"Leader, party members are all atheists!"

"Atheists, can't they have ardent expectations and good wishes?" Chen Mingshan asked Xie Kai with a smile, "We can't afford to fail." ”

If there is a problem in the trial production of the large press, or the pressure is not reached, in the die casting process, it is not possible to provide enough pressure to form the turbofan disc at one time, which will have a serious impact on many subsequent projects.

If the pressure is not enough, what can be done is multiple die casting.

Die forging is not free forging, multiple die casting, may not be able to achieve the effect, must be formed at one time.

The main frame beams and landing gear of the Yun-10, the turbofan engine that bears high temperature and high pressure, and the main girder of the Super 7 fighter all need to be die-cast by this large press at one time.

The 65,000-ton large press project has not been determined so far, just because this 45,000-ton large press belongs to the verification machine of the follow-up large press.

"How does your unit consider the 65,000-ton project?" Chen Mingshan asked Xie Kai, "Theoretically, there is no problem with this large press, and the 65,000-ton project is not a problem." ”

He naturally knew that the 404 was waiting for the effect of this big press.

The largest pressure forging machine in China, only the 30,000-ton die forging hydraulic press of Southwest Aluminum, which was made in the sixties, was installed in Southwest Aluminum, which belongs to the third-line project, in 71 years, mainly for domestic fighter jets.

Since then, the state has never engaged in a die forging hydraulic press with a larger tonnage.

On the one hand, the technical strength is not good, and the reserves are insufficient; on the other hand, the cost is too high, and even if it is made, it will not be used.

The country's 65,000-ton large press project is to support Yunshi.

Just because of the lack of technical reserves, the final design was not completely completed.

404 took over, and the 65,000-ton project eventually became 45,000 tons......

Now, the design and production teams naturally want to continue to do it, and the key is that the owner needs to speak.

"Leader, our base, the funds are ready, as for whether to continue to work on this project after the completion of this here, I think we need to wait to see the effect of trial production. Xie Kai knew what Chen Mingshan was worried about.

The mechanical department of Huaqing University and the first and second heavy presses have completed the design of the 65,000-ton press, and they need to be produced to verify whether there is a problem with the design, and there is no problem before it can continue.

The core technology of each larger tonnage press is based on the previous design.

Similarly, the difficulty of a large press, even if the pressure provided by the press is only a few hundred tons, is not a little more difficult.

The accumulation of basic technology is very important.

As long as 404 does not continue to invest money to build larger tonnage presses, many technical designs cannot be verified, and there is no way to continue to design larger tonnage presses.

"How much money do you need?"

Chen Mingshan had to wipe his face and asked Xie Kai how much money 404 was going to invest.

As discussed earlier, the two sides were unable to negotiate because of financial issues.

"The cost will not be less, it depends on the effect. Xie Kai sighed and looked at the big press standing in the middle of the workshop. "Is the tonnage too small? The transmission spindles used by large warships are hundreds of tons at every turn, not to mention that in the 60s, 12,000 tons of free forging on the upper side could forge dozens of tons of alloy steel and 300 tons of ordinary steel ingots. ”

"The 500-ton crane is still in production, don't you see that there is a lot of space reserved on it?" Chen Mingshan glanced at Xie Kai, this matter should not have been explained to him, "What's more, so far, which of your projects needs hundreds of tons of heavy parts?"

Chen Mingshan did not say that even if there are hundreds of tons of heavy parts, only this is enough, and after forging, it may not be able to meet the design requirements.

"Doesn't seem to be?" Xie Kai thought for a moment, it really wasn't that big at the moment. "A large generator rotor or something, it should be usable, right?"

Wind power has not started in China, and it is impossible for them to specialize in this, and the international research has just begun.

For these, Xie Kai is not too interested in getting it.

"How big of a generator can be produced in China?" Chen Mingshan asked Xie Kai, his face was calm, "we have a big press, and they will start to challenge the design of a larger generator." When the design came out, the 65,000-ton press was built again. ”

Seems to be the truth?

When the core manufacturing capability goes up, the design capability will be improved.

Hearing this, Xie Kai always felt that something was wrong, and he couldn't understand it for a while.

He forgot that as he became more and more aware of the domestic industrial system, he learned that the domestic design capability was not as bad as he originally thought, and many designs could not be realized because of the problems of materials and processes could not be solved.

Of course, some design capabilities are really not good, and because of the limitations of materials, processes and other issues, it is impossible to produce and improve, and the original design is used as the basis to challenge the stronger manufacturing strength.

Until the first decade of the 21st century, several domestic free forging presses of more than 15,000 tons were completed and put into operation, and 40,000 tons and 80,000 tons of die forging machines were put into operation one after another.

C919 large aircraft, Y-20 transport aircraft, J-20 stealth fighter......

The Varyag aircraft carrier was commissioned, the 001 aircraft carrier was launched, and the 002 aircraft carrier continued to be built......

The world's largest high-speed rail network and the most stable high-speed rail technology......

1000 MW half-speed nuclear power rotor solution, therefore, 1000 MW nuclear power technology solved, 1100 MW nuclear power half-speed rotor mass manufacturing, 1400 MW nuclear power half-speed rotor process breakthrough......

Then, the US imperialists were unhappy, and a man named Trump became the boss of the US imperialists, and then regarded China as the number one enemy, and wanted to repeat the old tricks to drag down the Soviet Union.

And so the trade war began......

"Xie Kai, Xie Kai ......" Seeing Xie Kai distracted, Chen Mingshan called him several times, he was very curious, Xie Kai was smiling, as if he had become a fool.

Xie Kai was a little embarrassed and thought too far.

The one in front of me is only 40,000 tons, and the free forging has not yet broken through.

"Leader, why don't I change my major?" Xie Kai didn't hear what Chen Mingshan said, and tentatively changed the topic, "Understand the technology, and then determine the direction of your future......"

"......" Chen Mingshan looked at Xie Kai and was angry for a while.

You don't want to turn professional and mind my, anyway, you've given up on the idea of making you a good mechanical designer.

This is Chen Mingshan's reluctant decision.

For a few days in a row, Xie Kai didn't care about Zheng Yucheng and how they arranged the switch manufacturer, so he stayed in the forging workshop of the Xinyue factory and followed Chen Mingshan to understand the structure of the entire large press.

What you learn from books is never as good as seeing the top technology of this kind of mechanical manufacturing on the spot, not to mention the explanation of the chief engineer?

Two days before the test machine, Minister Shen Hong arrived, and looking at this standing big press, the old man's eyes were red.

On the first day of the test, Long Yaohua and Li Mingshan, who were carrying two gold stars on their shoulders, appeared at the same time, they didn't even pay attention to Xie Kai's sycophants, and in front of the big press that was more than ten times higher than them, they kept asking Chen Mingshan and Chu Guorong and other core engineers, and there was only one meaning in the words - whether the key forging process facing the aero engine now could be effectively solved and the structural strength could be improved.

After receiving an affirmative answer, the two old men actually ignored their image at all, hugged each other and wept.

"General, general, there are many people, pay attention to the image......" Xie Kai couldn't stand it anymore and reminded the two bigwigs.

However, his kindness was not rewarded.

"Get out!"

The two old men disregarded the image and told Xie Kai to get out.

Xie Kai, who was speechless, could only pouting and turned around to leave.

"Come back!" Li Mingshan waited for Xie Kai to walk more than ten meters away, and then stopped him.

"Didn't they all tell me to fuck off. Chief, you continue to ......" Xie Kai came back slowly, and Long Yaohua was so angry that he almost kicked him.

"Old Dragon is going to let you cut the ribbon......" Li Mingshan said to Xie Kai.

The people around him who heard this all turned their eyes to Xie Kai.

Xie Kai was even more confused.

Just kidding, right?

I came to cut the ribbon for the first 40,000-ton press in China, what a high honor it was, and I trembled with excitement when I thought about it.

Xie Kai was really trembling.

Not excited, but severely frightened!

"First ...... Heads...... This joke ...... "Xie Kai didn't speak neatly.

40,000 tons of press, ribbon cutting, he is a young man, if he goes out and is not drowned by spittle, he will be beaten to death with bricks.

"What's the matter, I'm so excited, how can I carry a heavier burden in the future?" Long Yaohua asked Xie Kai with a smile.

Xie Kai took several deep breaths in a row to calm himself down, and with a bitter face, "Leader, I still want to live for a few more years." ”

"If you want to live a few more years, you have to do this. What an honor, look at it, the old dragon has been given to you!" Li Mingshan also looked at Xie Kai with a smile. "You have contributed a lot to the completion of this big press. ”

"That's Lao Zheng's doing, I just mentioned it casually. Xie Kai calmed down and hurriedly refused, "Lao Zheng is more suitable." So many of our projects are decided by them. ”

The head shook like a rattle.

Xie Kai had never felt like his brain was working so fast.

He understood the reason why Li Mingshan and Long Yaohua did this, this was to completely accept Zheng Yucheng's plan to use him as the successor of 404, which also paved the way for him.

But he also knew that once he really came up, the happy little days in front of him would be gone, and he had to guard against cold arrows at any time.

No matter how many people struggle all their lives, it is impossible to get such honor and status.

"That's a good thing. Anyway, sooner or later, you have to become the leader of 404, it's not bad to adapt to it as soon as possible, isn't it?" Xie Kai told Zheng Yucheng about the matter, and the old guy actually smiled and agreed.

"What a fart!" Xie Kai couldn't help but explode at the old guy.
