The so-called "wrought iron" that has been beaten is not actually wrought iron in the sense of modern textbooks.

On the earth, there is no such thing as raw and wrought iron in the modern international metallurgical circle.

In the modern iron and steel industry, those with a carbon content of less than 0.02% are called wrought iron in China, and pure iron abroad, because this type of iron is very soft in texture; the carbon content is between 0.02% and 2.11%. Those with a carbon content of more than 2.11% are called pig iron in China, and cast iron abroad.

In ancient China, what was smelted directly from iron ore in a blast furnace was called pig iron, and what was smelted in a frying iron furnace (steel frying furnace) was called "wrought iron".

The carbon content of this "wrought iron" is inversely proportional to the frying time. The longer the frying, the more carbon oxidation, the lower the carbon content in the iron, and vice versa, so its carbon content can be between 0.01% and 1.5% It can be said that it contains all the "pure iron" and "steel" in the modern sense.

To sum up, in ancient times, frying iron was equal to frying steel.

It's just that the ancient technology is difficult to master, and it has always been operated by manpower. Therefore, the finished products are mainly iron and medium and low carbon steel. If you are lucky, you may be able to touch it One or two pieces of high carbon steel - of course, this probability is about the same as the current lottery winning rate.

Generally speaking, in steel products, the lower the carbon content, the softer it is, and the higher it is, the more brittle and harder it is.

Medium and low carbon steel is soft, so it is not very suitable to use this kind of steel to make swords, because the weapons made of this kind of steel are not sharp, so the ancients also regarded it as "wrought iron".

Only the toughness, hardness, and strength of high-carbon steel meet the needs of making weapons. Weapons made of such steel are extremely sharp and hard, so the ancients thought it was "steel".

The level of carbon content determines the softness and hardness of steel, so through the external performance of the steel when it is struck by a forging hammer, and the difference in the sound of the steel when it is struck, experienced blacksmiths can easily distinguish which piece is soft iron , Which one is a good steel that can be made into a sword.

"Ding Ding Dang Dang..." The sound was endless, at this time, suddenly, a pleasantly surprised voice came from Gao Yan's side.

"Master, come and take a look, the piece I knocked may be fine iron!" An apprentice on Gao Yan's right hand exclaimed with surprise.

"Oh, let me take a look!" Gao Yan quickly walked in to check.

However, obviously, the apprentice made a mistake in his judgment.

After Gao Yan knocked the piece of iron with his own hands a few times, he said directly: "It's not good, this iron is enough to make kitchen knives, adzes and other agricultural tools, but it is still not as good as the quality of swords and swords. far."

At this time, Wang Tie on Gao Yan's right said calmly: "Master, can you take a look at this piece of iron? I think it is a piece of refined iron! (Refined iron is steel!)"

"Oh, is that so?" Gao Yan quickly came to Wang Tie's side, with a look of expectation on his face.

Wang Tie was Gao Yan's apprentice in Qingzhou before, and he has been Gao Yan's apprentice for nearly five years.

This time there was a rebellion in Qingzhou, and Wang Tie also ran out with Gao Yan.

Therefore, Gao Yan believed in his apprentice very much!

"When..., when..., when...!" Wang Tie manipulated the hydraulic forging hammer to continuously hit the iron block in front of him. Every time the hydraulic forging hammer struck, the iron block in front of him Sparks will fly from the iron block.

This scene seems to be very big, as if the iron block in front of him is not very strong, but if you look carefully, you will find that the hydraulic forging hammer can't make a deep mark, and the iron block in front of Wang Tie Tough and hard, obviously, this is the best refined iron!

"This, this is real refined iron, real refined iron!" Gao Yan knelt down to Lin Ze excitedly, his voice trembling.

"My lord, this is real refined iron. My lord is truly blessed and blessed by the gods! It is just the first furnace of frying iron that directly smelts refined iron. I have never seen such a thing! My lord, God bless!"

"Hehe, it's not God's blessing!" Lin Ze said indifferently: "Gao Yan, it's not surprising that such refined iron appeared in the first furnace, it's just a probability!"

"My lord, I don't understand what you are saying?" Gao Yan said with a puzzled look on his face. Gao Yan really didn't understand the probability.

"Gao Yan, before you smelted iron, how much was the quantity of iron in each furnace? Now I am smelting iron, how much is the quantity in each furnace?" Lin Ze asked back, and then, without waiting for Gao Yan's answer, he continued. up.

"The amount of iron I have in one furnace now is directly more than 20,000 catties. This amount is ten times, or even twenty times, what you obtained in one furnace of iron smelting before. With so much iron, the workers get it from the iron furnace. The order of clipping out is first and then, and the iron varies from raw to cooked, ranging from pure iron to high-carbon steel, so there are always a few pieces of good refined iron in it." Lin Ze looked Explained calmly.

"Oh, so that's the case!" Gao Yan suddenly realized after hearing Lin Ze's explanation.

Indeed, when he smelted iron before, he first hammered pig iron into pieces, and then put it together with some charcoal into a frying iron furnace that was much smaller than Lin Ze's frying iron furnace. Then, the bellows he used were also manpower. The bellows, the wind itself is much weaker than the current one.

Because the wind is weak, it will inevitably lead to a longer burning time, and a long burning time will inevitably lead to a decrease in the quality of the pig iron, so the quality of the refined iron will be lower.

In addition, Gao Yan's ironmaking is only a few dozen or a hundred catties of iron at a time, while the iron frying furnace here in Lin Ze uses molten iron smelted directly from the blast furnace, and it can fry tens of thousands of catties at a time, which is quite a lot. Compared with the more than one hundred furnaces of iron in the past, it is really not surprising that one or two pieces of fine steel came out of it.

Just like what Lin Ze said just now, it's just a matter of probability!

Thinking of this, Gao Yan finally stopped talking about God's blessings. He first stood up in embarrassment, then, rubbing his two big hands, he said excitedly: "My lord, can you let me do this piece of refined iron?" beat?"

Gao Yan looked at Lin Ze expectantly, feeling stupid/stupid/desire/moving in his heart!

Lin Ze nodded and said, "Okay, then let me see your craftsmanship, Master Gao!"

Lin Ze will have a lot of such steel products in the future, so he is not rare at all in his heart.

"Thank you, my lord, thank you, my lord!" Gao Yan kept thanking Lin Ze, and then, with a happy face, he picked up the steel ingot on one side, first put the steel ingot on the fire and burned it red, and then knocked out about A piece weighing ten catties was finally put directly under the hydraulic forging hammer to be hammered.

Gao Yan was in a very good mood at this time, so while knocking on the refined iron block in his hand, he started talking to the disciples who surrounded him.

"My kind of forging method, what I strike out is hundred-refined steel. After this kind of hundred-refined method, the sword and sword can cut gold and jade, and even beheaded, killing people without blood. It is an absolute secret skill. Today I'll let you open your eyes!"

After saying these words, Gao Yan threw himself into the production with all his heart, and his face became extremely solemn.

After Lin Ze saw it, he nodded inwardly.

Just looking at Gao Yan's appearance when making it, it can be seen that Gao Yan is definitely a skilled craftsman.

Such a magnanimity, the average craftsman will never have it!

"Dang dang dang...!" The fine iron block was continuously hit by the forging hammer, and soon it became a thin piece.

At this time, due to the drop in temperature, the burnt golden red color of the refined iron has faded away. Gao Yan directly put it on the forge to burn it red hot, and then tapped the center a few times with a chisel. , they were bent from the middle and stacked together. Finally, Gao Yan put them under the forge and beat them.

"Dangdangdang...!" The steel sheet was knocked thin again, folded again, and when it was cold, it was placed on the forge to be heated...

Repeatedly like this, although this kind of action seems very boring, but the apprentices around Gao Yan watched quietly, and everyone was attentive, their eyes did not let go of Gao Yan any movement of the hand.

There are not many opportunities for Gao Yan to demonstrate the secret skill of hundred steel smelting, and these apprentices know this very well in their hearts.

In fact, the so-called 100-year steelmaking, if it is really explained, is also very simple.

Every time the steel is heated in the furnace, it is called one refining, and it is called a hundred refining when it is returned to the furnace a hundred times and beaten a hundred times.

Hundred refining is very simple, as long as someone who has seen it once can do it, but it is not that simple to really want to refine hundred steel.

If you refine the hundred-smelting steel according to the hundred-smelting method, in the end, the people on the ninth floor will only get a piece of scrap iron, and even many people have already put this piece of iron after 20 or 30 smelting. A piece of steel was scrapped because they didn't really master the core technology of steelmaking.

If Baisteel is so easy to make, and the method of Baisteel is not difficult, then wouldn't Baisteel be everywhere, but is Baisteel everywhere now? !

Lin Ze didn't believe it. He didn't see that the weapons in his army's hands were all very ordinary iron. Even the weapons of some generals were made of steel.

Therefore, Baisteel is not so easy to be refined.

If you want to refine the real hundred-smelting steel, you need to master the power and frequency of refining.

This power and frequency are the most important techniques in Baisteelmaking. Generally, people without talent really can't grasp the power and frequency well.

Of course, on the mainland of China, one needs to master the intensity and frequency of infuriating energy input in order to refine hundreds of steels.

Only through the hundred-smelting steel refined with true energy can it truly be as solid as a rock, cutting gold and cutting jade!
