This world is very big, with seven continents and four oceans, and people are like ants in it. This world is also very small, so small that two people will meet again in an impossible place.
Lu Da and Xiong Zheng used to be good friends. If he didn't want to contribute to the Anti-Japanese War, Xiong Zheng originally wanted to study abroad. According to the plan, he would stay with Lu Da when he was studying abroad, but he didn't expect , under the arrangement of fate, they will actually meet here!
The reunion of two good friends was also very joyful, and they hugged each other unconsciously.
"Cough, cough." Qin Baoshan on the side coughed twice: "Everyone, just shake hands, don't learn Western etiquette." Qin Baoshan's words were slightly teased. Westerners, kiss when you meet, you two men, don't play Brokeback Mountain.
"Gong Lu, how is your research going?" After seeing Lu Da, he teased a few words, but then turned to an important topic. How is Lu Da's research going?
"Director Qin, the suggestion you made at the beginning is really good!" Lu Da said to Qin Baoshan, "Go, let me show you!"
Aside from the crowd, a few people entered the factory building, and they could see the grenade body processed by the machine tool in the factory building.
On the projectile body, the circles of threads have been processed and formed, but the cut section of the threads presents a special black color, which is quite different from normal white iron.
"According to your suggestion, the combination of the black heart toughening treatment process and the traditional annealing technology is really amazing. In this way, the problem of the fragile projectile body is actually solved. Let's process it in this way. Put the pig iron on the machine tool for processing, and it will not break because it is too brittle, and the processed thread is quite strong." Lu Da said: "We have solved this problem!"
"This, is the grenade used by the grenadier?" Xiong asked right there.
"That's right!" Lu Da said, "At present, in our army, grenade launchers are a very convenient weapon. It¡¯s time to use it, but in the past, we could only use rail steel to process shells, and we couldn¡¯t afford to consume them. Now, we can use white iron produced in large quantities in Taihang Mountains to make them. After process improvement, we are fully capable of processing. Therefore, mass production of this shell has already begun, and according to our current progress, we can produce 5,000 shells for the 50 small guns every month."
Five thousand pieces! This number is quite huge, and it can effectively solve the problem of the supply of shells for the front-line 50 small artillery. The Eighth Route Army is more handy when using this small artillery. At the same time, it also means that the casualties of the troops will be smaller.
In the past, when encountering the enemy's machine gun firepower, there was no other way but to rush up and blow it up with a grenade. What about now? Now use the 50 small cannon, just hide in a safe place and fire!
With the development of the military industry, we will be able to support the frontline battles more effectively!
"If we use rails, we can't afford it." Qin Baoshan said: "5,000 shells need at least a hundred rails. This year, we will need thousands of rails. The rails of the little devil are not so good. Damn, we have to use good steel on the blade."
"Yes." At some point, Liu Daquan had already stood behind Qin Baoshan and said, "Director Qin, it's great that you came back this time. After a year of production, the batch that came The rails are almost used up, and if there are no new ones, it is estimated that all the rails will be used up before the end of this year."
"So fast?" Hearing Liu Daquan's words, Qin Baoshan was also taken aback.
"That's right, we're going to use this batch of rails to make guns, and we're going to use them to make cannons, small cannons, mortars, infantry cannons, all kinds of weapons are being made, and they're going to be used very quickly!" Liu Daquan said. Said.
The rail steel is currently the best steel that our side can obtain. The part that rubs against the train wheels is cut off to make a gun barrel. The other parts are broken into iron plates, and then bent to become the gun barrel. Whether it's a small cannon, a mortar, or even an infantry cannon designed by Qin Baoshan, that is, a rocket launcher, it needs to consume a lot of rail steel. It was consumed at an astonishing speed, transformed into pieces of weapons, and delivered to the hands of the soldiers.
"This is still to manufacture existing equipment. If the rocket launcher is rebuilt, the amount will be even more." Liu Daquan said.
Qin Baoshan came during this period, invented the rocket launcher, and won a battle. These bases also know that the infantry cannon, twelve launch tubes, gun mounts, wheels, etc., all use If it is made of rail steel,The consumption is even greater.
"Yeah, it seems that I am really nervous." Qin Baoshan said, "I have to find a way to solve it."
After finishing speaking, Qin Baoshan looked at Lu Da again. When he saw Qin Baoshan, Lu Da shook his head: "It is not easy to turn pig iron into steel. There is no equipment here, and we can't analyze the composition. This problem cannot be solved temporarily. The cannon steel you mentioned, we haven't started researching it yet."
? When Qin Baoshan was leaving, he had made a bold statement, saying that he wanted to build a real cannon.
Lu Da came back from the Krupp factory, so he has naturally seen how modern cannons are made. Considering the current level of the Huangyadong base, it is still difficult to build cannons. The rocket launchers that do not need to bear the pressure of the chamber are not bad. .
Seeing Qin Baoshan's displeasure, Lu Da continued: "However, we also have some good news to tell you, we have already researched the process of chrome-plating the gun barrel. In the future, even if the barrel is made of rail steel, The lifespan can be more than 10,000 rounds.¡±
After all, rails are not used to make firearms. Although they can be used to make guns with rails, their lifespan is not long, especially the barrel, which has to withstand the pressure of firing and friction with bullets, so the wear and tear is quite large.
The eighty-one type horse rifle currently manufactured, the barrel is completely bald after being loaded with hundreds of bullets. For a bolt-action rifle, it is nothing, but if you want to make a burst weapon, it is like Qin Baoshan's most powerful weapon. The dazzling invention of the assault rifle can't stand the consumption at all. After all, it is a continuous-fire weapon, with hundreds of rounds of bullets, that is, a dozen or so magazines, and it can be wiped out even in one battle.
Therefore, Qin Baoshan proposed the process of chrome-plating the barrel. Unexpectedly, Lu Da came up with this process! (Remember the site URL: www.hlnovel.com
