"Master, ...... these braziers?"

After Zhang Pan left, Yang Liren came in and asked him.

"Take it and bake it! I still have to go to the workshop, so I don't have time to make a fire. Yang Wenli stood up and walked out, casually replying.

He can't wait to pull himself away now, one person is used as a few people, how can he have time to roast the fire of Laoshzi!

All the people in the "Grand Commander" factory who saw him come in saluted him.

Yang Wenli waved his hand and said: "Don't talk about so many etiquette, it's important to do business, Ru Cheng, arrange a few people to set a reverberatory furnace on fire, and we will do experiments later." ”

"Yes" Wang Rucheng responded, and then found a few Liao people who were temporarily idle and ordered: "You guys go and start the fire, know how to do it!" ”

"Yes, yes!" Several people answered in unison.

After arranging a few people to start the fire, Wang Rucheng walked back to Yang Wenli and asked him, "Great Commander, what are you burning this stove for?" ”

"It's about to be steelmade, I want to test how good the steel is, North Korea's iron ore contains heavy impurities, and the iron and steel they make are not good, but the barrel I want to cast needs very high-quality medium carbon steel, so I have to experiment how to refine the impurities." Yang Wenli explained simply.

"Impurities? What other impurities are in this pure steel? Isn't it all steel? Wang Rucheng, a native of the late Ming Dynasty, heard something strange for the first time, and the general actually said that there were impurities in the steel, and he asked curiously.

"These impurities are invisible to the naked eye, as long as a little bit, the steel quality is very poor, and vice versa. General steel contains silicon, manganese, phosphorus, sulfur and other impurities, of which silicon, manganese these two elements, if the appropriate amount, can make special steel, such as manganese, if the content reaches 3%, the steel will be very brittle, if the content is more than 3o%, it becomes a very excellent high manganese steel.

Phosphorus and sulfur are non-metallic elements, which are very harmful to steel, and I just want to try to remove these harmful impurities. ”

"Phosphorus and sulfur? Is it red phosphorus and sulfur? Yang Wenli spoke too profoundly, Wang Rucheng didn't understand it at all, but he liked to ask questions without shame.

"No, it's phosphorus and sulfur, which are substances that we can't see with the naked eye, and the elements are the basic elements that make up matter, and red phosphorus and sulfur are just one of their material forms." Yang Wenli continued to explain.

"Wow! It's so advanced! How do you know so much, Archon? Wang Rucheng was very surprised by this new knowledge! He was incredible, because there was certainly no book on this knowledge.

"Ahem! I just like to delve into these miscellaneous studies, and if you've been with me for a long time, you'll learn too. After patronizing and talking, he almost showed his stuffing, Yang Wenli thought of an excuse to hold his feet, so as not to be fooled.

In order to prevent Wang Rucheng from asking some questions that are easy to expose, Yang Wenli told him another thing: "Rucheng, these work platforms I want you to make are to let several people work hard side by side, circling around the center point, so this platform must be round, not square, do you understand?" ”

"I see," Wang Rucheng nodded in response.

However, then he asked again: "Grand Commander, what are you doing with such a big platform?" ”

"This is a platform where the two processes of casting the barrel and hot extrusion are combined into one, the barrel needs to bear a relatively large chamber pressure, just casting is not enough, it should have been hot, but now I only want to cast a small cannon barrel, which bears not much bore pressure, and the complex process of hot pressing can be omitted, and I replaced it with hot extrusion."

"Small barrels? Was this helpful? If the cannon is too small, it will not be very powerful. Wang Rucheng did not approve of casting small cannon barrels.

"This is a new type of artillery, very small, one person can take it away, and it shoots a blasting projectile, which explodes when it lands, and the firing degree is very fast, so fast that a flick of a finger can shoot a cannon, and the firing range is also hundreds of steps, and the cavalry impact against Jiannu is completely enough." Yang Wenli explained a little pretentiously.

"What? Is there such a cannon? The Hongyi cannon is also a fart, it is big and bulky, and it can only shoot solid iron balls, cannot explode, and only has a range of a few hundred steps. Wang Rucheng said with wide eyes and disbelief.

"Of course! Don't you see that I don't want those bulky guys, they are removed from the ship, I either don't do it, or I want to do it, or I want to do it, do you see those large casting stands? That's the other cannon I'm going to develop. Yang Wenli said smugly.

"If that kind of small cannon is really that good, in my opinion, the cannon can be dispensed with, the cannon is difficult to carry, and the effect of the small cannon is not necessarily good."

"This is a problem, so for the time being, I will only develop a small-caliber cannon, which is very light and easy to pull by a horse."

……

In fact, the two kinds of guns that Yang Wenli wanted to develop were all based on the small Japanese guns, and the big ones were based on the Type 92 infantry guns, which were the cannons that were most in line with the road conditions in ancient China, and no matter how big they were, they would become cumbersome.

Of course, because of the limitations of ancient conditions, the small cannon he wanted to develop was actually a reference to the imitation of the Type 89 grenadier of the Eighth Route Army Military Factory.

There was no rifling, mortar shells were used, the barrel was lengthened, and a fixed firing pin was used instead of a percussive fire.

There are no other sights or buffer brackets, similar to the Taisho ten-style grenadier in the early days of Little Japan, just a bare barrel, which is shot with the hands on it, all relying on the experience of the soldiers.

Of course, it is very difficult to develop, first of all, the difficulty of the material, the shell body must use high-quality cast iron, that is, gray iron, because it must be tapped by hand, and only cast iron can be processed.

If it is in Dabie Mountain, it is not a problem, the high-quality magnetite ore there, the smelted iron is high-quality gray iron.

But there is no such high-quality iron ore in Liaodong, only scrap iron from North Korea, pig iron ingots, high impurity content, to smelt high-quality gray iron, it is very difficult.

No matter how hard the barrel steel is, it is not simple, and the difficulty is greater than that of gray iron.

The second is smokeless gunpowder and safety primer, both are very dangerous things, although he knows how to do it, but the danger factor is very high, especially the primer, if thundermercury is used, it is not an ordinary danger.

It is dangerous to develop thunder mercury, but the use of thundermercury can use safety explosives, and without thundermercury, you can only use black powder with very little explosive power or nitroglycerin explosives with a higher degree of danger, that thing he dare not step on, the famous Nobel is to develop explosives, and three of his family were killed, and then he was forced to develop safety explosives, that is, diatomaceous earth explosives.

He Yang Wenli only has one life, to be honest, he doesn't dare to develop these things, but in order to successfully reach the top in the future, he must have weapons that are different from others, especially the Western robbers in the future, giant ship cannons, firearms are very sharp, and the black armor army can't fight with bows and arrows, forcing him to only develop these dangerous things.
