He hey hey smile a face of silly.
Qiu Yuangang wanted to reprimand him for talking nonsense. Su Yonglin raised his hand directly to stop Qiu Yuan.
"Then I’ll give you a direction for this problem, and you should follow this direction to solve the problem well. Now the thickness of the barrel is not thick enough, and the tail is the thickest, and it can gradually become thinner from the tail to the muzzle."
"If it’s white, it’s white, hahaha, so we may really succeed!"
Wang Tietou said, jumping and running in the car.
"This Wang Tietou is so rude. It’s no use talking with your mouth open!"
Qiu Yuan complained a little about his performance in front of Su Yonglin, but Su Yonglin did not care.
"He’s not a courtier pay attention to so many red tape? If the gun-casting craftsman wants to cast the gun well, he has nothing to say. How can he say that the sky has collapsed? "
"So if this experiment is successful, will we not be able to cast bronze cannons?"
Qiu Yuan looked at Su Yonglin.
"It’s not necessary to die like that. It’s not appropriate at all, but even if we have enough copper in our hands, I don’t recommend that the copper cast gun is not easy to explode, but the number of soft shots is more, and the gun body is easily deformed from time to time."
Su Yonglin smiled and shook his head. "It is necessary to have iron. It is the current situation that we don’t seem to have a good iron to withstand the explosion."
Even if my method can’t be successful, I’m afraid I can play it a little bit. If I play too much once or twice, I still have to fry the iron. The quality is not good. This is so good. "
After that, Su Yonglin’s face was full of distress, and he was troubled that he was not a practitioner in the steel industry. He failed to master this technology and could not help anything at the last moment.
"This ….. positions to tell you the truth, the iron that can be cast at present is already the best quality iron. If these irons are used to build weapons, they will definitely be praised by the army."
Qiu Yuan is very confident in his responsible work.
Su Yonglin was noncommittal.
"But the problem has obviously not been solved. I think the main reason is that the temperature is not enough when making iron … Now the main method of smelting iron is pouring steel?"
Qiu Yuan nodded.
"It’s a base or pouring steel method, but it has also made many improvements, which is much better than the previous dynasty."
"But no matter how to improve it, it’s still pouring steel. Before I read Shen Kuo Mengxi’s written talk, I read that Shen Kuo recognized the shortcomings of pouring steel. He said that after two or three smelting, pig iron is still self-cooked and soft iron. It seems that Shen Kuo doesn’t think pouring steel is perfect."
Su Yonglin looked at Qiu Yuan.
Qiu Yuan frowned.
"Should those ministers continue to improve the steel pouring method?"
Su Yonglin nodded.
"In the past, there was no demand, but now we need to bring powerful artillery to the world. It is very urgent that the steel pouring method can’t be refined, but it will be improved.
Once improved, refined iron can be used not only for casting artillery, but also for casting sharper swords, guns and swords, casting stronger shields and armor. This is a good thing in many ways, which is of great significance to sweeping the sky. Qiu Yuan, a piece of iron can change too many things. "
Qiu Yuanshen took a deep breath.
"I know that I will try my best to refine qualified iron!"
Chapter 66 The living can’t be suffocated by urine
Qiu Yuan was determined that Su Yonglin saw it.
He believes that if you want to have your own needs, then Qiu Yuan can definitely take craftsmen to come up with what you need, no matter how much it costs.
However, he needs steel, not to build individual magic swords, not for decoration, but for mass production, which needs a whole set of processes to be strictly controlled.
This aspect involves a lot.
But at least they have this determination, and that is good.
"Well, I can count on you others in this respect."
Su Yonglin thought about it again, and felt that his understanding of steel was limited. He also thought of the Suzhou Iron and Steel Method and some modern ironmaking methods in the middle and late dynasties, such as blast furnace steelmaking.
It is difficult to count on the Suzhou Iron and Steel Process for blast furnace steelmaking, which seems to be the highest technical level of iron smelting in ancient China until the Qing Dynasty.
However, he is not clear about how to improve the Suzhou Iron and Steel Law.
Remember some stars, and staple goods doesn’t know if there are any.
So he thought for a moment with the idea of guiding the craftsmen, and said, "Before I read Mengxi’s written talk, I also read some of his experiences in smelting iron. If you have some ideas, see if it is feasible."
"Go ahead."
"Ironmaking naturally requires high temperature, earlier wood, later charcoal and later coal, and the quality of steel is getting higher and higher. I think the quality of iron should be closely related to the temperature of the ironmaking furnace. Since the coal is not available now, can the coal body do something?"
"Coal? …"
Qiu Yuan thinking up with a frown.
"There will be a furnace ironmaking furnace if bigger higher effect is better? Blower: Don’t blow cold air into hot air. Do something to turn cold air into hot air. Will the fire burn more brightly? Is it hotter in the furnace? "
