Chapter 158: Construction of a steel mill
After getting up, Lu Bu felt that the yin and yang were harmonious and his spirit was refreshed.
Under the service of Diao Chan and Zhang Ning, I got up and had breakfast. After thinking about it, Lu Bu was about to meet Huang Chengyan and Huang Yueying.
I have been tricked into others for more than a month, and I have been busy with this and that, and I have never had time to see them. It is really a shameful thing to say.
By the way, there is Hua Tuo...
Fortunately, I have excerpted some Western medicine theories for Hua Tuo. Hua Tuo is now studying them with relish, but he still can't argue them.
Well, after going to meet Huang Chengyan today, I have to meet Hua Tuo.
Soon, Lu Bu came to the house arranged for Huang Chengyan.
Without letting his disciples inform him, Lu Bu walked in directly.
When he walked into the yard, Lu Bu found Huang Chengyan watching the excerpts from Lu Bu for him. There was also some basic knowledge of mathematics in modern physics and chemistry, and he was watching it with relish.
Hearing the footsteps of Lu Bu, Huang Chengyan couldn't help but put down his book and stood up, bowed his hand and said to Lu Bu: "I don't know if the prefect has arrived, I will be in a position to welcome you. I will forgive you for your crimes!"
Lu Bu said dissatisfiedly: "Mr. Chengyan, shouldn't you be so arrogant?"
Then he said apologetically: "Mr. Chengyan, I've been busy this month and I haven't taken time to pay my respects. I'm so neglected. I hope you don't take it to heart."
Huang Chengyan couldn't help but laugh and said, "Why did Prefect Lu say this? I see the achievements made by Prefect Lu over the past month. Prefect Lu is a good official who truly seeks welfare for the people! What is the point of neglecting me, an old man alone?"
At this moment, when Huang Yueying heard Lu Bu's voice, he hurriedly ran out of the house.
Seeing Lu Bu, he was so excited that he couldn't help but jump into Lu Bu's arms, hugged Lu Bu's legs, and said coquettishly: "Brother Lu, you haven't come to see Yueying for so long. Do you hate Yueying?"
Huang Chengyan couldn't help but smile bitterly and said, "Premier Lu, you don't know. This little girl ran to your prefect's mansion and asked for it, but she had never seen you. This month, this girl has been pouting and being depressed. If you don't come again..."
Huang Yueying couldn't help but smell: "Dad!"
Lu Bu couldn't help but apologize: "Yueying, Brother Lu said sorry to you, it's not that Brother Lu doesn't want to see you. I'm so busy that I haven't been home a few times this month."
Huang Yueying said understandingly: "Brother Lu, Yueying knows that you are busy, Yueying won't be angry with you. That's right, they really miss you!"
Lu Bu couldn't help but stroke Huang Yueying's little head and said, "Okay, Yueying, your brother Lu is almost busy now. Can you come and play with you if you have time?"
Huang Yueying couldn't help but clapped her hands happily and said, "Okay, OK, Brother Lu, don't lie to me!"
Lu Bu laughed and said, "How could this prefect deceive the child?"
Huang Yueying stomped her feet and said dissatisfiedly: "Brother Lu, she is not young anymore!"
Huang Chengyan smiled beside him and said, "Prefect Lu, please sit down and talk."
Lu Bu sat down and said seriously: "Mr. Chengyan, just call me Fengxian, it's better not to call me the prefect!"
Huang Chengyan said seriously: "This is one time and another. If I directly call the word "Premier Lu", it would be inappropriate to spread it."
Seeing that Huang Chengyan insisted on calling him the prefect, Lu Bu did not persuade him again.
Lu Bu said to Huang Chengyan: "Mr. Chengyan, I came here this time to ask Mr. Hunter to take charge of steelmaking. I wonder if Mr. Hunter is interested?"
The level of steelmaking during the Three Kingdoms period was just beginning. Because the technology and temperature did not meet the standards, the iron could not be fully dissolved into iron, and could only be burned into something like a very soft iron paste.
Then put the pig iron into the iron paste and pound it continuously, and remove the impurities in the steel bit by bit by bit by bit.
The highest craft at this time was called "Hundred Steel Fencing", which means that it takes nearly a hundred beats to finally take shape.
A piece of cooked steel with ten kilograms can weigh up to two kilograms after hundreds of tempering.
Not only does it waste steel, but the refining speed cannot be improved at all.
It is simply impossible to equip a large number of steel-making weapons in the army.
However, if Lu Bu's method is followed, iron ore is dissolved at high temperature, and impurities such as thiophosphate in the molten iron are removed, and a certain amount of carbon is added.
If you add more carbon, you will be hard and brittle high-carbon steel, and if you add less, you will be soft and elastic low-carbon steel.
The steel refined in this way can be directly cast weapons, and there is no need to be as complicated and laborious as forged steel.
If you want to fight for the world, improving the level of steelmaking is an indispensable thing.
Therefore, Lu Bu was going to hand over this matter to Huang Chengyan.
...
However, Huang Chengyan was obviously not very happy to do steelmaking.
Huang Chengyan couldn't help but say to Lu Bu: "Prefect Lu, you can actually leave it to others for steelmaking..."
The implication is that if you leave it to him, it will really be a burial of talent.
Lu Bu couldn't help but smile and said, "Mr. Chengyan, it is not that easy to make steel. You know, it takes a lot of tempering to make steel. However, if the furnace temperature can be raised, the iron ore can be completely melted into molten iron, and the impurities inside are directly removed in the molten iron state, the effect of making steel without the need for a lot of tempering can be achieved!"
"Also, adding charcoal into the steel can change the characteristics of the steel. If you add more, the steel will become hard and brittle. If you add less, the steel will become tough. If you master this ratio, you can make the most suitable steel for flexibility and hardness!"
"Through steelmaking, you can master a lot of knowledge. I believe Mr. Chengyan has also seen this chemical foundation. Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, argon, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, calcium. In these steels, sulfur and phosphorus elements exist. Does Mr. Chengyan know how to remove these two elements from the iron?"
Hearing this, Huang Chengyan's eyes couldn't help but lit up.
The books that Lu Bu gave to Huang Chengyan were like pushing a door open in front of Huang Chengyan, and a brand new world was presented to Huang Chengyan.
The reason why Huang Chengyan is unwilling to accept the steelmaking is because Huang Chengyan can't wait to get to know and understand the new world more.
However, Lu Bu's words made Huang Chengyan feel that what he learned in books will always be at the theoretical level.
Only by practicing and operating it yourself can these things be truly transformed into your own.
Therefore, Huang Chengyan finally agreed to Lu Bu's request.
Seeing Huang Chengyan agreeing, Lu Bu couldn't help but be overjoyed, and then explained in detail various details of steelmaking to Huang Chengyan.
Warehouse, blast furnace, smelting chamber, molten pool, furnace, blowing system, etc.
