Chapter 806

For the 80000 ton forging press project, Yunfei can't afford not to be excited.

For heavy industry groups like him, the research of many large-scale projects can only make the performance of some key parts meet the design requirements and prolong the service life of the equipment through such a large forging press.

For example, the spindle and column of the turn milling compound machining center supporting the Three Gorges project, which can bear hundreds of tons, need such large equipment for forging, otherwise the service life will be very short. There is only one 40000 ton hydraulic press in the shipyard of Shanghai stock market, which was only developed with the help of Soviet experts in the 1960s.

With 40000 tons of equipment, the pressure is no big problem for the forging of some conventional heavy parts, but it is a little weak for the precise shape forging of some super heavy large parts.

Often a blank has to be heated repeatedly and then forged to barely achieve the design effect.

This is also a problem that China's large warship and large aircraft projects have been unable to make breakthrough progress.

This is not something China doesn't want to do.

But this year, all large state-owned factories are in recession, and everyone wants to settle the project in their own factories. This makes it impossible for China to launch a project as in the early days of the founding of the people's Republic of China, so that the whole country can concentrate on tackling key problems in large projects.

Now it involves interests and the survival of each factory. Under such circumstances, no one is willing to let others obtain such a large project.

Take the 60000 ton press obtained by Yunfei's original world Erzhong as an example. At that time, Erzhong was basically on the verge of bankruptcy. They supported it by making automobile die forgings. For such a large factory, the annual gross profit was only 300 or 200 million, and only they knew how little the net profit was. However, after the 60000 ton press was developed, dozens of aerospace supporting plants appeared overnight in the area around Erzhong!

The radiation range of a large press is very wide.

There are no more than ten large presses with more than 40000 tons in the world. Before China launched the large press, the highest record holder of the world's highest pressure machinery was the 75000 ton press of the former Soviet Union. The United States, the world's largest scientific and technological power, has no way to surpass the former Soviet Union in this regard. Many people even wonder if the former Soviet Union had not disintegrated because of economic problems, it would have begun to build bases on the moon by the 1920s.

Scientists in this country are crazy!

If China produces a large press of 80000 tons and then tackles 100000 tons or 120000 tons, it is of great significance for China to change from a manufacturing power to a manufacturing power.

This is also the reason why the country had to bite its teeth in the end.

Forging presses of 80000 tons and 100000 tons play an irreplaceable role in the structural parts of a new generation of fighters and space shuttles. Especially when the material technology is not qualified.

Take the most obvious example. In ancient times, iron could be forged into steel by repeated forging! In this way, we can see the influence of pressure machinery on the machinery industry.

Even in countries where the United States can produce the most advanced materials in the world, most of the parts on the aircraft also need to be forged and then precision machined. However, their material technology is advanced, and their requirements for pressure machinery are far lower than those of countries with hard injuries in materials such as China.

"You boy, it's hard to find you one day!" The day after Yunfei returned to Chengdu, Huang qiaosong took a fat middle-aged man to the Jiuyi group. The old boy has been waiting for himself.

"Lao Huang, let's get down to business when we have something to do. I didn't sleep all night last night..." the tired cloud Fei yawned.

The bear child just born has to eat in a moment. As a father, Yunfei feels that the child should accompany him on the first night of coming to the world. How do you know that it will be forced all of a sudden? The bear child didn't eat much at one time. He was hungry again every few minutes, or he pulled as soon as he was full. He didn't know how many times he woke up in a night. In order to tell others that he was unhappy, he was bitter

Yunfei, who was already a little nervous, didn't sleep a whole night.

Slap big children, the body is soft, Yunfei, there is no way to hold hands at all. Moreover, the bear child just born doesn't have much power to suck out the breast milk, and often cries with hunger... There are many daughters in the Mao family, even Mao Yixin and Mao Yaqiu are in the ward. Every time the bear child pulls a diaper or wants to eat when he is hungry, he has to toss for a while, Yun Fei, who accompanied him in the ward, could only hold his eyes and watch a large number of sisters-in-law busy under the command of Qing yu'e.

At this time, he fully realized how difficult it is for a woman to bring up a child.

He even wondered who was busy for ye Beichun when she had a child. Ye Wuqiu was at school at that time. The old lady was in poor health alone. How on earth did this woman persist?

Therefore, Yun Fei found that he owed ye Beichun more.

One night, I couldn't sleep. I just slept for a while the next day, but I was woken up by Deng Lanqing's phone. Geely is already pushing the progress of their robot project!

Before he arrived at the Research Institute, Jiang Jianxing called again and Huang qiaosong arrived. You know, last time he just appeared in the company, Huang qiaosong, an old guy, came to the 91 group by helicopter.

"Are you excited or tangled? Should I congratulate you first and then prepare a big red envelope? " Huang qiaosong is also quite clear about Yun Fei's family.

"Come on, if there's nothing serious, I'll go to bed. I've been hurt by you, an old man. Now I'm considering whether to let someone block you, an old man, from entering the door... "Yun Fei said with a bitter smile.

"This is Xiaoci, the second deputy chief engineer of, and this is engineer Chu Guorong..." at this moment, Huang qiaosong introduced the two people around him to Yun Fei“ Yun Fei, did Xiao Jiang tell you what we came for? "

Yun Fei nodded, greeted Cheng Xiaoci and Chu Guorong, and then said, "Lao Huang, it's not easy to do this. Money is a small problem, and the key technology is the biggest problem... "

Due to the lack of technical data and the detailed information of various countries in this regard, China has not even developed a 60000 ton press and directly launched an 80000 ton press, which will definitely require more R & D funds.

The country does not set up a project for this, at least not at present, which can not be said to be without reason.

"Mr. Yun, technology is not difficult. When the former Soviet Union disintegrated, we got the technical data of 68000 tons of press from them. Although our Erzhong has been in recession these years, our design institute has never stopped digesting and absorbing this technology..." Cheng Xiaoci saw that Yun Fei was a little reluctant and was in a hurry.

If this project wants to be approved by the state, it must be approved by dozens of departments. This is a very troublesome thing, and it may even have to run for several years. It's much easier to get the support of Yunfei, China's youngest rich.

As long as he agrees, there will be no problem with capital, but there will be no problem with technology. Is that still a problem? Even if the project is approved by the state, the technical problems have to be solved by themselves, don't they? Jiuyi group has No. 1 forging press factory in Northeast China, and has a very good relationship with northern heavy industry group.

If Yun Fei nods, North heavy industry group will not hinder in this regard, but will provide greater technical support.

Northeast forging press No. 1 factory used the forging press technology and engineering technicians in hand to exchange the stamping machine business of North heavy industry, which makes the technical heritage of North heavy industry begin to become profound. They are the biggest competitors of Erzhong. If they can participate in the direct one-time production of two sets, then one south and one north will radiate all over China and even the world, and China's whole industrial situation will change.

"Did you get technology from the former Soviet Union?" Yun Fei said in surprise. After the disintegration of the former Soviet Union, many experts were taken away by the United States, but the technology was cheaper than China. This is an indisputable fact.

The Soviet expert building of Chengdu 132 factory is still heavily guarded!

No wonder it was as easy as drinking cold water when he built a 60000 ton press in the world. It turned out that the technology of the former Soviet Union was in hand. As long as we have basic technology and design upgrading technology after digestion and absorption, it is definitely not difficult to build a strong country like China.

This is also the reason why European and American countries have been blocking China technically.

Once China gets the basic technology, the whole world can no longer stop the pace of China's rise

"Cloud boy, if you want to do research on heavy machine tools, don't you also need such large pressure machinery? Isn't the impeller factory in Guocheng unable to produce these businesses? This is the most critical supporting project of our No. 20 project... "Huang qiaosong patted Cheng Xiaoci on his chest and they promised to persuade Yun Fei to give money.

At the moment, Yun Fei has a sign that he wants to kick his son. He won't let it happen anyway.

Instead of letting Yunfei put his money into his robot project, it's better to let him make some contributions to the development of heavy industry in China!

"It doesn't matter whether we have this thing or not. A 40000 ton press is completely enough for our research. Lao Huang, it's not enough for you to take money out of my pocket. You also helped Erzhong take money out of my pocket... "Yun Fei said very speechlessly.

Huang qiaosong is so shameless.
