"This, chief, we haven't been developing this technology for a long time, and it's still being tested. And this aspect is still unstable, so we need to study it more. Jiang Chen said with a smile.

"You don't give me sloppy eyes. Deputy Director Song stared at Jiang Chen and said angrily: "I sue you, I am going to decide this technology, what can you do with me." ”

"You're a hard robber. Jiang Chen was full of black lines.

"I'll rob it, what can you do. Deputy Director Song said proudly.

"Then you grabbed it, the main technology of this thing is the formula of this high-strength ceramic, and now there are very few people who know about it, and it just so happens that I am one of them, do you think you can get what you want from me?" Jiang Chen looked at Deputy Director Song and said fearlessly.

Hearing Jiang Chen say this, Deputy Director Song's eyes widened and then glared at Jiang Chen, this action made the people around him hold their breath and dare not speak. After a long while, Deputy Director Song relented, then looked at Jiang Chen and said, "Say, what conditions do you have." ”

"Hehe, this is not in a hurry, this is not in a hurry, let's look at something else first. Jiang Chen said with a smile.

Seeing Jiang Chen say this, Deputy Director Song had no choice but to diǎn the head.

With Jiang Chen's gesture, Li Gongyou began to introduce: "With things like ceramic brake pads, we also have this ceramic brake disc." Compared to traditional iron steel brake discs, this ceramic brake disc weighs nearly half as much as a conventional iron steel brake disc. This means that lighter brake discs mean less weight under suspension. This makes the suspension more responsive and thus improves the overall handling of the car. In addition, ordinary brake discs are prone to thermal decay due to high heat under full braking, while ceramic brake discs can effectively and steadily resist thermal decay, and their heat resistance effect is many times higher than that of ordinary brake discs. There are also ceramic discs that generate maximum braking force immediately at the beginning of braking, so there is no need for a brake assist system. The overall braking is faster than the traditional braking system, the distance is shorter, in order to resist the high heat, there is ceramic between the brake piston and the brake pad to insulate the heat, the ceramic brake disc has extraordinary durability, if the normal use is life-long replacement, while the ordinary cast iron brake disc is generally replaced after a few years. ”

Looking at the scorching eyes of the members of the delegation, Li Gong shuddered and then hurriedly followed (1)±dǐng(1)±diǎn(1)± Xiao(1)± and said, .♂.o←s_(); continued: "Still. At present, this ceramic brake disc is still in the process of being developed. Because it is much larger than the ceramic brake pad, which makes its overall strength still have a lot of improvement, so in this regard, we still need more room for improvement. ”

Seeing everyone's heads, Li Gong breathed a sigh of relief and continued: "Look here, these pieces are the engineering plastics we developed. Compared with some previous engineering plastics, it is more rigid, less creep and has higher mechanical strength. Better heat resistance and better electrical insulation. It can be used for a long time in more demanding chemical and physical environments, and can replace more metals as engineering structural materials. The parts you see are some of the parts of the car that we use engineering plastics to produce, because it performs well under various conditions, so many of our products are replaced by engineering plastics. Also, if you look at the block, this one represents the highest level of crystallization here. The new assault rifles and pistols developed by the B17 factory, including light machine guns and sniper rifles, are made of this engineering plastic. And because it's lightweight. High strength and high temperature resistance. Corrosion resistance and other characteristics, in the real yàn, has achieved very good results. ”

"Oh?" Deputy Director Song turned his head to Jiang Chen, as if asking Jiang Chen about this. Seeing this, Jiang Chen then said, "It's used, this material is really yàn room." It not only undertook the materials related to our company, but also undertook the research and development of the related materials of the B17 factory. At present, the latest type of firearm we are developing is developed using this material. The same gun, made of engineering plastics, is almost a kilogram lighter than the old one. And the overall performance remains the same, and even rises a little. ”

"Well, I'm looking forward to your new product. Deputy Director Song looked at Jiang Chen and said with a smile: "By the way, how is the development of that small-caliber rifle going?" ”

Jiang Chen looked around and said, "Well, it's already started, and seven or eight plans have been proposed. It's a bit complicated, and I'll report back to you another day. ”

Deputy Director Song said, "This is not in a hurry, let's continue to visit." ”

"Okay. Li Gong diǎndiǎn head said: "Please go this way." ”

With that, everyone followed Li Gong out of here and came to this metal material research area. Looking at several individual factories and buildings, Li Gong now said to everyone: "This is the largest and most important area of our entire material room, and a lot of achievements have been made so far. The products you saw before have a shadow of this. ”

Li Gong pointed to those buildings and factories and said: "It's just that it's so big, it's not that we have a large scale or a lot of people, but in fact, this equipment covers a relatively large area." The buildings you see are basically where we store our materials and furnaces. The capacity of these furnaces is very small, ranging from a few hundred kilograms to a few tons, and the largest is thirty or forty tons. We have a total of seven here, in addition to our new three new intermediate frequency furnaces, vacuum furnaces, and electric arc furnaces. There is also a shaft furnace and a reverberatory furnace, as well as two electroslag remelting furnaces of different capacities. In addition to the development of various metal materials, we also produce some special materials ourselves. ”

"Oh, you still produce your own products, won't it 、、、" The Tu Yuan soldier didn't say it, but everyone present knew what he was trying to say. So Jiang Chen took Li Gong's words and said, "Actually, it's like this. The amount of this special material we need is very small. And there are very few factories that can be refined in China, and the road is far away, and it is too much to toss back and forth. The second is that the refining and production of this part of the materials and parts is very difficult, and the cost is relatively large, and some materials must be processed by using the refining equipment we have here at this stage. So as a result, no factory is willing to take this order, because the number required is relatively small, so they all feel that the investment is not worth it. So we ended up proudly producing ourselves. ”

Seeing that Jiang Chen finished speaking, Deputy Director Song looked at Jiang Chen and said with a smile: "There is still one diǎn you didn't say, I'll add it for you, you are afraid that the recipes and refining methods of these materials will leak out." ”

"Hehe, we have to eat too. Jiang Chen said with a smile. (To be continued.) )
