"Pressure 40%! Pressurize, clamp!"

Originally, the work of the large press did not need to be commanded in this way, and the first test machine, using abrasives to suppress the overall turbine disc, was related to the success or failure of the large press, and had to be so careful.

"Hum~"

The hydraulic motor works louder, and the nickel-base superalloy blank in the middle of the mold stretches like dough in all directions as the pressure provided by the large press continues to rise.

A puff of white smoke spreads along the edge of the mold, which is when the high temperature on the surface of the blank touches the mold, and the high temperature cools and condenses the air......

As it stretched, dark red iron filings fell off in all directions.

The original hard-to-machine nickel-based superalloy blank with a thickness of tens of centimeters under the 45,000-ton large press could not prevent this large press from closing the upper and lower molds of the mold, and there was not even a pause in the middle.

"Pressure 80%, pressure hold!"

The pressure is raised, and the situation in the mold that has been closed cannot be seen at all, but there is no material that extends to the outside of the gap in the middle of the mold because it cannot bear the pressure.

"What's going on!" Zheng Yucheng was as anxious as an ant on a hot pot.

As long as the turbine disc is successfully suppressed and meets the requirements, the turbofan eight engine will progress quickly.

"Wait, it's useless to rush. Seeing that this thing is not moving, the material structure in the mold can change a lot. Shen Hong was also anxious, but he was patiently explaining to Zheng Yucheng.

Xie Kai listened with some curiosity on the side, "Minister, it stands to reason that with such a large pressure, you don't need to maintain pressure to refine the grain structure in the process of pressing down, right?"

"Didn't you notice that the diameter of this blank is a bit large?" Chen Mingshan asked Xie Kai.

Xie Kai had already found out.

Although the diameter of the aircraft engine is not small, the turbine disk inside is not small, but the blank is too big, it stands to reason that it should be a cylinder of a very small diameter, slowly pressed down, and the materials that are not so tight in the middle of the powder metallurgy process are strongly pressed together by different temperatures and pressures.

"Test yet. As long as it is successful, the trial production starts, and the trial production process also has to be adjusted constantly, until the end of the trial production and the design requirements are determined, it will be directly pressed with a smaller blank without pressure holding. Chen Mingshan explained.

In order to ensure that the machine does not have problems, they do not want to waste a single piece of material.

If the pressing is not successful, there will be problems with the machine, and the material blank will also be unusable.

Nickel-based superalloys, both in terms of raw materials and the cost of preparation, are extremely high.

The minimum imported kilogram is six or seven hundred, and people don't want to buy as much as you want to provide, and the domestic ones are only at the cost price, which is also 480 a kilogram.

Such a blank is hundreds of kilograms!

"It's on!"

There was another sound of a hydraulic motor, and the closed mold slowly rose, and at the same time as it rose, there was a puff of smoke.

The blank inside the mold is slightly dull in red.

"Succeeded?" Zheng Yucheng asked excitedly.

"Don't worry, wait until you take it out and take a look. Shen Hong was equally excited, but suppressed.

Without seeing the finished product after pressing, who can guarantee success?

The huge steel tongs of the crane moved over, and slowly clamped out the slightly dull red blank in the mold and dropped it to the side.

A group of people excitedly rushed towards the mold that made the air in the entire workshop hot and dry, and the surrounding heat was exuding.

In fact, it is still a plate, but there are raised steps on both sides of the middle, and there is a small round hole in the middle.

A group of technicians gathered around, kept recording the red blanks, and finally reported the data to Chu Guorong.

Chu Guorong read the data, compared the parts blanks, and announced to everyone, "According to the current data, trial production can be carried out, and the results of the physical and chemical analysis of the internal grain structure will take a few days to come out." ”

Zheng Yucheng didn't care about this, just asked, "Is the big press successful?"

"It's a success!" Chu Guorong told him affirmatively with a smile on his face.

"Succeeded......"

Throughout the workshop, a burst of enthusiastic cheers suddenly erupted.

After working hard for so long, I finally succeeded.

"Good, good, good!" Minister Shen Hong excitedly said three good words in a row, but did not say anything else.

"The wheel of history is always spinning forward, and now, it is finally accelerating!" Xie Kai was also excited, in order to cast this large press, he risked his life to direct the casting of the main beam in a high temperature environment......

Now, at last, it's seeing results.

The life span of the Y-10 will be extended several times, the problem of heart disease in the aviation industry will be effectively solved, and even the power system of the Navy's large warships will be improved......

"The successful test of the large press means that our technology in this area has matured...... The achievements are gratifying, and I would like to extend my warm congratulations to everyone!" Minister Shen Hong personally presided over the celebration meeting after the trial production of the large press.

"Whoa, whoa, ......whoa," and the warm applause rang out.

"I guess I'm going to talk about the rest of the story. Xie Kai sighed.

It doesn't make people happy for a while.

"The achievements are all in the past, and we should base ourselves on the present and look to the future. Comrades, our technology is developing, and foreign technology is also developing, and even because we are more experienced and funded, we will develop faster......" Shen Hong stopped the applause, "At present, there is a 30,000-ton die forging machine from Southwest Aluminum, plus this 45,000-ton one, and there are only two,......

How the celebration ended, Xie Kai didn't know.

Anyway, everyone's happiness is gone.

He thought he had nothing to do with himself, but he was told to go to the meeting room of Xinyue Factory.

When I went to the conference room, I saw that they were all bigwigs, but there was no leader of the Xinyue factory, and Tang Zhenhua, the director of the factory, was not present.

Shen Hong, Long Yaohua, Li Mingshan, Chu Guorong and other bigwigs are all in the factory, so Xie Kai keeps guessing what kind of meeting he will have, and he doesn't want them to take on other projects, right?

"Everyone is here, let's get straight to the point. Shen Hong, who presided over the meeting, said to Chen Mingshan next to him.

Chen Mingshan nodded, his face became serious, "In terms of die forging hydraulic presses, we now have a hydraulic press of more than 40,000 tons, but in terms of hydraulic presses, there is a big gap with the world, and this cannot be solved in a short time." Today, let's talk about the situation of the free forging press, many heavy parts are not suitable for die forging machine forging, and it is not cost-effective to make molds for one or two parts......"

Xie Kai frowned and looked at Wang Guilin and Zheng Yucheng, and saw that the two of them were also frowning, obviously unaware of it before.

That's not interesting.

You can't let them continue to invest money in free forging, can you?

"At present, the domestic free forging hydraulic press of more than 10,000 tons, a heavy and Shanghai heavy each have a 12,000 tons of free forging hydraulic press, are designed and built in China, due to the original domestic technical foundation and manufacturing conditions, now has begun to enter the late stage of life, the failure rate is getting higher and higher, seriously affecting the production ...... The double 10,000-ton free-forging hydraulic press, originally produced in the Czech Republic and sold to us by the USSR for some time, is now almost unusable, unless overhauled. Even if it is overhauled, not to mention the high cost, it is equivalent to remanufacturing, or even higher, and the technology is still backward......"

Zheng Yucheng wanted to answer, but was stopped by Wang Guilin.

Shen Hong looked at Xie Kai, Xie Kai pretended not to understand what he meant, and looked elsewhere.

It is clear that when 404 is wronged.

Zheng Yucheng, the funds of the 65,000-ton large press project, they all want to embezzle, and they are not ready to do it.

It's good now, the 45,000-ton press has just ended, so they not only have to continue to engage in 65,000 tons, but also engage in free forging, which is not a few million, tens of millions can be done.

Open forging is different from die forging, and the forging pressure provided is also different, the only thing that is the same is one word - expensive!

Chu Guorong and the others all looked at Zheng Yucheng and the others, and Xie Kai couldn't help but feel a little angry.

Whose idea was it?

No wonder Zheng Yucheng and Wang Guilin hid from Minister Shen Hong.

He immediately stood up, "Leaders, the 10,000-ton free forging hydraulic press is indeed very important, especially for the forging of heavy parts." We also support other units to engage in it, but our 404 is not ...... Ministry of Finance."

Zheng Yucheng and Wang Guilin are not easy to say, but Xie Kai is easy to say.

There are already many projects, and the financial pressure is getting bigger and bigger, so they are also stuffing projects into their hands.

"I just want to do it together...... Aren't you planning to build a large forging base in Jiayuguan? Just having a die forging machine won't work, isn't it ......," Chu Guorong smiled a little embarrassed.

"United, we pay for other units to contribute technology?" Xie Kai's words were not polite at all. "Mr. Chu, it's not like you don't know how many gold-swallowing projects we have!"

Zheng Yucheng said this to Long Yaohua and Li Mingshan.

This kind of thing, they don't actually help to block it.

Li Mingshan and Long Yaohua looked at each other helplessly, can Xie Kai's complaints be unclear to them?

"Die forging hydraulic press, we need, we do it ourselves! We have to continue to do 65,000 tons, that's what we need, we invest money, no opinion! But the hydraulic press and the free forging hydraulic press are all let us come, we 404 units, can't support it!" Xie Kai's words are hard to hear, "We are not a small treasury of the Ministry of Industry, what project we want, let us do what project." Even the military leadership did not say that we should pick up all the projects that all countries are not working on for the time being......"

Shen Hong looked at Xie Kai, and a wry smile appeared on the corner of his mouth.

He knew he would be taken for a bad person.

"Chief, if we have to accept these projects, we can only divert funds from other projects...... When we don't have enough funds to support it, 404 will be disbanded just like before......" Zheng Yucheng also stood up.

When it's time to say no, you have to say no.

This old guy is even more excessive than Xie Kai, and is completely threatening.

is not a threat to the Ministry of Industry, but a threat to Long Yaohua and Li Mingshan.

This kind of thing is really disturbing.

Up to now, the base has basically decided that it is not particularly necessary, and it is not possible to do projects as soon as it is necessary, and it is impossible for one unit to involve all areas of the national industrial system.
