Chapter 441: Chrome Plating

Previous page        Return to Catalog        Next page

    Qin Baoshan originally wanted to say that Lao Maozi¡¯s Bobosha¡¯s pipe was chrome-plated, and the AK¡¯s pipe and piston were also chrome-plated, but thinking about it, let¡¯s forget about the first two, and the latter two are really shocking, so  So he stopped talking.  You kid has never seen it, how would you know?  Moreover, the last one has not yet been born.

    Therefore, Qin Baoshan can only continue to say other reasons: "After the gun is chrome-plated, it will reduce the ablation of the propellant inside the barrel, increase the hardness of the inner bore of the barrel, and increase the life of the barrel.  , the pipe used in humid climates does not grow rust and is easy to use. It is much more advanced than the technology we are using now, and it is the most suitable way to increase the performance of guns."

    After finishing speaking, he glanced at Liu Daquan again, and said, "Master Liu, this is element No. 24 in the periodic table of elements. It was first discovered by the French. The biggest feature of this element is its hardness."

    Lu Da's mood at this time, I don't know whether to describe it as shock or what. You know, in this era, chrome plating is only a secret that a few companies can grasp. As for the benefits of chrome plating on guns, it is even more important.  It has not been accepted by the public. It can be said that in this era, chrome plating for firearms is only a preliminary exploration and has not been popularized. It was after the end of World War II that the Soviets' ak  The series of rifles is the most typical of them. Due to the chrome plating process on the barrel and gas piston, the reliability of this gun has been greatly improved, and it has finally become a generation of gun kings.

    If one's own assault rifle cannot use chrome plating, it cannot become a truly advanced rifle.  This process is a must.

    Lu Da stopped talking, and his brows began to frown. It seemed that his brain began to work rapidly. Lu Da kept thinking about something in his mind. After waiting for five minutes, he said, "There is no chrome.  .¡±

    Obviously, at this moment, he considered everything in his brain and left useful information. After thinking about the whole process, he got such an answer.

    Speaking of the process of chrome plating, he is confident that it can be done, but without chrome, how to do chrome plating?  It's hard for a clever woman to cook without rice.

    In the whole country, there is no chromium mine, and there is no chromium production factory. Lu Da got such an ending, and the technological processes just thought of are useless.

    "Yes, there is no chromium now, but it doesn't mean there will be no future." Qin Baoshan said: "We can mine by ourselves. In the past, we didn't have copper, didn't we find copper mines too? Hard work pays off, as long as you want it  There is always something to look for, even if we can¡¯t find it in the end, we can still ask Big Brother to borrow it.¡±

    The reason why the Soviets were able to use a large amount of chromium plating technology is because the Soviet Union has the largest chrome ore in the world, so first look for it from the country. If you can¡¯t find it in the country, you can borrow it from the Soviet Union.  On the barrel, there are four coatings thick, which is only 0.04mm. A piece of metal chrome the size of a fist is enough for thousands of rifles. Don't worry too much about this kind of thing.

    Qin Baoshan put forward his own opinion, which was completely feasible, so Lu Da finally nodded.

    A smile appeared on the face of the brigade commander. Now, the Eighth Route Army is becoming more and more formal in making guns. If with this kind of technology, a rifle with a lifespan of thousands of rounds, or even tens of thousands of rounds is produced, that would be amazing.  It's amazing.

    "Brigade Commander, so, um, the matter of prospecting" Qin Baoshan looked at the Brigadier again.

    "The higher authorities will deal with it." The brigade commander immediately responded, you boy, you want to find this excuse to slip away, but there is no way, besides, your luck is really good, the new mission, finally  It's already down, this time, I don't think running broke your kid's two legs!

    "Let's solve the problem of white cast iron first." Lu Da said, "For our base, this problem is the most important, right?"

    The barrel is chrome-plated, and it can¡¯t be done without chrome, so let¡¯s do other things first. In the base, everything is on the right track, and the only problem left is the shells of the 50 small guns.

    Qin Baoshan nodded: "That's right, Mr. Lu, I will leave this matter to you. Our base has sent several smart and strong technicians to help you."

    Lu Da nodded. At this time, he had already walked to the workshop. He saw that the rifle was being blackened by the local method to prevent rust.  Although this anti-rust method is rustic, it really solves the problem. Let¡¯s solve the problem of white cast iron. In my opinion, we can also use a combination of local and foreign.¡±

    Lu Da is a high-achieving student, a professional student who returned from studying abroad.?, I have drank foreign ink, but he did not appear superior because of this, but he paid great attention to the local production method here. Although it is rustic, it can solve problems. Any operation reflects the thousands of years of Eastern  The unique craftsmanship and the wisdom of the working people passed down from the ancient civilization.

    It was also for this reason that he chose to come here to help.

    "A combination of local and foreign?" The brigade commander clapped his hands there: "Okay, how about a combination of local and foreign?"

    "I am in Germany. I have carefully studied the toughening treatment process, and then combined with our traditional annealing technology, it should be able to solve the problem of the fragility of the projectile body and achieve the goal of machining threads on the lathe."

    Toughening treatment is a basic steel treatment method. Pig iron is relatively brittle and can be regarded as a low-quality steel. However, after toughening treatment, it can even reach the level of casting engine steel. The automobile engines of later generations are almost all  Pig iron casting is the reason for this process.

    Lu Da had already talked about the specific research plan. After hearing his words, Qin Baoshan suddenly remembered an article he had read in his previous life. As a technical school student, Qin Baoshan's research  It is very wide, and he remembers it very clearly. In that article, it described the difficult exploration process in Liugou Iron Works. Although it was usable at the beginning, it was still not easy to use. It was not completely solved until the later stage.

    Among them, there are two key words, white heart toughening technology and black heart toughening treatment, but which one is right?

    I really can't remember this clearly, but Qin Baoshan knew that the toughening treatment used at the beginning was a detour.

    "Mr. Lu, what toughening treatment do you plan to use?" So Qin Baoshan asked.

    "Of course it's the white heart toughening technique. I didn't expect you to even know this?" Lu Da looked at Qin Baoshan strangely.

    Therefore, Qin Baoshan nodded naturally: "I have heard of some, if this technology is not up to standard, maybe you can try the black heart toughening treatment." (Remember the website website: www.hlnovel.com
