Chapter 28-Amelioration of Bullet Craftsmanship! Steel wrapped copper!
Factory Manager Hao and the others looked at Su Yan and fell into deep thought. Everyone who was celebrating the success of the new gun quieted down at this moment, afraid to disturb Su Yan.
The group of Soviet military experts at the side were also looking forward to it.
In their opinion, copper was irreplaceable as a raw material for the production of bullets.
First of all, the hardness of copper was relatively low, and the requirements for processing technology were lower. Other metals often needed high temperatures to achieve molding, and copper's temperature requirements became its advantage.
Materials with a high ignition point would naturally have poor thermal conductivity. If a bullet wanted to be fired, it would generate kinetic energy through friction, thereby igniting the gunpowder in the bullet.
If the thermal conductivity of the bullet was not good, it was very likely that it would misfire.
In addition, there was a large reserve of copper on the blue planet, and the cost was low!
Therefore, copper had become the most mainstream material for bullets on Blue Star.
But unfortunately, the copper reserves on the blue planet were very high, but there was very little copper in the rabbit territory!
In a region like Shanbei, which was rich in mineral reserves, although there were copper mines, they were small in scale and low in reserves!
If Rabbit wanted to mass produce bullets, he could only rely on the import.
But now, the conditions of the rabbit were very difficult. There was no money to import large quantities of copper to produce bullets.
In the end, he still had to rely on the hairy bear's assistance!
However, if B. Rabbit wanted to ask the hairy bear for help, there was a lot to be done!
Copper, this is another price!
In the eyes of the experts, even though Su Yan was a genius, he couldn't go against the objective laws. Without the raw materials, no matter how imaginative his ideas were, they wouldn't work!
The bear specialists were all waiting for Su Yan to give up, and then they were ready to make an offer for the rabbit.
While the beardy experts were secretly rejoicing, Su Yan put down the AKM in his hand, looked around at everyone present, and said,"I have an idea."
Have you thought of a solution?
Ye Linna and the bear experts were stunned and looked at Su Yan in disbelief.
How was this possible?
Factory Manager Hao and the others were excited. They didn't expect Su Yan to have a solution.
"Comrade Little Su, don't keep us in suspense. Quickly tell us what method it is.”
Su Yan picked up a bullet and smiled."It's actually very simple. Since we can't change the main material of the bullets and copper is indispensable, we can change our way of thinking and reduce the amount of copper used!”
Before Su Yan could finish, Lin Jianjia had already handed him a draft paper. The two of them had already formed a tacit understanding. Even if they didn't speak, they could understand each other's thoughts.
Su Yan took the draft paper and drew the shape of a bullet on it.
Everyone gathered around and saw that Su Yan had only drawn a regular bullet. They didn't understand what he meant.
Su Yan saw that everyone was confused, so he immediately drew a thin layer on the bullet.
"This is…"
"Steel clad copper."
Su Yan pointed at the bullet on the blueprint and said,"The bullet is made of steel, and a layer of copper coating is wrapped around the bullet. This can solve the problem of insufficient raw materials and solve the technical shortcomings of our arsenal.”
"You mean, copper?"
Factory Manager Hao thought for a moment and actually felt that Su Yan's words seemed feasible?
If it was just copper coating, the copper consumption was completely within the range that the rabbit could bear. As long as the coating was slightly thicker, the shape of the bullet could be completed.
"In this way, we can perfectly solve the problem of bullet production.”
Ladle copper was a commonly used method of producing bullets, and it was also the optimal solution obtained after countless experiments.
Not only did it perfectly solve the problem of the flower family's lack of copper, but the bullets made of this alloy were also more precise and had a stronger penetrating power.
The thermal conductivity of copper could be used to fire the bullets, while the lighter steel would allow the bullets to have a longer range.
It seemed feasible to put it away, but Manager Hao thought about it and realized that ladle copper also needed technical support.
Although it was just a layer of copper on the surface of the steel bullet, the process required was also very complicated.
Would the rabbit's skills work?
After all, the characteristics of these two materials were different. It was also a technical job to make these two materials fit perfectly together!
"I already have a preliminary idea. I call this the solid-phase binding method.”
Su Yan immediately drew on the paper again. Through high-temperature plastic transformation, the joint of the two metals was close to the distance of atoms, and then a large number of joint points were formed.
After the initial heat-spreading process, a firm bond was formed.
When they heard Su Yan explain the principles of chemistry on the paper, the workers present were confused and did not know what he was talking about!
Factory Manager Hao and the political commissar looked at each other. Didn't this kid go out to study mechanics? How could he know chemistry?
And in such a short period of time, he had come up with a solution!
Looking at the dumbfounded expressions of the group of bear experts opposite him, Factory Manager Hao knew that this kid's method was definitely feasible and even quite useful!
The mouths of those bear-like military experts were long enough to fit an egg.
"Forget it, I'll just tell you the process.”Su Yan sighed when he saw the confused look on everyone's faces.
If it was in the future, this ladle copper technology would not be considered a very difficult high-end technology. It was even widely used in various fields. However, in this era, this was undoubtedly a new technology that no one had ever heard of!
"That's right, Su Yu, we're all boorish people. We wouldn't understand even if you told us that! Just tell us what to do!”
Elder Chen said cheerfully.
Since Su Yan had a way to solve it, no matter how difficult it was to produce it, they had to overcome this hurdle!
"It can probably be divided into the steps of pre-molding, surface treatment, and warm-up. The production line would be able to complete the following steps.”
Su Yan thought for a moment. However, if it was copper-clad steel, there was no need for explosive welding. Moreover, Mao Xiong's equipment was advanced enough. As long as the materials were completed, the subsequent processes could be completed with the equipment of the production line.
"Actually, the most difficult step is the first step. You need to make the mold in advance, and the precision of the mold needs to be very high.”Su Yan thought about it. If the mold could achieve a value of 7.62, the subsequent processing should be much easier.
"That's not a problem. There are a few old workers in our factory.”Manager Hao thought about it. For the few technical backbones in the factory, this was not a difficult thing.
In this way, the problem of the bullets was almost solved. Moreover, Su Yan's new technology could be used to promote it to the entire army!
The production capacity of the Munitions Factory would probably increase by leaps and bounds!
