Online game of Jinyiwei

Chapter 2146 Artillery
Although Tie Hammer was a player, it didn't happen. Those big craftsmen and everyone looked down on him. Tie Hammer followed Zeng Yi not long after the game started, and he was always in the capital. Yi made a thorough investigation in the blacksmith shop in the capital, especially the eunuch in Dongchang, who was very polite to the hammer, but he knew that the hammer was a master craftsman who could make artifacts.Originally, Zeng Yi thought that everyone looked down on the hammer and then slapped him in the face, but now he can't see it.

"Hammer, that's all, come and see, what's wrong!"

Iron Hammer didn't talk nonsense, and observed directly in front of those artillery pieces. After a few glances, he immediately said: "The material is not good enough, the purification is not enough, and the other is the pouring technology." He said and looked at the master craftsmen, "You are using Clay as a mold for casting?"

Those master craftsmen nodded immediately when they heard the words. "Is there a problem?"

"The problem is serious!" In ancient times, clay was generally used as a casting mold for early casting, but the clay mold had very high requirements on the humidity, composition and casting technology of the soil, not to mention that the finished mold had to go through It can only be used after drying, so it often takes several months or even half a year for a good mold to be formed.You should know that the clay mold is one-time, the success rate is very low, and the inside of the finished gun bore is often uneven, which is why it is very easy to explode the bore.

Hearing the words of Tie Hammer, the complexions of those master craftsmen became a little ugly, the third child looked at the crowd, and whispered in the ears of Zeng Yi and the other three: "Second brother, did you make a mistake? How can you be a great craftsman at this level? You can’t even compare to a blacksmith who makes hoes, right?”

The fourth child rolled his eyes at the third child, "Are you stupid? They are all masters in shipbuilding and weapons. They used to study things like ballistas, and most of them were wooden ship-borne weapons. There are steel parts, but also a very small part, for casting technology, of course, you can't keep up with the guy with the hammer!"

These master craftsmen can pick it up and put it down, although they are embarrassed, but they are still very respectful to the hammer and said: "Please give me your advice, sir!"

As a craftsman himself, Tie Hammer naturally had no other objections to the craftsman, and immediately said: "You are welcome, since I am here, I will naturally do my best, let's take it step by step!"

"Sir, please come in!"

Everyone came to the factory together, and the hammer looked at everyone, "Let's start with the material! Such a large utensil can't be forged, but can only be cast. You use steel as soon as you come up. You know, the temperature of the furnace is high. If it is not too high, the forged pig iron will be too brittle, the wrought iron will be too soft, it will be difficult to control the melting point, there will be more air bubbles, and the structure will be simple, and these problems will naturally occur!"

"Then what material should I use?"

"Use copper!" Although these master craftsmen are not very good at casting, they still understand the basic techniques. When they hear copper, all eyes light up. "Hey! We're all in a dead end!"

"Using copper is relatively simpler. I believe you all understand that the material problem has been solved. Then let's talk about the mold. No matter what material you use, as long as you use clay, these problems will definitely occur. I suggest using steel to make it." Molds! Iron molds can be used repeatedly, and the cast barrels are naturally smooth, with less trachoma and high quality.”

"Didn't you say iron? Go on, I'll shut up." Before Zeng Yi finished speaking, he was stared back by Iron Hammer.

"Use the best materials and the best technology to make a set of molds, even if you do it bit by bit, as long as you get it out, the subsequent production will be much easier!"

Tie Hammer deserves to be a master-level blacksmith. He was taken aback by what the NPCs said, but at the back, several master craftsmen said to Tie Hammer respectfully: "I hope you can help me!"

Seeing that Hammer hesitated, both Dengzhou Navy and Eunuch Zhang of Dongchang made a request. After Zeng Yi repeatedly reminded him of the blueprints of the magic weapon and the casting technology, Hammer agreed to help.

"I can make a shot, but the mold must be made of very good steel, not to mention Damascus steel or jade steel, it must be similar."

"Coincidentally, the last time I came back from Persia, I brought back a batch of high-quality steel from Persia, and I can use those!" Zeng Yi immediately bought the batch of steel that he had bought to cover his identity at twice the price. Sold to Dengzhou Navy Shipyard.

Speaking of forging, the fourth child is really good. With the help of more than a dozen master craftsmen and dozens of ordinary craftsmen, Iron Hammer made the mold in less than a day. Finally, after a series of The rotten workmanship, the mold was finally made out.

"The mold is ready, can it be used to cast cannons?" Everyone asked impatiently.

But the hammer said: "It's only preliminary, and it still needs to be polished!" The hammer is a very skilled weapon polishing technique. Under his command, those craftsmen almost polished and polished the mold into a mirror. .

"It's all right now, let's start casting the cannon!"

The hot copper water was poured into the mould, and everyone waited anxiously. As the time passed, they all looked at the hammer. After a while, the hammer said, "Open the mould!"

As the mold was opened, a brand new copper cannon appeared in front of the crowd. When the copper cannon was not so hot, those master craftsmen rushed up and started to operate it. In order to polish the inner chamber, those master craftsmen actually found The craftsmen who polished the copper mirror worked together for several hours, and the inner surface was polished like a copper mirror.

At this point, the bronze cannon was finally cast, and the governor of the Dengzhou Navy immediately ordered the experiment to start. The freshly baked cannon was quickly pulled to the shooting range.Because of the explosion in front of the chamber, several people have already died. This experiment can be said to be very careful.

The ammunition used by the artillery is still stone bullets, polished like a ball.Loading, igniting, firing, and with a loud noise, the cannon that everyone was looking forward to finally fired its first shell.

As the shells were fired, there were two expressions on the faces of the people present. On the one hand, the NPCs all showed smiles on their faces, and on the other hand, Zeng Yi and the others all frowned.

"Why so close? It shouldn't be, it's not much different from the Ballista!"

"But it's powerful!" said a craftsman beside him.

"No, it shouldn't be such a small distance. What kind of cannon is only more than 200 steps away!"
