“Steel? It’s very simple. It’s an alloy with iron as the main material, a carbon content of less than 2%, and other metals. This is steel.”
Yu Zai looked at Ming Shou who was a little excited and curious, and explained to her like this.
A few days after the turmoil over Guang Chengzi and Dui’s ratings, the latest hot word being 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.
If you have 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, we can give you an extra bag of rice during the holidays and help you carry it on the second floor. Or, in the future, if the exam is popularized, five points will be added to the exam for the children of ironworks employees.
Similarly, Yu Zai, who was busy in the papermaking mill, was also asked this kind of question. 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, as did the second brother. Although the emperor 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 are not good at social interaction have become 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 castable, but pig iron is brittle and cannot be forged.”
“Of course, opposite to pig iron, there is something called wrought iron”
Oshou’s eyes widened slightly:
“Can iron be cooked?”
Yuzai laughed because of her confusion, but it was normal for the little girl not to understand this, 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 would be called "steel" by the ancients and used on the blade. The rest are all "iron".
Tao 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 iron-making method. Please accept it.
load!"
敤头:“???”
Forget it, Azai's nonsense is not something that happens every day or two, just get used to it.
I heard Hong Chao say something before. Yu Zai seemed to like arranging Chi You and Huang Di, 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 had collected Huang Di’s bamboo?
Originally I didn’t believe it, 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 both made by him. He was also a very good mining expert. He must have been tricked to death by pandas.
Bar.
A big play had already begun to be arranged in the emperor's mind. She suddenly felt that if she told her second brother about her idea, the second brother would definitely be able to make up a fun play based on this idea.
Of course, the people of Hongzhou must have been very enthusiastic about watching it, but the person involved, Huang Di, was also here. It is unclear whether he would shout "refund this rubbish drama" after watching it.
敕头 was thinking about the drama of "Panda vs. Zhuolu" in his mind, and Yuzai was also thinking about it here.
The basis of large-scale steel-making is actually the output. Handicraft forging and repeated tempering are the methods of hundreds of steel-making advocated 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.
So, the method used is the "steel filling method".
As for the method of frying steel, 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 invented 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
So I know a little about the methods of frying and pouring steel. I was born in a small county in the countryside. Although I don’t have anything, I have 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 Yellow Emperor's period when countless new things were created at once. This did not happen overnight, but happened before.
There have already been prototypes of many things. From the time of the Three Ancient Emperors until the time of the Yellow Emperor, they ushered in an explosion.
Old technologies and new things have brought 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.
