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

On the earth, the modern international metallurgical community has no such claims as raw and wrought iron.

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

In ancient China, the iron smelted directly from the iron ore in the blast furnace was called pig iron, and the iron smelted in the iron-smelting furnace (steel-smelting furnace) was called "cooked iron".

The carbon content of this "cooked iron" is inversely proportional to the smelting time. The longer it is fried, the more carbon is oxidized, the lower the carbon content in the iron, and vice versa, so its carbon content can be 0.01%-1.5 Floating between %, it can be said that it contains the "pure iron" and "steel" in the modern sense.

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

It’s just because ancient craftsmanship is difficult to grasp, and has always relied on manpower to operate, so the finished products are mainly iron and low-carbon steel. If you are on **** luck, you may be able to touch One or two pieces of high carbon steel-of course, this probability is similar to the winning rate of the lottery now.

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

The low-carbon steel is soft, so this kind of steel is not very suitable for making 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 weapons. The weapons made of such steel are extremely sharp and hard. Therefore, ancient people think that it is "steel".

The carbon content determines the hardness of the 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, the experienced blacksmith can easily distinguish which piece is soft iron , Which is a good steel that can be made into a sword and a sword.

"Ding Ding Dang Dang........" The voice is endless. At this time, suddenly, a surprise sound came from Gao Yan's side.

"Master, please come and see. The piece I knocked may be fine iron!" an apprentice on Gao Yan's right hand shouted in surprise.

"Oh, let me see!" Gao Yan quickly entered to check.

However, obviously, the apprentice made a mistake in his judgment. After a few taps on the iron in hand, Gao Yan directly said: "Not good enough. This iron is enough to make farm tools like kitchen knives and adzes, but The quality of swords and swords is still far from the same."

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

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

Wang Tie was an apprentice Gao Yan had taken in Qingzhou before. 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, for his apprentice, Gao Yan believes!

"Dang..., Dang..., Dang........." Wang Tie manipulated the hydraulic forging hammer to beat the iron block in front of him. Every time the hydraulic forging hammer struck, the front Sparks spatter on the iron block.

This scene looks very large, as if the iron block in front of it is not very strong, but if you look closely, you will find that the hydraulic forging hammer can't make any deep marks, and the iron block in front of Wang Tie Tough and hard, obviously, this is a fine iron!

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

"Adult, this is real iron. Adult is really Hongfu Qitian. God bless you! It's just that the iron is directly smelted in the first furnace. I have never seen such a thing! Master, God bless you!"

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

"Sir, I don't understand what you said?" Gao Yan said with a puzzled expression, what probability, Gao Yan really didn't understand.

"Gao Yan, before you fry iron, what is the quantity of iron per furnace? I am making iron now, what is the quantity of each furnace?" Lin Ze asked back, then, without waiting for Gao Yan to answer, he went on. Too.

"The amount of iron in my furnace is directly more than 20,000 catties. This amount is ten times, or even twenty times, the amount of iron you made from one iron furnace before. The order of the clips is first-come-first-served. Iron is raw and cooked. It ranges from pure iron to high-carbon steel, so there are always a few pieces of fine iron in it." Lin Ze's face Indifferently explained.

"Oh, that's what it is!" Gao Yan heard Lin Ze's explanation, and suddenly realized.

Indeed, when he made iron before, he threw the pig iron into pieces, and then put it with some charcoal in a much smaller iron-fired furnace than Linze's iron-fired furnace. Then, the wind box used was also human. Bellows, the wind itself is much weaker than it is now.

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

In addition, for iron making like Gao Yan, the quantity at a time is only a few dozen or more than a hundred pounds of iron, and the iron frying furnace here in Linze directly uses the molten iron made by the blast furnace, and the iron is fried for ten thousand pounds at a time, which is quite Because of the iron in more than one hundred furnaces in the past, one or two pieces of steel are directly produced inside, which is really not surprising.

Like Lin Ze just said, it's just a matter of probability!

Thinking of this, Gao Yan finally stopped saying that God blessed him. He stood up very embarrassed first. Then, rubbing his two big hands, he said excitedly, "Master, this piece of fine iron, can you let me come hit?"

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

Lin Ze nodded and said, "OK, then let me see your craftsmanship of the senior master!"

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

"Thank you, sir!" Gao Yan kept thanking Lin Ze, and then, with a happy expression, he picked up the steel ingot on one side, first put the steel ingot on the fire and burned it red, then knocked it down with a chisel The ten-pound piece was finally put under the hydraulic forging hammer and beat.

Gao Yan was in a very good mood at this time. Therefore, he knocked on the fine iron block in his hand while talking to the apprentices around him.

"My method of forging is the use of hundred steels. The swords and swords made by this method can break the gold and cut the jade, even cut off the head and kill the blood. It is an absolute secret technique. Today I will open your eyes!"

After finishing this sentence, Gao Yan devoted himself to manufacturing, and his face became very solemn.

Lin Ze on one side nodded when he saw it.

As long as you look at the appearance of Gao Yan at the time of manufacturing, it can be shown that Gao Yan is definitely a skilled craftsman.

This kind of demeanor, there is no such thing as an ordinary craftsman!

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

At this time, due to the decrease in temperature, the golden-red color of the refined iron had disappeared. Gao Yan put it on the forging furnace and burned it red hot. Then he tapped the chisel in the middle a few times. Then, they folded and folded together from the middle. Finally, Gao Yan put it under the forging furnace and beat.

"Dangdang Dang........." The steel sheet was knocked thin again, folded again, and put on the forging furnace for heating when cold...

Repeated in this way, although this movement seems very boring, but the apprentices around Gao Yan are watching quietly, and everyone is attentive, their eyes have not let go of Gao Yan Any action on the hand.

There are not many opportunities for Gao Yan to demonstrate the secret technique of steelmaking. These students are very aware of this.

In fact, the so-called hundred steelmaking is really easy to explain.

The steel is heated once per furnace, and then beaten once is called one refining. If it is returned to the furnace 100 times and hit 100 times, it is called 100 refining.

Bai Lian is very simple and can be done by anyone who has seen it once. However, it is not that simple to really want to produce Bai Lian Steel.

If you make 100-based steel according to this method, in the end, the people with nine layers and nine will only get a piece of scrap iron, and even many people will have this after 20 and 30. Block steel is scrapped ~www.ltnovel.com~ This is because they don't really master the core technology of hundred steelmaking.

If it is so easy to make steel, the method of it is not difficult. Isn't it all about steel making everywhere, but is it now everywhere? !

Lin Ze didn't believe that the weapons in his army's hands were extremely ordinary iron. Even if it was a general's weapon, the steel-making industry was also a rare horn.

Therefore, 100 steelmaking is not so easy to be refined.

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

This power and frequency is the most important technology of Bai Steelmaking. Generally, people without talents really cannot master the power and frequency inside.

Of course, on the mainland of China, refining 100 steel-making still needs to master the input intensity and frequency of true gas.

After making 100% steel by real gas refining, we can truly be rock-solid and cut gold and jade!
