Zheng Yucheng's words made Xie Kai and Chu Guorong shut up.

The determination has already been made clear in the words.

"Director Zheng, this matter is not a matter of anger, it can be done with will. We have to consider our financial affordability, the level of domestic technology, and our needs. After a while, Xie Kaicai said, "65,000 tons compared with the 30,000 tons already in China, it seems that the forging capacity has only doubled, and the technical difficulty must be at least ten times higher." ”

Xie Kaibi knows that the technical difficulty of the big press is not as simple as one plus one equals two.

In the field of industrial manufacturing, the development of any technology, to a certain extent, even if it is only a little bit of improvement, the required technology is geometrically multiplied.

"Comrade Xie Kai is a person who understands!" Chu Guorong sighed in his heart when he heard Xie Kai's words.

Originally, when they heard Zheng Yucheng boast about this young man, they were still a little unimpressed, and began to show friendliness, just out of politeness to the gold owner.

Zheng Yucheng doesn't know much about these, his head is hot, and he wants to make the world's largest and most advanced die forging machine, which is a good idea.

Everybody in the industry has this idea.

The problem is that you have to be down-to-earth and based on reality, otherwise you won't be able to do it at all.

"The big press is a reflection of the country's industrial manufacturing strength. We all know what the level of our domestic industrial base is, although no one wants to admit that it is worse than others, but the gap with foreign countries has to be faced. Just catch up. One step at a time is more down-to-earth!" Chu Guorong said to Zheng Yucheng.

Zheng Yucheng was in a bad mood by him and Xie Kai, and he kept changing cars and planes all the way, so he simply closed his eyes and recuperated.

The distance from Rongcheng to Erzhong is not far, but because the roads here are not as dense as the highways in later generations, and the freight transportation in the southwest is mainly automobile transportation, it took more than two hours to reach Erzhong.

By the time I arrived, it was already dark outside.

Shen Hong and others were waiting for Zheng Yucheng's arrival, Zheng Yucheng and Xie Kai didn't rest, they couldn't take care of eating, so they sat in the conference room with them.

After some greetings, Zheng Yucheng took the lead in saying: "From the beginning, we understood very clearly, taking over the 65,000-ton large press project that the country has launched because of many aircraft and missile projects, so if we propose to engage in 30,000 tons or 45,000 tons first, we won't talk about it." We don't pay for it!"

Even if Shen Hong was present, Zheng Yu would not give the slightest face.

Xie Kai was also helpless.

In this conference room, all the top technical experts in China, especially Shen Hong, who is not tall, wearing a black Mao suit, wearing a military coat outside, bald, but in good spirits.

Xie Kai admired these legendary bulls.

While he was looking, Shen Hong, known as the father of industry in the border area, was also looking at him.

Before coming, Zheng Yucheng boasted about how Xie Kai defended the sky, which aroused the interest of these big bulls, especially Shen Hong, who was looking forward to seeing such a young man.

No one expected that Zheng Yucheng would show your attitude as soon as he came up.

Only 65,000 tons of die forging machines were invested, and no money was given for the rest.

"Comrade Yucheng, I explained to you before that 65,000 tons is already the ultimate manufacturing capacity in China, and we have taken such a big step directly from 30,000 tons, and there are too many problems in the middle. Shen Hong looked at Zheng Yucheng and said, "Designing and manufacturing a 30,000 or 45,000 ton first will reduce the difficulties a lot." ”

"Where's the time?" asked Zheng Yucheng.

Even Shen Hong had nothing to say.

The question of time is something they can't face.

"Our Yunshi can't wait that long, and the 45,000-ton press is just barely enough for Yunshi. What if we want to develop a larger aircraft? When the time comes, we will build 65,000 tons? We don't have so much time to wait, and we don't have such a huge amount of money to support! We will also find it difficult for the state to support a project that the state cannot support!" Zheng Yucheng asked for a 65,000-ton press to be launched directly, with his own full considerations.

Xie Kai also understood Zheng Yucheng's thoughts.

Yunten to now, there is still a prototype is being assembled, the prototype of the previous test flight, the frequency of take-off has become lower and lower, every time the test flight, it has to go through a comprehensive inspection.

Even if the parts are replaced, it doesn't make much difference.

The various data obtained from the test flight were used in the new modification design scheme, and the new large aircraft could not be tested if the large press was not made.

"Without a large press, we can only use the old method of Yunshi manufacturing, forging small parts, and then welding. Now that the plane is becoming more and more dangerous, Ma Fengshan and Cheng are here from time to time, and there is no need to hide anything at this time......" Zheng Yucheng directly threw the topic in front of Ma Fengshan and Cheng from time to time.

The welded structural parts cannot compare the strength with the overall forged structure.

They can't even argue how long the overall structural strength will be when the aircraft is safe and useful for its theoretical design.

Everyone looked serious.

The large press was originally used for key aerospace components.

Aviation products have much higher requirements for manufacturing strength than aerospace missiles and rockets.

"In that case, let's go according to the original project?" Shen Hong asked everyone.

Chu Guorong knew Zheng Yucheng's thoughts on the way back.

"We're fine. Chen Mingshan, deputy director of the Department of Mechanical Engineering at Huaqing University, said, "The previous design only needed some modifications. ”

Huaqing University's design ability is definitely the top in China in terms of heavy industrial equipment?

"Isn't the prototype also produced?" asked Zheng Yucheng.

"It's really produced, and some of the designs need to be modified. Chu Guorong smiled bitterly, it seems that Zheng Yucheng has done a lot of work here.

It's so important to know the whole project.

"Now that the design work has been completed and the prototype has been manufactured, does Director Chen need more time for the design modification work?" Zheng Yucheng almost didn't give Shen Hong a chance to speak at this time.

It's as if he's the one who presides over the job.

"Their design revision work has never stopped!" Shen Hong said with a smile, "as long as it is determined that it will be carried out and the funds are sufficient, the heads of relevant units across the country can be summoned to divide the tasks......

Xie Kai was a little dumbfounded.

It was said that the design work would take a long time.

There are complete blueprints, which he believes.

The research field of the Department of Mechanical Engineering of Huaqing University is mainly in this aspect, after undertaking the design work of 80,000 tons and 100,000 tons of large presses in China, the design drawings were taken out within a few years, and even said to the outside world that the design work of 160,000 tons of large presses has been completed.

At that time, there was no need for such a large forging equipment in China, and once the country needed it, it only needed to be manufactured according to the drawings.

"It's true, if production starts now, some of the technology of the big press can only reach the level of the sixties abroad......" Chen Mingshan did not hide it.

The 65,000-ton large press project was proposed in the seventies for large aircraft, J-9 fighters and some key rocket models.

"Is it enough?" Zheng Yucheng asked Ma Fengshan from time to time with Cheng.

The two of them nodded hurriedly, "It's completely enough." ”

45,000 tons of 10 tons is enough, and there are 6.5 tons, naturally there is no problem.

"Minister Shen, I have to trouble you about this. Zheng Yucheng said to Shen Hong with a smile, and then stopped talking.

Something that originally needed to be discussed for a lot of time was brought to the point where construction was about to start with a few words from Zheng Yucheng, and everyone had different expressions on their faces.

Xie Kai was even more foggy on the side, he did not know much about the current situation of large presses in China, and he did not read the information carefully about the dismounted projects that the base had obtained.

When Zheng Yucheng discussed with Wang Guilin and others before, he didn't say that he could start construction directly, and on the way here, Chu Guorong also said that he was studying whether to build 30,000 tons or 45,000 tons first.

"What trouble am I? This is the most important weapon of the country!" Shen Hong said with a smile, "Don't worry, no matter how busy I am, I have to help you get this thing out first." There has been no more technical conference war in China for many years. ”

"I'm sure I'm relieved that you're in charge of the work. Zheng Yucheng said with a smile.

"Okay, let's wait here for two more days, we will ask the technical person in charge of the relevant supporting unit to come over in the next two days, and just throw off our arms and start working!" Shen Hong's words confirmed that the construction was about to start.

Xie Kai couldn't help but be anxious.

But there is no place for him to speak.

The meeting didn't last long, and there was no dinner, so in the evening, the group ate and drank in the cafeteria of the Erzhong Guest House, while continuing to discuss the project, Xie Kai listened all the time.

"Lao Zheng, this is the whole thing, where do we get so much money?" Xie Kai and Zheng Yucheng shared a room, and after they went back, they couldn't wait to ask the doubts in their hearts, "Didn't you originally say that there were a lot of problems?

This is what Xie Kai can't understand the most.

"Otherwise, what do you think I'm bringing you here for? There's no problem with Huaqing University, they're only responsible for design, but on the second side, the conscience will be greatly damaged...... They hope to use our funds to build a 30,000 or even 45,000 ton press in the name of producing a testing machine!" Zheng Yucheng explained to Xie Kai with a smile.

"They said that it would be less technically difficult to build it first. Xie Kai was puzzled.

"Build first, we don't need enough, do we have to continue building?" Zheng Yucheng asked Xie Kai.

Xie Kai nodded, "There are more than ten units in the Soviet Union, and one or two more in our country is also a good thing, especially many 45,000 tons can be forged and formed, and there is no need to occupy the production capacity of 65,000 tons of large presses." ”

"yes, so, we do 6.5, and Duo does 4.5 themselves, but they don't have the money. Zheng Yucheng smiled, and his mouth full of white teeth was revealed.

Xie Kai understood a little, but Shen Hong's attitude made him a little confused, and he was clearly on Zheng Yucheng's side, "Why does Minister Shen want to help us speak? Isn't it more in line with his wishes if there are more domestic equipment and stronger manufacturing capacity?"
