Super military empire

(I'm really sorry, the updates are a little bit small these days. Last night I was having fun with Tianhai Xiangyun, Huang Shiren, and Wu Anjun. Today Tianhai Xiangyun took me to his friend’s house for tea... There have been many things these days, update Less, I hope you understand, it will be fine after these few days!)

The trial production was successful. Taking into account the problem of mold change, this time 100 sets of main landing gear will be continuously produced, and only the main beam of the fighter that requires greater pressure will be replaced. Therefore, production is still continuing, and Liu Yijiu and others are unnecessary. Continue to stay here to watch the excitement.

Qi Hao once again raised the hope that the chief would give the calligraphy treasure, and Qi Hao directly wrote down Liu Yijiu's words and presented it to Er Zhong, but Liu Yijiu didn't care at all.

Liu Yijiu didn't intend to participate in the celebration banquet prepared by Duo. In the end, Qi Hao and others all spoke, and he could only stay here for a while.

"Director Jiang, the 70,000-ton large press project is now completed. I don’t know what your plans are for the next step?" Liu Yijiu sat next to Jiang Wen at the noon celebration banquet, while the other chiefs were pushing the cups for a change. , Asked Jiang Wen.

Jiang Wen was taken aback, and immediately looked at Zheng Hao, who was not far away, who was toasting with Qi Hao and others, and did not look at him at all.

For a while, Jiang Wen didn't know whether Liu Yijiu asked about their technical research projects or their plans for production layout.

I immediately didn’t bother to waste brain cells and asked Liu Yijiu directly, “Director Liu, we hope to expand our cooperation with the Ninth Institute in the next step...”

"Cooperation is okay, but only 70,000 tons of die forging machines are not enough at the moment. We have too many core parts of heavy equipment in China that need such equipment for forging." Liu Yijiu said lightly.

Jiang Wen didn't understand what he meant at all.

"We plan to build another 70,000-ton press!" Jiang Wen looked at Liu Yijiu's expression without any change, "or challenge to 80,000 tons."

"It is naturally no problem to manufacture another one. The 70,000-ton large die forging machine is enough for use at present, at least for the present 20 years. There are many businesses that need to use large forging presses in China. Two or three, there will be no business..." Liu Yijiu naturally has nothing to allow for the production of one or two more giants like this.

There are not too many large forging presses with more than 40,000 tons in the world. Many of them are concentrated in the hands of the Soviet Union and the United States. There are not many in Europe.

At the beginning of the Republic, there was only one 80,000 tons. Many production plans were even scheduled five years later. After they were manufactured, new models came out again, and the original design was wasted.

Eventually had to expand production.

The problem is that the Republic needs more than just a large die forging machine.

"I mean, I don't know if you are interested in free forging equipment." Fortunately, Liu Yijiu no longer sells them.

It is impossible for the Ninth Institute to devote energy to these basic equipment. Professional design requires the efforts of units in these professional fields.

Otherwise, the Ninth Institute will really become a monster at that time. Once the Ninth Institute has a problem, the entire national industrial system and technical system will have to be seriously affected.

"You mean a free forging hydraulic press of more than 10,000 tons?" Jiang Wen suddenly opened his eyes.

"Although die forging machines are very useful, they are only used for the manufacture of batches. At present, our largest domestic free forging hydraulic press is only 6,000 tons, which is not enough for many of our products. Therefore, We need more than 10,000 tons, even 20,000 tons of free forging!"

Liu Yijiu's face was a little complicated.

Free forging is different from die forging. Because die forging requires molds, and these molds are large, processing is difficult, and the manufacturing cost is high. Therefore, it is only suitable for mass production of structural parts.

Whether it is military products such as fighter planes or civilian products such as nuclear power, they can basically be regarded as relatively large batches.

However, for some single-piece and small-batch products, especially the models used for sample trial production, the shape of the part blank is manually controlled and operated, and can be deformed at will.It can eliminate defects such as shrinkage cavity, shrinkage porosity, and pores in the material, so that the blank has higher mechanical properties.At the same time, compared with casting, it has the advantages of lower cost and higher versatility.

Naturally, this is not without its shortcomings. The processing allowance of the blank is large, and the requirements for the operators are very high.

"Yizhong has Project 61111 over there, isn't it just getting a 12,000-ton free forging machine?" Johnson asked in surprise when he heard Liu Yijiu's words.

For these things, he spent a lot of time to make up lessons, so as not to be ridiculed by Liu Yijiu.

"Their 12,000 tons of free forging have just started, right? And they don't have enough funds, nor have they mobilized the nation's power like we do for die forging, Director Jiang, how long do you think they can do it?" Liu Yijiu Asked Johnson very calmly.

In China, there is not much experience in large forging machines.

And directly doubled.

Those who don't understand the hydraulic free forging of tens of thousands of tons, and the die forging machine of tens of thousands of tons, all think that the most complicated is the forging of tens of thousands of tons.

In fact, I don't know that the free forging machine of 10,000 tons is more complicated than this tens of tons.

At present, only the Soviet Union and the United States can have the design and production capacity of free forging machinery of more than ten thousand tons in the world. Western countries still originate from the United States, but they have just exceeded ten thousand tons.

To engage in nuclear submarines, warships, and even large military transport aircraft, there are higher requirements for free forging equipment of more than 10,000 tons, especially for nuclear power and large parts of steam turbines.

"Don't you go to exchange feelings with other personnel, what are you talking about hiding here?" At this moment, it happened that Qi Hao also came over.

"Talking about the free forging machine! Xiao Liu wants a large free forging machine of 20,000 tons..." Johnson directly put forward Liu Yijiu's highest request.

Qi Hao was taken aback, "We haven't even made a breakthrough in free forging of 10,000 tons!"

Not to mention 10,000 tons, there is no breakthrough for 8,000 tons.

"Before this, didn't we even have 40,000 tons of die forging machine technology?" Liu Yijiu still said calmly, "Our domestic technical force is actually better than we thought, but the scale is not as good as the Soviet Union and United States. The only problem is that we have not pooled these technical capabilities..."

Qi Hao was taken aback, thinking about it, and felt that Liu Yijiu's words made sense.

This has also aroused their interest. It is a great good thing for the entire Chinese military industry and even the Chinese industry to continue to make breakthroughs while taking advantage of this.

The few people did not continue to waste time at the celebration banquet, but went to the second floor meeting room.

Jiang Wen also called the relevant technical personnel to the technical conference room. According to this rhythm, they will continue to tackle key problems in the project.

If it succeeds, then the entire Erzhong will be China's first heavy machinery and equipment design and manufacturing unit.

"There is no need to explain the purpose and performance of free forging. You who specialize in forging equipment and forgings understand better than anyone else. You also know that some large and heavy parts and small free forging machines are not enough. I will ask everyone In a word, do you have the courage to challenge the 15,000-ton, 20,000-ton free forging directly from the 6,000-ton technology? That is the next step. At present, the largest free forging in the world is the 14,000-ton free forging in the Soviet Union. , There may be 15,000 tons soon..." After Liu Yijiu entered the meeting room, he directly asked Erzhong's technicians.

In the second aspect, the managers are very interested in this, but their technical staff frowned.

Even Chu Guorong, Cheng Xiaoci and others have very heavy faces.

"Director Liu, I think that as long as there are enough funds, this is not a problem!" Jiang Wen would not refuse such a large-scale project, especially one that does not exist in China.

The political achievements are in front of them.

And there is no need to go to the central government to run the project. The Ninth Institute has sufficient funds and can use their relationship to use the national technical force to research key problems for the dual. Who would have an opinion on such a good thing?

"Director Liu, this technical difficulty is really too great. Our experience in this area is not very sufficient, and the domestic technical reserves in only forging are also insufficient. We can produce 70,000 tons of die forging machines, which is similar to our previous The design plan has concentrated the nation’s top technical forces for nearly ten years of design demonstrations. But free forging, even if we are duo, we are currently only challenging the 8,000-ton design capacity, which is why the first side has been unable to The reason for the breakthrough and the slow progress..." Chu Guorong ignored Jiang Wen and kept indicating to himself.

The technical difficulty is too great.

Even with sufficient funding, Liu Yijiu's request is very difficult.The technical project of the Ninth Institute is very tight for time. Even the 70,000-ton die forging machine, they worked day and night to get it out in such a short time.

Otherwise, he would not refuse such a project.

"We need to have a large free forging machine with a capacity of more than 10,000 tons and a die forging machine with a capacity of tens of thousands of tons to form a closed large-scale forging industry chain! This is the requirement of the aviation industry and the production requirement of some of our heavy-duty machine tools. The above free forging equipment cannot provide such processing services, and even our aviation industry chain cannot be perfected!" Liu Yijiu ignored Jiang Wen, who looked forward to his face, and Qi Hao, who looked at him with some doubts. People, but looking at those technicians who dare not look at themselves, said seriously."I know that this technology is very difficult and it is a huge challenge for us! We have not been in touch with the 61111 project, but their design ideas have gone wrong from the beginning, whether it is air hammer or steam-air It is very difficult for the hammer to reach 10,000 tons, and it is fast forging!"

"Director Liu, do you mean that we don't choose the forging hammer method?" Cheng Xiaoci didn't understand.

Isn't it all in this way?

"The technical difficulty is too great, we directly adopt the hydraulic mode. With 70,000 tons of die forging design experience, using hydraulics to solve the pressure supply problem is not too big a problem, right?" Liu Yijiu nodded.

This is also a matter of no way, we can only solve the problem first at present.

"Do you have to do this project again?" Qi Hao felt that he was here to serve as a foil.

"If Erzhong is willing, the project will start today. If not, we will look for interested and confident units to engage in this project." Liu Yijiu nodded.

Must have.

"Director Liu, if we are interested, how could we not be interested! We are not only interested, but also confident!" Jiang Wen immediately became anxious. The research funding of the Ninth Academy is much easier to get than the state's financial allocation, and project approval It's not that long, and immediately turned to the two engineers who were struggling and asked, "Zhou Zong, Cheng Zong, are you right?"

Chu Guorong was not as eager as Jiang Wen. He communicated with Cheng Xiaoci in a low voice, and then asked the other technicians next to them, before turning to Liu Yijiu and asking, "Director Liu, how much time do we have to complete this project? ?"

The Ninth Academy's money is not so easy to take.

Although the approval of national projects is complicated, it does not urge the Ninth Institute to urge them to produce results, so that all the technicians do not even have a rest.

Just like today, it was originally the Gregorian New Year, New Year's Day, everyone should rest...

After successful trial production of 70,000 tons of large press, it should be stopped for maintenance, but it was put into production after the trial production was successful today. After the production is completed, the trial production is completed after 100 sets of landing gears...

Time is the most lacking.

"Two years!" Liu Yijiu stretched out two fingers."According to the domestic technical capabilities and your accumulated experience, it is enough. At the end of 1988, I will see 15,000 tons of free forging machines for trial production!"

"It's impossible!"

Cheng Xiaoci immediately shook his head.

Liu Yijiu was thinking too well.

Design from the beginning, then have to demonstrate the design plan, and have to carry out production. From start to finish, it only takes two years. No one can bear such pressure.

Even 24 hours a day, it cannot be manufactured.

Liu Yijiu did not speak, but looked at Chu Guorong.

Chu Guorong was obviously shocked by the short time Liu Yijiu gave.

Many large parts have a manufacturing cycle of several months. If the current time given by Liu Yijiu is used, the time they spend on design and demonstration is only one and a half years.

He kept weighing time in his mind, wondering why Liu Yijiu was so eager.

When Jiang Wen heard this time, he didn't dare to agree at will.

Everyone is staring at Chu Guorong, his decision will determine whether this project is going on in the second.

In the end, Chu Guorong nodded, but made a request to Liu Yijiu, "Director Liu, we cannot guarantee this. We can only give it a try and try our best to complete this project. But we need to start the project. Have sufficient capital guarantee, and this may cause a huge waste of funds..."

"Funding is not a problem. The Ninth Academy will first allocate 100 million yuan of special funds to you when the project is launched!" Liu Yijiu said proudly.

The problem that money can solve is not a problem.

Now they are not short of money, but time!
