingers and looked at the two cars parked there, and then looked at Jiang Yan and the people who followed behind Dean Tang, and immediately understood, and did not refute, and directly got into the car and led the way in front.

The car quickly drove out of Nanfei, and after about half an hour, it came to Nancheng Iron and Steel Plant.

After getting off the bus, through the introduction of Director Du, Jiang Yan knew that the Nancheng Iron and Steel Plant was not as big as the Red Star Rolling Mill where he was before, but Jiang Yan from later generations knew that this Nancheng Iron and Steel Plant was one of the top 500 in China in later generations.

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

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

"Seagull brand" grade II rebar and "Changli" plane spring flat steel have won the national metallurgical product physical quality "Golden Cup Award", Seagull brand ribbed steel bar, round steel, angle steel, strip steel, welded pipe won the "national quality stable qualified product" award, the products sell well all over the country, and exported to more than a dozen countries and regions in the world.

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