"Steel? It's very simple. An alloy that uses iron as the main material, contains less than two percent carbon, and contains other metals. This is steel."
Ruanzai looked at Miao Shou who was a little excited and curious, and explained to her.
A few days after the rating controversy of Guang Chengzi and Dui, the latest hot word discussed by people in Hongzhou is "steel".
So-called, how is steel made?
The No. 1 Ironworks is about to open. This huge national wonder building basically represents the highest industrial level in Hongzhou. That’s why many people have sharpened their heads, lost their hair, and are willing to become bald and strong. To dig in, this qualification is really extraordinary.
The National No. 1 Ironmaking Plant is the representative of advanced producers!
A false reputation is useful everywhere. When your reputation grows, people will naturally hire you. When you have a reputation, countless people will naturally seek refuge in you. But in Hongzhou, rating is now reputation, which is not only related to ordinary production and life. Excellent craftsmen can even use this status to help their descendants live a good life.
For example, an extra bag of rice will be given to you during the holidays to help you carry the second floor, or if the exam becomes popular in the future, five points will be added to the exam for the children of ironworks employees...
Similarly, Yu Zai, who was busy in the papermaking workshop, was also asked such questions. After hearing the news from outside, she came to ask Yu Zai, because a few years ago, when she first met Yu Zai, In other words, she knew as early as when her eldest brother stayed up late and worked overtime hammering the plow, that the person in front of her seemed to know everything.
The eldest brother admired him very much, and so did the second brother. Although Changshou himself had not met Yuzai for three years, he did not feel unfamiliar. On the contrary, because he had often interacted with the people of Hongzhou in the past three years, he originally Some little girls who were not good at social interaction became more bold and cheerful.
Of course, Yu Zai knows that he doesn't know everything. If he really carries a portable encyclopedia, he can directly open the technology tree now and complete the industrial revolution in three days to let you know what steel-like power is.
"Things with a carbon content of more than 2% are called pig iron. The properties of pig iron are hard, wear-resistant, and good castability, but pig iron is brittle and cannot be forged."
"Of course, opposite to pig iron, there is something called wrought iron..."
Teoshou widened his eyes slightly:
"Can iron be cooked?"
Yu Zai laughed because of her confusion, but it was normal for the little girl not to understand these things, so she touched her little head to make her happy.
In ancient times, when there were no thermometers, metallographic microscopy, or even the concept of "carbon content," what people called "wrought iron" was actually a very broad concept, from wrought iron in the modern sense to malleable iron. , low carbon steel, medium carbon steel, and even high carbon steel may be included in the concept of "wrought iron".
Because in the hearts of the ancients, "steel" is sacred, only a small part of steel with few impurities and very high hardness will be called "steel" by the ancients and used on the blade. Everything else is "iron".
Ming Shou looked at Yu Zai: "Brother Zai, it's actually strange. Why do you know so much about these things? I haven't seen you strike iron many times. Or are you actually a genius at iron?"
Yu Zai: "Actually, these were all given to me by Chiyou in a dream. He said that his casting skills were so great that he lost to the Yellow Emperor. He was unwilling to give up, so he entrusted all his wisdom to me. I was sleeping that day, and suddenly a bull-headed A man broke into my dream, punched me and knocked me away. Then he grabbed my ears and told me a lot about iron-making. He also said that this was his last method of iron-making. Please accept it. load.....!"
Ruoshou: "???"
Forget it, Azai's nonsense doesn't just happen every day or two, just get used to it.
Teoshou had heard Hongchao say something before. Yuzai seemed to like arranging Chiyou and Huangdi, especially about the four-sided bamboo song...
However, could it be that the reason why Chi You lost to Huang Di was really because the pandas collected Huang Di's bamboo?
I didn't believe it at first, but after thinking about it carefully, it seems to make sense...
Chi You was the first person to make "swords and armors". The first swords and the first armors in the world were made by him by smelting hardware, and he was also an expert at mining... Such a powerful person must be You must have been tricked to death by pandas.
A big drama had already begun to be arranged in the emperor's head. She suddenly felt that if she told her second brother about her idea, the second brother would definitely be able to arrange a fun drama based on this idea.
Of course, the people of Hongzhou must have been very excited to watch it, but Huang Di, the person involved, is also here. It is unclear whether he will shout "refund this rubbish drama" after watching it.
Chief Chang was thinking about the drama of "Panda vs. Zhuolu", and Yu Zai was also thinking about it.
The basis of large-scale steelmaking is actually the output. Handicraft forging and repeated tempering are the methods of hundreds of steelmaking recommended by "Shen Kuo". However, this consumes too much physical energy and is inefficient. The steel that is forged is In fact, the quality also varies.
Therefore, Yu Zai’s method lies in the “steel filling method”.
As for the fried steel method, we are already trying to use it.
The steel filling method was invented in the Eastern Wei Dynasty, which was the era of the Southern and Northern Dynasties. It belonged to the separatist regime of the Northern Dynasties. There was a great figure named Tao Hongjing, who created the steel filling technology.
This technology was still used in some small counties until after the founding of New China, even in the 1970s, 1980s, and even in the 1990s. Even after industrialization, the small workshops and shops that used the steel pouring method were not included. Squeezed to death.
The technology of steel filling method continues to develop, which is the Su Steel method. There are three steel filling techniques. Compared with steel filling, Su Steel method improves the contact conditions of raw and cooked iron. The molten pig iron can move, thus effectively controlling the filling process. leaching to make the composition of the steel more uniform....
Therefore, Yu Zai still knows a little about the methods of frying and pouring steel. She was born in a small county in the countryside. Although she has nothing, she has everything...
Therefore, the wisdom of ancient people is actually very terrifying. When these technologies are concentrated in one era, a technological explosion will be a natural progression. It is like the creation of countless new things all at once during the Yellow Emperor's period. This did not happen overnight, but happened before. There have already been prototypes of many things, accumulated from the three ancient emperors to the era of the Yellow Emperor, and then we ushered in an explosion.
Old technologies and new things bring changes beyond the times.
The corresponding first version of high-temperature steel furnace technology appeared in the Western Han Dynasty. Similarly, higher-grade refractory bricks were also fired in this era. The firing of refractory bricks is not difficult. This was done in the primitive era. Some technology.
