Super military empire

"Xiao Liu, with their equipment, can they make the high-precision sights we need? Isn't that a joke? Why don't I feel unreliable!" The 298 factory arranged for Chen Dashan and his group to visit them the next day. Factory.

This year, this is basically the standard model.

Xiao Siwei, the director of the External Liaison Office, and Xue Dingshan, the technical person in charge of this research, accompanied several people to visit their optical instrument production line, mainly to make Chen Dashan have sufficient confidence in them.

"Leader Chen, although the equipment here is old, there is absolutely no problem in production. The production process of optical lenses is the same, the only difference is the mastery of some time in the production process and the ratio of various formulas. Don't look at these equipment. Many of them were produced before the founding of the People’s Republic of China, and a large part of it was aided by the former Soviet Union. They have been around for decades, and their appearance is not very good. Many of them have a much lower failure rate than our domestic equipment..." For these obsolete and old equipment, Xue Dingshan and others cannot say that they are much better than domestic equipment.

Can only say that the failure rate is small.

The technology for producing optical glass in China is already very backward. Even if the Soviet Union assisted the new China in the past, it was because the Soviet Union did not learn it thoroughly. If it retains some of the new China, China's technology in this area can be imagined. Up.

Optical glass generally uses furnace to make billets, melt raw materials, cool to form the billet, cut the billet and chamfer the billet. According to the drawings, the cut pieces are heated and softened and then pressed into a compact shape, annealed to relieve stress, and the detection performance is in line with the use. Before entering the grinding process of optical glass manufacturing.

It seems that the process is very simple, but this simple process requires a lot of technology.

"Mr. Xue, what is the qualification rate of our materials?" Liu Yijiu saw that the clay furnaces were all used here, but did not see that the cost is high, but the solution can be kept stable, and there is little bubbles and stirring in the raw materials. After that, these defects were left like water veins.

What's more, the platinum furnace has always been recyclable. I don't want the clay furnace to be used once.

To produce high-performance optical glass, a platinum furnace must be used.

What's more, the price of platinum in this era is far behind that of gold.Gold is gold, platinum is not gold, it is the opinion of most people in this world.

After all, platinum is just a raw material used in industry.

Upon hearing Liu Yijiu's question about the most critical optical glass production pass rate, even Xue Dingshan, who is engaged in technology, smiled bitterly.

"In these years, after continuous improvement of production technology, adjustment of temperature and various technical parameters, we have increased the pass rate from 10% to 15% to 20% to 25%... …" They are still not satisfied with such production efficiency.

After all, whether these optical glasses can be used or not will be known after processing later.

"Why not use a platinum furnace? Although the cost of this furnace is many times higher than that of a clay furnace, it can be recycled, and the quality of the solution with rare elements added to it can be guaranteed during the melting process. At the same time, it is also better than clay during cooling. The effect of the furnace is better..." For optical glass, Liu Yijiu knew that.

"Comrade Xiao Liu, is there any theoretical basis for this? Or do you know who uses such a production process?" Xiao Siwei was upset when he heard Liu Yijiu's words.

You said that you are a young man, and knowing a little about gun design is enough. So young, why do you have to put green onions in your nostrils and run here to pretend to be an elephant?What's more, in the whole of China, their 298 factory has the best optical glass production technology. At the same time, the person with the best technology is Schrodinger in front of them.

They have been groping for so many years and there is no way to improve. Could this young man who doesn't know what optical instrument is better than them?This makes them such old guys who have been in the technology for a lifetime to feel so embarrassed!

"Director Xiao, I really don’t have any theoretical basis for this. As for whether anyone uses this kind of production process, I don’t know about it. If I didn’t see it with my own eyes, I can’t guarantee it. However, I was studying When designing firearms, I have heard from our teacher that the top foreign optical glass is manufactured using a small platinum furnace, so that stable optical glass can be obtained..." Liu Yijiu had to push this to He doesn't know whose teacher it is!

It is absolutely true that the platinum furnace makes optical glass.

"Can the pass rate be increased to 40%?" Xue Dingshan on one side couldn't help his eyes shining upon hearing Liu Yijiu's words.

"The specific situation is not clear, but it should be able to exceed 50%. It was one of our professors who mentioned it at the beginning, and I forgot..." Liu Yijiu knew what they were going to ask next and directly blocked them with words. Living.

"So high!" Xue Dingshan was shocked.

"How is it possible!" Xiao Siwei also felt incredible.

It is impossible for foreign countries to have such a high yield!Optical glass is not ordinary glass. In the melting process, in order to disperse the bubbles, it needs to be stirred. The bubbles have no dispersal defect. The veins produced by stirring are also defective.

As long as there are defects, it will affect the use effect.

It has always been because these defects cannot be resolved, so the output is low, even in the middle of the 21st century, there is no way to eliminate defects such as bubbles and veins.The yield rate is only 50%-70%!By the end of the 21st century, this problem was solved. Unfortunately, Liu Yijiu was not a professional technician in this area.

He can't help it.

"Whether it is possible to achieve such a good product rate, it is completely possible to experiment. Only the results obtained through experiments are the most reliable." Technical matters do not have Chen Dashan's say.Liu Yijiu couldn't guarantee these things.

But he is absolutely certain that the quality of optical glass made in a small platinum furnace will be more stable than that made in a clay furnace, and the yield rate will be much higher.

"..." The two didn't say anything, but they had decided in their hearts that they would definitely have to try.

With an idea in mind, I took Liu Yijiu, Chen Dashan and others to visit the next processing workshop. The production process of precision parts processing, surface treatment and assembly workshops did not have that detailed introduction.

"Director Cao, there must be a coating on the scope and objective lens we require, that is, the situation outside the 62-type telescope. After all, the sniper rifle needs to be used all-weather. Especially when performing some tasks, sniper The hand is likely to be lurking somewhere for several days..." When leaving, Liu Yijiu emphasized this issue to Cao Jingui again, "Also, in terms of quality, I hope you can make all products meet our requirements. ..."

The seven-nine style of the year was due to the quality of the scope, which caused the first new Chinese sniper rifle to have many headaches, and basically did not establish much merit on the battlefield.Eventually it was quickly replaced by Type 85.

"Comrade Xiao Liu, don't worry, we will definitely work hard to provide products that meet your needs!" Cao Jingui said to Liu Yijiu with a smile on his face.

A few can guarantee it, but if there are more, they can't help it.

Once the superior comes to the production task, it is often necessary to hand over a sufficient quantity of products within the specified time!

"Master, can their production environment and equipment provide a scope that meets our requirements?" For the other party's production environment and conditions that are far from being compared with the base, even people like Qin Huaibao who don't know much technology, Are very skeptical.

"If they can't produce it, it is estimated that domestic production can't be produced." Liu Yijiu sighed helplessly.

There are more than ten domestic optical instrument manufacturers, all of which were established by the 298 factory with technical support.The best technology is still in the 298 factory.

"Xiao Liu, should we leave someone here to stare at them?" Chen Dashan whispered to Liu Yijiu when he was about to arrive at the train station, "This way, once they are done, it's totally fine. Bring back the scope used for the sample in the shortest time?"

Chen Dashan is worried that he will not hurry up here.

"That's not so good? After all, Qin Huaibao doesn't know much about this..." Liu Yijiu couldn't help but hesitate while looking at Qin Huaibao who was secretly looking at Wang Xinyue from time to time.

He worried that Qin Huaibao would leak some secrets of their base in front of the beauty.A man, in order to gain a good impression from a woman, he will definitely show how he is different from the men around him.What Qin Huaibao can attract the girls in front of him is the big guys hiding in their base.

Dongfeng 5, a missile that can hit 8,000 kilometers away, can destroy an atomic bomb in a big city in the United States. You never have to worry about energy exhaustion, and a nuclear power plant with insufficient power... These things lack understanding of the entire world. Girls are absolutely powerful!

Qin Huaibao originally liked Wu Yue, a little nurse with big braids, but how could Wu Yue, who always wears a light blue nurse uniform, be compared with Wang Xinyue who is wearing a trendy dress!

Even if Wu Yue's face is much better than Wang Xinyue's.

"It will be much more convenient to leave a representative in the factory. I hope to be able to manufacture the products we need in the shortest possible time. After all, they don't need to design these sights..." Wang Dashan is now eager to see With a scope, a sniper rifle that could easily kill a thousand meters away appeared in his hand.

"Let's do it! Ask Qin Huaibao first." Liu Yijiu nodded.

Qin Huaibao was absolutely willing to become the representative of their base in the 298 factory.Liu Yijiu explained some things he needed to pay attention to, and after asking him to recite the confidentiality regulations, he boarded the train back to Rongcheng under the urging of Chen Dashan.
