Liu Zheng walked quickly, with a look of joy on his face.
Zheng Yueru was also excited. Recently, this "God's Workshop" has become the most mysterious place in the eyes of Yinzhou people. The four major families have sent many people here to find out the news. However, the place is heavily guarded and all the scouts have failed.
And return.
Who would have thought that Liu Zheng would take the initiative to invite her to observe, how could she not be excited?
Along the way, there were all twists and turns, and the workshops were clearly separated. When passing by the brewery, Zheng Yueru wanted to take a closer look, but seeing that Liu Zheng did not stay again, she could only follow Liu Zheng to the backyard.
"Jingtiefang"!
This is Liu Zheng's newly established workshop. The ordinary cast iron of this era can no longer keep up with his needs. Of course, it is still unrealistic to achieve real steelmaking.
But fine iron can!
The iron-making method of the Longyan Dynasty is still a relatively primitive iron-making method. The iron ore is melted at a high temperature of 1000 to 1200 degrees and flows out to become cast iron. The cast iron is hard but brittle and basically useless in actual use. Therefore
In order to obtain fine iron, people in this era can only use one method, forging!
The craftsmen heat the pig iron until it is close to melting, and then repeatedly forge it to remove impurities such as carbon, sulfur, and phosphorus. If the time is long enough, a piece of steel will be obtained. If the pig iron is repeatedly forged, a piece of low-carbon steel will be obtained, which contains very few impurities.
Made of steel, the ancients called it hundred-smelted steel, which is refined iron. It is considered the best among irons. If it is forged again, you will get wrought iron, which the ancients called soft iron.
This method of steelmaking is very time-consuming.
During the Three Kingdoms period, Cao Cao wanted to forge five hundred steel swords, which took him three years.
But even this kind of soft iron cannot meet the requirements Liu Zheng wants!
Plate armor has really high requirements for steel.
then.
Liu Zheng, a science student, naturally transformed the craftsmanship of the fine iron workshop. On the one hand, he taught these craftsmen how to use blast furnaces to make steel!
On the other hand, it is block-smelting carburized steel!
The principle is actually very simple. During the multiple heating and forging processes, the lump of iron comes into contact with charcoal, and the carbon continuously penetrates into the iron, increasing the hardness of the iron block, forming what is called block-smelting carburized steel. Carburized steel is used to make weapons and
Tools, whose performance is comparable to bronze, have practical value.
Throughout the entire Chinese civilization, some people have made this kind of steel by mistake, but because they did not know what the principle was, they did not popularize it.
However, Liu Zheng understands these principles!
It’s just the carbon content that affects hardness and flexibility.
The combination of these two methods not only greatly accelerated the speed of steelmaking, but also directly improved the quality of steel a lot! Of course, Liu Zheng was not a steelmaker in his previous life, so he could only fiddle with it, so here he is
After half a month of staring, I finally succeeded!
"this......"
"What is this place? Is this iron smelting?"
Zheng Yueru, at this time, was already frightened by this fine iron workshop, and she immediately exclaimed.
How had she ever seen steel-making in a blast furnace?
The sparks are flying, the heat is intense, the busy craftsmen, the flowing molten iron, flowing from one blast furnace to another, and the various processes are perfectly connected. Where is it that one person is still holding a hammer and knocking around?
The picture of the small workshop makes people’s eardrums hurt.
"Bring me the plate armor quickly!"
Liu Zheng laughed loudly.
Lu Dachui had already brought this set of plate armor, and Liu Zheng's eyes lit up when he saw it.
Zheng Yueru looked strangely again: "Brother Liu, what is this again?"
She just felt that this guy, who was known as the number one dude in Liangzhou, was becoming more and more difficult to see through.
"Walk!"
As soon as Liu Zheng touched this set of plate armor, he felt that something was going on, and walked towards the courtyard with a few people. Zheng Yueru was so depressed that she could only follow him.
In the courtyard, some soldiers were already standing there.
Liu Zheng looked at their fierce eyes, nodded with satisfaction, threw the plate armor to one person, and ordered him to put it on.
"armor?"
Zheng Yueru said in disbelief.
How can these pieces of things be used as armor? What can they protect?
At this time, Liu Zheng had already brought a steel knife from the side, and asked Zheng Yueru with a smile: "Miss Zheng, how do you like this knife?"
Zheng Yuru likes to be a man, so she is naturally good at practicing martial arts. She held the knife in her hand, and her eyes lit up: "It's a good knife, it can be used to cut off hair!"
Liu Zheng thought to himself that this is a sword made from my refined iron, how could it be any worse?
He chuckled, pointed at the soldier who had already put on the plate armor and said: "Miss Zheng, chop him down!"
