"Xiao Liu, just these equipment can make the high-precision scope we need? This is not a joke, right? Why don't I feel it's unreliable!" The next day, Factory 298 arranged for Chen Dashan and his group to visit their factory.

These days, these are basically standard models.

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

"Leader Chen, although the equipment and equipment here are old, there is absolutely no problem in production. The production process of optical lenses is similar. The only difference is the mastery of some time in the production process and the proportion of various formulas. Although many of these equipment were produced before the founding of the People's Republic of China, a large part of them were also assisted by the former Soviet Union. It has been decades and looks very good. Many of them are much less failure rate than our domestic equipment..." For these old equipment, Xue Dingshan and others cannot say that they are much better than domestic equipment.

Only the problem of small failure rate can be said.

The domestic production of optical glass is already very backward. Even if the Soviet Union aided the New China technology, it was because the Soviet Union itself had not learned it thoroughly and would retain it for the New China. China's technology in this area can be imagined.

Optical glass generally uses furnace blanks to make, melt raw materials, cool to form and chop blanks, and chamfer the blanks. The cut pieces are heated and softened according to the drawing needs and then pressed into the blanks, annealed to remove stress, and detect the performance. Only when the blanks that meet the use are used will enter the grinding process of optical glass manufacturing.

The process seems to be very simple, but this simple process requires a lot of techniques.

"Mr. Xue, what is our material qualification rate?" Liu Yijiu saw that they used clay furnaces, but they did not see that the cost was high, but they could keep the solution stable. They rarely produce bubbles inside the raw materials and traces of veins like water marks left after stirring.

What's more, the platinum furnace has always been recycled. If you don't want the clay furnace, it will be scrapped after using it 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 worse than that of gold. Gold is gold, and platinum is not gold, which is what most people in this world think.

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

When he heard Liu Yijiu ask about the most critical optical glass production pass rate, even Xue Dingshan, who was engaged in technology, smiled bitterly.

"In recent years, after continuously improving the production process, adjusting 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 can only be known after being processed later.

"Why not use a platinum furnace? Although the cost of this kind of 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 ensured to be stable during the melting process. At the same time, it is better than that of a clay furnace when cooling..." Liu Yijiu knew this point about optical glass.

"Comrade 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 girl and it is enough to know some gun design. You are so young, why bother to put on green onions in your pig's nostrils and run here to pretend to be 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 Xue Dingshan in front of them.

They have been exploring for so many years but have not been able to improve. Can this young man who doesn’t know what optical instruments are understand better than them? How can this make them feel good about the old guys who have worked on technology for life?

"Director Xiao, I really have no theoretical basis for this. As for whether anyone uses such a production process, I don't know this. I can't guarantee it if I haven't seen it with my own eyes. However, when I was learning gun design, I heard our teacher say that the top optical glass in foreign countries use small platinum furnaces to manufacture optical glass, so that stable optical glass can be obtained..." Liu Yijiu had to push this to a teacher who he didn't know who it was!

Platinum furnaces make optical glass, which is absolutely true.

"Can the pass rate be increased to 40%?" Xue Dingshan, who was on the side, couldn't help but his eyes lit up when he heard Liu Yijiu's words.

"The specific situation is not clear, but it should be more than 50%. At the beginning, one of our professors mentioned it, but I forgot..." Liu Yijiu knew what they were going to ask next, so he blocked them with words.

"So high!" Xue Dingshan was shocked.

"How is that possible!" Xiao Siwei also found it incredible.

It is impossible for foreign countries to have such a high yield rate! Optical glass is not ordinary glass. In order to disperse the bubbles during the melting process, stirring is required. The bubbles have no defects in dispersing, and the veins like water marks produced by stirring are also defects.

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

It has always been because these defects cannot be solved, so the yield is low. Even in the mid-21st century, there is no way to eliminate defects such as bubbles and pulse patterns. 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 field.

He had no choice.

"If you can achieve such a yield rate, you can experiment. Only the results obtained through experiments are the most reliable." There is no right to speak for Chen Dashan in technical matters. Liu Yijiu dare not guarantee these things.

But he is absolutely sure that optical glass made of small platinum furnaces will definitely be of stable quality than those made of clay furnaces, and the yield rate will be much higher.

"..." The two of them didn't say anything, but they had decided in their hearts that they must give it a try.

Having an idea in my mind, I took Liu Yijiu, Chen Dashan and others to visit the next processing workshop. The production processes of precision component processing, surface treatment and assembly were no longer described in such detail.

"Director Cao, we must have a coating on the scope objective we requested, which is the case outside the Type 62 telescope. After all, sniper rifles need to be used all the time. Especially when performing some tasks, the sniper is likely to lurk in some place for several days..." When leaving, Liu Yijiu emphasized this issue again to Cao Jingui, "Also, in terms of quality, I hope you can make all products meet our requirements..."

The Seventy-Nine Styles back then were due to the quality of the scope, which caused many headaches to the first New China sniper rifle, and basically did not make much contribution on the battlefield. In the end, it was quickly replaced by the Seventy-Nine Styles.

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

A few can guarantee it, but if there are too many, they have no choice.

Once the superiors come to the production task, they often have to hand over a sufficient quantity of products within the specified time!

"Master, can their production environment and equipment provide scopes that meet our requirements?" Even people like Qin Huaibao who do not know much technology are very skeptical about the production environment and conditions like Qin Huaibao.

"If they can't produce it, they probably won't produce it in China." Liu Yijiu sighed helplessly.

There are more than ten domestic optical instrument manufacturing factories, all of which are built with technical support from Factory 298. The best technology is still in Factory 298.

"Xiao Liu, why don't we leave someone here to stare at them?" Chen Dashan whispered with Liu Yijiu when he was about to arrive at the train station, "In this way, once they are done, they can bring back the scope for the sample in the shortest time?"

Chen Dashan was worried that he would not seize the time here.

"This is not good, right? After all, Qin Huaibao doesn't know much about these..." Liu Yijiu couldn't help but hesitate when he looked at Qin Huaibao who was secretly looking at Wang Xinyue from time to time.

He was worried that Qin Huaibao would reveal some secrets of their base in front of the beautiful women. In order to gain a favorable impression on women, men would definitely show that they were different from the men around them. What Qin Huaibao could attract the girls in front of him were the big guys hidden in their base.

A missile like Dongfeng 5 that can hit 8,000 kilometers away can destroy atomic bombs in a big city of the United States. You never have to worry about energy exhaustion and insufficient power plants... These things are absolutely lethal for girls who lack understanding of the whole world now!

Qin Huaibao originally liked Wu Yue, a young nurse with big braids, but how could Wu Yue, who always wears light blue nurse uniforms compare to Wang Xinyue, who is wearing fashion!

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

"It will be much more convenient to leave a resident representative. I hope to manufacture the products we need in the shortest possible time. After all, they don't need to design these scopes..." Wang Dashan is now eager to see a sniper rifle with a scope that can easily kill a range of one thousand meters and appear in his hands.

"Okay! Ask Qin Huaibao first." Liu Yijiu nodded.
Chapter completed!
