Carefree Prince In Tang Dynasty

Generally speaking, iron is divided into wrought iron and pig iron. The difference between the two is mainly the carbon content.

Everyone who has studied chemistry knows that the "iron" we use in our daily life is not a simple substance of iron, but an iron-carbon alloy. Its nature is far from the true elemental iron. To cite the simplest example, it is almost common knowledge that iron is easy to rust, but in fact, the simple substance of iron, that is, a metal made up of zero-valent iron atoms, actually has considerable corrosion resistance. In other words, it is not easy to rust.

This is because the carbon atoms in the iron-carbon alloy can easily react with the iron atoms to form a galvanic cell, so the oxidation rate of the iron atoms is greatly increased, that is, it appears as rust. In the elemental iron, there are only iron atoms, and its reaction rate with oxygen is very slow, so it is very resistant to corrosion.

Pulled away.

Wrought iron refers to an iron-carbon alloy with a carbon content of less than 0.2%, while the carbon content of pig iron is usually above 2.0%. Because of the difference in carbon content, they exhibit different properties. Simply understood, wrought iron is closer to simple iron, with a softer texture and easy to cast into various shapes, but its strength is insufficient and its application range is not wide. However, pig iron exhibits higher hardness, and at the same time, it has insufficient toughness and is relatively brittle, which is not an ideal material.

Naturally, people should think-if the advantages of pig iron and wrought iron can be combined to obtain a material with hardness and toughness, how good would it be?

Yes, this material is steel. Its carbon content is between 0.2% and 2.0%, and it has both hardness and toughness. It is widely used in many fields. It is casually cast into a sword, that is, a sword that cuts iron like mud and shines. Relaxing is a sword of the level of Juque and Zhanlu.

This is the power of science. The treasures that the ancients exhausted their wisdom and talents and spent a lot of time and energy to make, as long as they have sufficient materials and conditions, they can be mass-produced by scientific methods.

Of course, I have to admit that such mass production is not aesthetically pleasing. However, it is very powerful.

In the past five days, Li Xin took a large group of craftsmen to test the effect of water drainage on the riverside, and by the way, he wanted to find the most suitable steelmaking ratio.

When making iron, water is drained into the blast furnace to blow hot air. Oxygen and carbon are incompletely oxidized to produce carbon monoxide, which reduces the oxidized iron. At the same time, it can also take away excess carbon, reduce the carbon content, and improve the purity of iron.

The blast volume of the water platoon is of course not the same as the old-fashioned man-powered or animal-powered blast of the past. On the first day after the furnace was opened, the iron-making master was shocked by the blower and couldn't help but praise again and again.

Then, the craftsmen were divided into three shifts, began experiments around the clock, and constantly reported data to Li Xin.

Li Xin also doesn't have a calculator, so he can only use his own hands to record one by one on paper with a charcoal pen and calculate the data he wants.

Chen Xinheng once asked Li Xin what he was doing.

Li Xin told him that this was the road to success.

Chen Xinheng rolled his eyes on the spot.

As the saying goes, failure is the mother of success. After not knowing how many failures, Li Xin finally figured out the proper mixing ratio of pig iron and wrought iron, and finally found this perfect way to fill steel. If his calculations are not wrong, the iron that will be released in a while is the steel that everyone dreams of.

In the past, the production of wrought iron and pig iron was done by frying iron, which is the origin of the words "raw" and "cooked". Regardless of how to fry for the time being. Simply put, if you fry a lot, if the carbon content is low, the iron will be more cooked.

The carbon content range of steel is not large. A small difference of one percent may bring about huge fluctuations in the quality of steel. Therefore, it is difficult to fry the steel directly in the process of frying. This is also the origin of the "100-made steel" as the saying goes-ancient swordsmiths must further control the carbon content of the iron block through repeated forging, until it becomes steel.

But now, no need.

Li Xin and Chen Xinheng came to a blast furnace-these blast furnaces were also temporarily forged, and they will all be destroyed in time-a master whose face was flushed with smoke was busy. When the prince came over, he was about to put down the things in his hand to bow, but Li Xin waved his hand, indicating that he didn't need to be polite and concentrate on work.

"How is it?" Li Xin asked.

The master replied: "It's coming soon, it will be done soon."

After a while, the stove was turned on, and orange molten iron flowed out from below, emitting amazing heat, making everyone's pupils bright red.

No difference can be seen by naked eyes. There is only one best way to tell whether the iron material in front of you is the steel Li Xin wants-to use them into weapons.

"Pharaoh, come here, start work!" Li Xin called.

The old blacksmith who often hoeed the villagers separated the crowd and walked over.
