Chapter 94 (1/2)
Ferguson watched with his own eyes the smashed pig iron slowly melt into yellow and white liquid iron in this big pot made of ”mud”. The expression on his face was wonderful.
”Is that ok? Oh, MAIGA! How can such a pot melt the broken iron? Guardian, did you cast any magic
Stone bear glanced at Ferguson and said gently, ”call boss and I'll tell you how to do it.”
Lieutenant Ferguson was silent immediately.
Then, Lieutenant Ferguson saw that the molten iron was scooped out and poured into the mold which had been heated all the time. What made Lieutenant Ferguson most excited was the next words of stone bear.
”Patrick, do you know how to make steel? Don't underestimate this pot of molten steel. After cooling, this is the steel with better material. In the future, if you want to make a rifle with longer range and greater power, casting barrel is a skill you must master. After all, the barrel is the core of a gun. Without a barrel of good quality, a rifle with great power and long range can only be utopian. ”
In the meantime, after pouring the mold, there is still a lot of liquid steel in the crucible, so Shi Xiong is ready to let the remaining liquid steel cool naturally.
Lieutenant Ferguson looked constipated. Although he saw the whole process of steelmaking, he didn't understand some key details. If you really cast the barrel alone in the future, you can't trouble the guardian every time.
But at the thought of what the guardian said just now, the constipation on Lieutenant Ferguson's face became heavier
The next day, the gun barrel that had been completely cooled and the remaining molten steel formed a steel lump after cooling were all removed.
Stone bear took a piece of pig iron to grind the steel lump, revealing the color of the steel lump itself. It was really that clean silver white.
This color already explained is a good steel! Stone bear hit with a hammer a few times, found that the toughness of this steel lump is also very good, so he was completely relieved.
The barrel is made in one pot with this steel lump. Even if this barrel is absolutely unqualified in later generations, it is absolutely the top barrel in this era.
Sure enough, when the mold was broken open, a one meter long steel pipe with a diameter of about 16 mm appeared in front of the public.
Stone bear took aim with his eyes and found that the barrel was still very straight. Although there is no level instrument and other tools when making the mold, stupid people have stupid methods. The simplest hanging wire method is used, and its straightness is not worse than that measured by level instrument.
When Shi Xiong made the mold at that time, whether it was the outer mold or the kaolin mold in the center of the barrel, it was made with several hanging wires, so the straightness was naturally guaranteed.
He handed the barrel to Ferguson, who thought about it last night, so his eyes turned red and his dark circles came out this morning.
However, the spirit of this guy seems to be very good, especially after taking the barrel of the gun, he looked carefully for a long time, and then knocked the barrel with another piece of iron. After listening to the voice, he said: ”guardian, this is really a very good barrel. At least I didn't see any defect in this barrel, and I can judge that this barrel is much better than the one on me! ”
”Are you sure?”
