The so-called "wrought iron" that has been beaten is not actually wrought iron in the sense of modern textbooks. Pen % fun % Pavilion www.biquge.info

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

In the modern iron and steel industry, the carbon content is less than 0.02%, which is called wrought iron in China, and pure iron in foreign countries, because this type of iron is very soft, and the carbon content is 0.02%-2.11% is called steel, and the carbon content is more than 2.11% in Huaxia is called pig iron, and in foreign countries it is called cast iron.

In ancient China, pig iron was smelted directly from iron ore in a blast furnace, and wrought iron was smelted in a steel furnace.

The carbon content of this "wrought iron" is inversely proportional to the frying time, and the longer the frying, the more carbon oxidizes, the lower the carbon content contained in the iron, and vice versa, so its carbon content can continue to float between 0.01% and 1.5%, which can be said to include 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 because the ancient process is difficult to grasp, and has always relied on manpower to operate, so, the finished product is mainly iron and medium and low carbon steel, if you go on the shit luck, you may also be able to meet one or two pieces of high-carbon steel - of course, this probability is similar to the current lottery winning rate.

Generally speaking, the lower the carbon content of steel products, the softer they are, and the higher they are, the more brittle and hard they are.

Medium and low carbon steel is soft, so it is not very suitable for such steel to make swords, because the weapons made of such 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, and weapons made of such steel are extremely sharp and hard, so the ancients thought that it was "steel".

The carbon content determines the hardness of steel, so an experienced blacksmith can easily tell which piece of steel is soft iron and which piece of steel can be made into a sword by the appearance of the steel when it is struck with a forging hammer and the sound of the steel when it is struck.

The sound of "jingling ........" was endless, and at this time, suddenly, a surprise and unusual sound came from Gao Yan's side.

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

"Oh, I'll take a look!" Gao Yan hurriedly walked in to check.

However, obviously, the apprentice's judgment was wrong, and after Gao Yan knocked the iron with his own hand a few times, he said directly: "It's not good, this iron is enough to make kitchen knives, adzes and other farm tools, but it is still far from the quality of fighting knives and swords." ”

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

"Oh, is it?" 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 had been an apprentice under Gao Yan for nearly five years.

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

Therefore, Gao Yan believes in this apprentice of his own!

"When... While.... , when ........!" Wang Tie manipulated the hydraulic forging hammer to continuously knock on the iron in front of him, and every time the hydraulic forging hammer struck, sparks would sputter on the iron in front of him.

This scene seems to be very large, as if the iron in front of him is not very strong, but if you look closely, you will find that the hydraulic forging hammer can't knock out how deep the imprint, and the iron mass in front of Wang Tie is tough and hard, obviously, this is the best fine iron!

"This, this is real fine iron, real fine iron!" Gao Yan knelt down directly to Lin Ze excitedly, and his voice trembled.

"My lord, this is real fine iron, my lord is really blessed with heaven, God bless! It's just that the first furnace of fried iron directly smelted fine iron, I have never seen such a thing! My lord, God bless!"

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

"My lord, I don't understand what you said?" Gao Yan said with a puzzled face, what is the probability, Gao Yan really doesn't understand.

"Gao Yan, when you fried iron in the past, what was the quantity of iron per furnace? Now I am making iron, what is the quantity of each furnace?" Lin Ze asked rhetorically, and then, without waiting for Gao Yan to answer, he continued.

"The amount of iron in a furnace is directly more than 20,000 catties now, such a quantity is ten times or even twenty times the amount you got from making iron in a furnace before, so much iron, the order in which the workers clamp out of the iron furnace is first and last, and the iron is raw and cooked, from pure iron to high-carbon steel, so there are always a few pieces of good fine iron in it. Lin Ze explained indifferently.

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

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

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

In addition, Gao Yan's iron-making is only a few dozen or more than a hundred catties of iron at a time, and Lin Ze's iron-frying furnace here is directly using the molten iron smelted from the blast furnace, and the iron is fried tens of thousands of catties at a time, which is equivalent to the iron of more than 100 furnaces in the past, so it is really not surprising that one or two pieces of stainless steel are directly produced in it.

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

Thinking of this, Gao Yan finally stopped saying anything God blessed, he first stood up very embarrassed, and then, rubbing his two big hands, said excitedly: "My lord, can you let me fight this piece of fine iron?"

Gao Yan looked at Lin Ze expectantly, and his heart was stupid/stupid/desired/moving!

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

Lin Ze will have a lot of this kind of steel in the future, so it is not rare in his heart at all.

"Thank you, thank you, my lord!" Gao Yan kept thanking Lin Ze, and then, happily, picked up the steel ingot on the side, first put the steel ingot on the fire and burned it red, and then knocked off a piece weighing about ten catties with a chisel, and finally, he directly put it under the hydraulic forging hammer and beat it.

Gao Yan was in a very good mood at this time, so he talked to the apprentices who gathered around him while knocking on the fine iron block in his hand.

"My forging method, what comes out is a hundred steel, after such a hundred refining methods made of swords and swords, you can cut gold and jade, and even cut off the head and kill people without blood, it is an absolute secret skill, today I will let you open your eyes!"

After saying this, Gao Yan devoted himself to manufacturing, and his face became extremely solemn.

After Lin Ze on the side saw it, he nodded in his heart.

As long as you look at Gao Yan's appearance when he is manufacturing, you can show that Gao Yan is definitely a skilled craftsman.

Such a bearing, the average craftsman, will not have it at all!

"Dangdang Dang ........!" the fine iron was constantly beaten by the forging hammer, and soon, it became a thin piece.

At this time, because of the decrease in temperature, the golden red color of the refined iron had faded, Gao Yan directly put it on the forging furnace to burn it red-hot, and then knocked the chisel in the middle a few times, and as soon as the iron tongs were forced, they were bent and stacked together from the middle, and finally, Gao Yan was put under the forging furnace and beaten.

"Dangdang Dang .........!" the steel sheet was knocked thin again, folded again, and when it was cold, it was put on the forging furnace to be heated......

It was repeated like this, although this action looked boring, but the apprentices around Gao Yan watched quietly, and everyone was attentive, and their eyes did not let go of any movement in Gao Yan's hand.

There are not many opportunities for Gao Yan to demonstrate the secret technique of 100 steel, and these apprentices know this very well in their hearts.

In fact, the so-called 100 steel, if you really explain it, is also very simple.

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

Hundred refining is very simple, as long as you have seen it once, you can do it, but it is not so simple to really want to refine hundred steel.

If you refine 100 steels according to the method of 100 refining, in the end, the people of the 9th layer will only get a piece of scrap iron, and even many people have already smelted this piece of steel after 20 or 30 refining, all because they have not really mastered the core technology of 100 steel.

If 100 steels are so easy to refine, and the method of 100 smelting is not difficult, then isn't there 100 steels everywhere, but now there are 100 steels everywhere?!

Lin Ze didn't believe it, he didn't see that the weapons in his army's hands were all extremely ordinary iron, even if it was the weapons of some generals, the hundred steels were rare.

Therefore, 100 steels are not so easy to refine.

If you want to refine the real 100 steel, you also need to master the power and frequency of refining.

This power and frequency is the most important technology of 100 steelmaking, and people who generally have no talent really can't grasp the power and frequency in it.

Of course, on the Shenzhou Continent, refining 100 steels also requires mastering the input strength and frequency of true qi.

After the 100 steels refined by true qi, they can truly be as solid as a rock, cutting gold and breaking jade!
