"As for the small crucible of pure molybdenum, we must wait until the processing of the large tungsten crucible is completed, and then it can be sintered at high temperature in the vacuum furnace with the large tungsten crucible, so as to ensure that the performance of the whole pot meets our use requirements......" Liu Yijiu sighed, these things are all linked one by one.

If there is no him, just the large tungsten crucible, we have to wait until the 21st century after the international began to close a large number of tungsten and molybdenum products factories with heavy pollution, high energy consumption, reduced profits, and little technical content, and handed over the production orders to China, and even produced in China, so that China would have such an opportunity.

Pure tungsten crucible is not like others, this thing must be sintered for dozens of hours at high temperature and high pressure, and then it has to be machined.

The technical difficulty is large, pure tungsten products, especially the huge crucible, will be because of the thin wall, the force can withstand very small, a little careless, the whole crucible will be broken or cracked. The processing difficulty of these large tungsten crucibles with a diameter of hundreds is even more because as the diameter increases, the length becomes longer, but the wall thickness does not change.

In the event of chipping, or material defects during sintering, the entire crucible is scrapped.

A vacuum sintering furnace, a high-frequency furnace of three to five million, just this crucible, has to occupy one-third to one-half of the cost.

"Director Liu, this pot will cost seven or eight hundred kilograms of tungsten powder, which is not low...... Chen Xiangwei didn't know their plan, but he knew how high the cost would be, a ton of pure tungsten powder would cost more than 200,000 yuan, plus various costs, it would definitely not be cheap.

Hearing Chen Xiangwei's words, the corners of Zheng Hao's mouth on the side couldn't help grinning.

When it comes to money, he hurts in the flesh.

Liu Yijiu shook his head, thinking that this was not a problem at all. "We produce our own raw materials and we start from the basics until the end. Even if it is scrapped, it is enough to react these pure tungsten into blue tungsten with chemical agents and re-prepare it, and we only consume various processing costs such as labor and energy. Research and development of any product. It's a must! What's more, the powder from the rough machining of the blank after isostatic pressing can be used in the carbide tool, and there is no need to go back to restore......"

For this kind of thing. Liu Yijiu still understands very clearly.

The research of tungsten in the Republic is basically the strongest in the world in the end, because this country has the world's richest reserves of tungsten resources, and after the 21st century, European and American countries have sealed their own domestic mineral resources. began to import a large number of these products from China, which were expensive but profitable because of China's fierce competition......

"Isn't it a bit of a waste that these crucibles cost so much?" What Zheng Hao hopes most is that Liu Yijiu can cancel the investment in this area.

They don't really have much money in their hands.

"What is waste? Do you think I'm really just because I'm upset that the Americans let them come to Rongcheng? Our new cannon steel requires heavy rare earths, and our guidance system needs light rare earths, which cannot be disconnected from pure molybdenum crucibles. The Americans and Soviets have not yet studied this aspect...... "Liu Yijiu's meaning is very obvious.

The Republic is too slow to obtain large amounts of foreign exchange from the Americans, relying only on primary mineral resources, industrial raw materials, products, and even the cost of processing.

In order for the Republic to expand its sources of foreign exchange in its early years, he had to be shown to the Americans by these techniques and processes that the United States had developed in the late eighties. Of course, he can't help it.

If you don't let the above leaders understand the value of strategic resources that the rare earth industry and some other countries have not studied. These mineral resources in the Republic will still be mined by private individuals, and eventually the United States and Japan will take advantage of the characteristics of Chinese people who like infighting to lower the price of each other, and only export them to Japan and the United States at the price of cabbage.

Japan, a small country, desperately imports rare earth minerals from China when it has the opportunity and then hoards them.

Many electronic products, especially military electronics, must use rare earth elements to improve performance. The precision guidance of the missile cannot be separated from some light rare earth elements.

The performance of cannon steel has been improved, new armor materials, and even superalloys have been added to these bases, and different rare earth elements have been added. The performance that is displayed becomes very different. The properties of this material have not been fully studied even in Liu Yijiu's time. Nothing more, some energy weapons. It must be based on some rare earth elements.

It's a pity that at that time, the originally rich rare earth resources on the land of the Republic have been hollowed out by those bastards who only care about their immediate interests in the country. Eventually, I had to set my sights on the sea......

"This thing is sold to the Americans? Director Liu, this is unlikely, right? After all, the technology of the United States is much more advanced than ours...... "Chen Xiangwei doesn't think that this kind of thing of theirs can be exported to an advanced country like the United States."

Liu Yijiu didn't say anything, this kind of thing. Many people in China don't believe it, they don't pay attention to some treasures, and as a result, the key things are learned by Japan and Americans, and in the end, they become someone else's things.

The equipment workshop is very busy, mainly for the production of some tungsten and molybdenum material equipment, mainly all kinds of furnace bodies.

As for the overall machinery and equipment used in rolling, they cannot be manufactured.

The transformation of various equipment inside has been carried out continuously for time.

"Xiao Liu, can these things really work? When the time comes, if the Americans don't want this, we will really be dumbfounded...... "Zheng Hao and Liu Yijiu walked around the 754 factory, there is no need for them to meddle in all kinds of transformations or anything, if they do everything themselves, don't expect to be able to do something else."

After looking at the progress of the transformation in the 754 factory, the speed is still a little worse than they imagined, and there is no way, this side is not as good as the mountain.

Factory 755, one of the few electronic factories in Rongcheng, the scale of this factory is about the same as that of Factory 754, and the diodes produced are not useful for the current base of the Ninth Academy, but a lot of electronic components can be produced here.

In particular, some electronic products that need to be used on computer chips and radars.

Some of the equipment in the base has been transported here by train, and it will be built into a silicon wafer production line. At the same time, the production of chips will also be put in this in the future, and now these factories, the largest investment is 754 factory and 755 factory, of course, there is also the state-owned Jialing Machinery Factory in Shancheng.

As for the future prospects of the factory, Duan Huimin, the director of Factory 755, is not sure about the future prospects of the factory, in the era of the few female cadres in this era.

She doesn't have the same ambitions as other managers, she just hopes that the factory will not close down and that the workers can afford to pay their wages or something. The higher-level authorities let the transformation, and she naturally did it as required. Even if she doesn't understand the things that are produced, it doesn't affect her from seriously carrying out these tasks.

"Duan Huimin is good, and her execution is relatively strong." Zheng Hao saw the situation inside the 754 factory, which was very different from the decay they saw when they came here at the beginning.

The environment in the whole factory has changed a lot, and when the workers have nothing to do, they organize and study inside, instead of sitting together and playing poker as before, or a group of children and workers sitting together and chatting while playing sweaters, and there are no bare-bottomed children who do not go to school all over the factory.

"I can only be a factory management ......," Liu Yijiu sighed.

Such a person, when he is the director of the factory, if there is no leader of the Ninth Academy, and the Ninth Academy does not have him Liu Yijiu, he can only face the fate of bankruptcy in the end.

"We don't let the Americans know about these things in the 754 factory? I think this kind of product is what they need the most, and it is also something that we can exchange for a lot of foreign exchange at the moment. There is not much use in China, we can provide them with wafer ...... first" Zheng Hao and Liu Yijiu checked various progress in the 755 factory, and also listened to Duan Huimin's progress in the promotion of the factory's seven technical agreements.

People in this year are relatively simple, and not many people want to just get paid and not go to work.

"Do raw material production? We must not do this kind of thing! Liu Yijiu resolutely objected, "If we want to export, we also have to export finished products, and when our chips are developed to a certain extent, we will develop some chips for export for the civilian market in Europe and the United States, rather than only exporting wafers." Once an electronic circuit is added to it, the price will be multiplied many times...... "Liu Yijiu will not agree with these companies to supply all kinds of basic materials."

Unless superalloys, titanium alloys, cemented carbides, these domestic technology is insufficient, the production capacity is insufficient super materials.

"But if we can't let the 755 factory have export products as soon as possible, what can we produce in China?" Zheng Hao said distressedly.

He only had a little money in his pocket, and it didn't take long for him to be gone

"I have an eyebrow for this now, I'll think about it again, and if there is no problem, let's talk about it then. Don't worry, these factories will be more difficult in the early stage, as long as the products are right, in the end we will only think that our own production capacity is insufficient, and we will not feel that these are burdens......" Liu Yijiu sighed.

Then I looked at the watch on my wrist, and the Americans were arriving.

Several people left the factory and returned to the guest house, where they were going to receive the Americans tonight, and perhaps negotiations would be reopened tonight. (To be continued.) )
