"As for the small crucibles with pure molybdenum, you must wait until the large tungsten crucible is processed before high-temperature sintering is carried out in a vacuum furnace with a large tungsten crucible, so as to ensure that the performance of the entire pot meets our usage requirements..." Liu Yijiu sighed, these things are tied up one by one.

If it weren't for him, just the large tungsten crucible, it would have to wait until after the 21st century that the international community began to close a large number of tungsten and molybdenum products factories with heavy pollution, high energy consumption, reduced profit scale, and did not have much technical content to hand over the production orders to China, and even produce them in China. China also had such an opportunity.

Unlike other things, pure tungsten crucibles must be sintered for dozens of hours through high temperature and high pressure, and then they must be mechanically processed.

Technical difficulty is high. Pure tungsten products, especially huge crucibles, will have thin walls and very small force. If you are not careful, the entire crucible will break or crack. However, these large tungsten crucibles with hundreds of diameters are difficult to process because as the diameter increases, the length becomes longer, but the wall thickness does not change. If you are not careful, this thing will be completely abandoned.

Once there is fragmentation or material defects occur during sintering, the entire crucible will be scrapped.

A vacuum sintering furnace, high-frequency furnace three to five million, and this crucible alone will have to occupy one-third to half of the cost.

"Director Liu, this pot costs seven or eight hundred kilograms of tungsten powder, and the cost 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. With various costs, it would definitely not be cheap.

Hearing Chen Xiangwei's words, Zheng Hao, who was on the side, couldn't help but grin.

When it comes to money, he feels sore.

Liu Yijiu shook his head, thinking that this was not a problem at all. "We produce the raw materials ourselves, and from the foundation to the end. Even if it is scrapped, we will react these pure tungsten with chemical agents to make them remade. All we consume is labor and energy. Research and development of any product is necessary! What's more, the powder during rough processing of the blank after isostatic pressure can be used in carbide tools, and there is no need to go back and restore it..."

Liu Yijiu still knows this kind of thing very clearly.

In the end, the Republic's research on tungsten was basically the strongest in the world because this country has the richest reserves of tungsten resources in the world. After the 21st century, in order to seal off their domestic mineral resources, European and American countries began to import large quantities from China, although these high costs and profits were due to fiercely competitive products within China...

"Is these crucibles a waste of such high costs?" Zheng Hao hopes most that Liu Yijiu can cancel the investment in this area.

They really don't have much money.

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

The Republic wants to obtain a large amount of foreign exchange from the Americans, and relying solely on primary mineral resources, industrial raw materials, and even OEM costs, everything is too slow.

In order to allow the Republic to expand its foreign exchange sources in the early days, he had to be shown to Americans by these technologies and crafts that the United States did not produce in the late 1980s and early days. Of course, he had no choice.

If the leaders above were not allowed to understand the value of the rare earth industry and strategic resources that some other countries had not studied, the mineral resources of the Republic will still be dug by private individuals, and eventually the United States and Japan take advantage of the characteristics of Chinese people's preference for internal fighting and only exported to Japan and the United States at bargain prices.

Japan, a small country, desperately imported rare earth mines from China when they had the opportunity and then hoarded them.

Many electronic products, especially military electronic products, must use rare earth elements to improve performance. The precise guidance of missiles cannot leave some light rare earth elements.

The performance of cannon steel is improved, and the performance of new armor materials and even high-temperature alloys will be added to the added properties of different rare earth elements. The characteristics of this material have not been completely studied by the time of Liu Yijiu. However, some energy weapons must be based on some rare earth elements.

Unfortunately, at that time, the originally abundant rare earth resources on the land of the Republic had been hollowed out by the bastards in China who only care about immediate interests. In the end, they had to turn their attention to the sea...

"This thing is sold to Americans? Director Liu, isn't it possible? After all, the technology of the United States is much more advanced than ours..." Chen Xiangwei didn't think that their things could be exported to advanced countries like the United States.

Liu Yijiu didn't say anything, such a thing. Many people in China would not believe it. They did not pay attention to some treasures, but in the end they learned all the key things by Japan and Americans, but in the end they became something from others.

The equipment workshop is very busy, mainly to produce some tungsten and molybdenum materials, mainly various furnace bodies.

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

The various equipment modifications inside have been underway for a while.

"Xiao Liu, can these things really work? If Americans don't want these, we will be really stunned..." Zheng Hao and Liu Yijiu visited Factory 754. There was no need for them to interfere in various transformations. If they did everything themselves, don't expect to do something else.

After checking the renovation progress in the 754th Factory, the speed was still a little worse than they imagined. There was no way to do this. It was not comparable to the mountain here.

Factory 755 is one of the few electronics factories in Rongcheng. The scale of this factory is similar to Factory 754. The diodes produced are of no use to the current Jiuyuan base, but many electronic components can be produced here.

Especially some electronic products that need to be used on computer chips and radars.

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

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

She did not have the ambitions of other managers, but she just hoped that the factory would not go bankrupt and could pay wages to employees. The superior authorities asked for the transformation, so she naturally did it as required. Even if she didn't understand the things produced at all, it would not affect her serious execution of these tasks.

"Duan Huimin is good, and her execution ability is relatively strong." Zheng Hao saw the situation inside the 754 factory, which changed a lot from the decline they saw at the beginning.

The environment in the entire factory has changed a lot. When workers have nothing to do, they organize their studies in it instead of sitting together playing poker like before or having a group of children and employees sitting together while playing sweaters while chatting. There are no bare butts of unschooled children running around in the factory.

"It can only be used as a factory manager..." Liu Yijiu sighed.

If such a person is a factory director, if he does not have the leader of the Ninth Academy, and if he is not Liu Yijiu, he will eventually be facing the fate of bankruptcy.

"We don't let Americans know about these things from Factory 754? I think such products are what they need most, and they are also things that we can exchange for a large amount of foreign exchange at present. There is not much use in China, so we can provide them with crystals first..." Zheng Hao and Liu Yijiu checked various progress in Factory 755, and also listened to Duan Huimin's progress in promoting the factory's seven special technical agreements. These workers were idle for a long time, but now they have hope, so they naturally have to work hard.

People these days are relatively simple, and not many people hope to get a salary but not go to work.

"Doing raw materials production? We must not do such things!" Liu Yijiu firmly opposed, "If we want to export, we have to export finished products. After our chip development reaches a certain level, we will develop some chip exports specifically for the European and American civil markets, rather than just exporting materials such as crystals. Once electronic circuits are added on it, the price will be many times higher..." Liu Yijiu would not agree to these companies to supply various basic materials.

Unless high-temperature alloys, titanium alloys, and cemented carbides are super materials with insufficient domestic technology and insufficient production capacity.

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

There is only a little money in his pocket. Now, millions have disappeared without long.

"I have already made a fuss about this now, so I'll think about it again. If there is no problem, let's talk about it later. Don't worry, these factories will be more difficult in the early stages. As long as the products are right, in the end we will only think that our own production capacity is insufficient, and we won't think that these are burdens..." Liu Yijiu sighed.

Then I looked at the watch on my wrist and the Americans were about to arrive.

Several people left the factory and returned to the guesthouse. They were going to receive Americans tonight, and maybe they would restart negotiations tonight. (To be continued.)
