- "Steel? It's very simple. Iron is the main material, the carbon content is less than 2%, and this alloy contains other metals. This is steel."
Yan Zai looked at the somewhat excited and curious Yanshou, and explained to her in this way.
A few days after Guangchengzi Hedui's rating turmoil, the latest hot word among people in Hongzhou is "steel".
So-called, how is steel tempered?
The opening of No. 1 ironworks is imminent. This huge national-level wonder building basically represents the highest industrial level in Hongzhou. That's why many people have sharpened their heads and shaved their hair. They don't hesitate to become bald and stronger. If you want to drill inside, this qualification is really extraordinary.
Guozi No. 1 Iron Works is the representative of advanced producers!
Fame is very useful in any place. When you have a big reputation, people will naturally hire you. With your reputation, countless people will naturally join you. In Hongzhou, the rating is now the reputation, which is not only related to ordinary production and life. Excellent craftsmen can even use this status to make their descendants live a good life.
?For example, give an extra bag of rice during the holidays to help you carry the second floor, or the exam will be popularized in the future, and five points will be added to the exam for the children of ironworks employees
Similarly, Yuzai, who was busy in the paper mill, was also asked this kind of question. After hearing the news from the outside, she came to ask Yuzai, because from the first time she saw Yuzai a few years ago, In other words, as early as when her elder brother stayed up late and worked overtime to knock on plow tools, she knew that the person in front of her seemed to know everything.
The elder brother admired him very much, and the second elder brother was the same. Although he himself hadn't met Yan Zai for three years, he didn't feel unfamiliar. Some girls who are not good at socializing have also become more bold and cheerful.
Of course, I know that I know, I don¡¯t know everything, if I really carry a portable encyclopedia, I will directly open the technology tree right now, complete the industrial revolution in three days, and let you know what steel-like power is.
"Things with a carbon content greater than 2 percent are called pig iron. The performance of pig iron is hard, wear-resistant, and good castability, but pig iron is brittle and cannot be forged."
"Of course, as opposed to pig iron, there is something called wrought iron"
Ye Shou slightly widened his eyes:
"Can iron be cooked?"
Yan Zai laughed because of her confusion, but it is normal for the little girl to not understand these things, so she touched her little head to make her happy.
In ancient times when there were no thermometers, metallographic microscopy techniques, or even the concept of "carbon content", what people called "wrought iron" was actually a very wide 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".
The head looked at Yan Zai: "Brother Zai, it's actually very strange, why do you know this so much? I haven't seen you hit iron many times, or are you actually a genius for blacksmithing?"
Concubine Zai: "Actually, these were all given to me by Chi Youtuomeng. He said that he lost to the Yellow Emperor because of his excellent casting skills. He was not reconciled, so he entrusted all his wisdom to me. I was sleeping that day when suddenly a bull's head Someone broke into my dream, punched me flying, and then grabbed my ear and said a lot of things about ironmaking, and said that this is his last ironmaking method, please accept it load!"
”¨Í·: "???"
Forget it, it's not a daily thing for Ah Zai to talk nonsense, just get used to it.
? I heard some things Hongchao said before, Yuzai seems to like to arrange Chiyou and Huangdi, especially about the four-faced bamboo song
However, is it true that Chiyou lost to Huangdi because the panda took Huangdi's bamboo?
At first I didn't believe it, but after thinking about it, it seems very reasonable
Chi You was the first person to make "sword armor". The first sword and the first pair of armor in the world were made by him, and he was also a small expert in mining such a powerful person must be He was killed by a panda.
In the head of the head, a big play had already begun to be arranged, and she suddenly felt that if she told her second brother her idea, the second brother would definitely be able to make a fun play according to this idea.
Of course, the people of Hongzhou must have been very excited to see it, but the person involved, the Yellow Emperor, is also here.It is not known whether he will yell "return money for rubbish drama" after watching it.
The chief executive is thinking about the drama of "Panda vs. Zhuolu" in his head, and Yan Zai is also thinking about it here.
The basis of great iron and steel smelting is actually the output. Handicraft forging and repeated tempering are the hundred steel smelting techniques that "Shen Kuo" admired, but this consumes too much energy and is inefficient. The forged steel is In fact, the quality is also uneven.
Therefore, the method of confinement lies in the "steel pouring method".
As for the method of frying steel, it is already being tried.
The method of pouring steel was invented in the Eastern Wei Dynasty. It was the era of the Northern and Southern Dynasties and belonged to the separatist regime of the Northern Dynasties. There was a cowhide character named Tao Hongjing, who created the steel filling technique.
This technology was still used in some small counties after the founding of New China, even in the 1970s and 1980s, and even in the 1990s. Squeeze to death.
The technology of pouring steel method continues to develop, which is Sugang method. There are three kinds of steel pouring techniques. Compared with steel pouring, Sugang technique improves the contact conditions of raw and wrought iron. Drenching, so that the composition of the steel is more uniform
Therefore, Yu Zai still knows a little about the method of frying steel and pouring steel. She was born in a small county in the countryside. Although she has nothing, she has everything
Therefore, the wisdom of the ancient people is actually very terrifying, and when these technologies are concentrated in one era, the technological explosion will be a matter of course, just like the Huangdi period created countless new things at once. This did not happen overnight, but before There are already many embryonic forms of things, accumulated from the three emperors of the ancient times to the era of the Yellow Emperor, and this ushered in an explosion.
? Old technology, new things have brought about 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 is the original era. There are technologies.
