If you don't say that it's not a family that doesn't enter the door, they and Hu Er are the same mode of thinking, whether they make money or not, put it aside first, as long as they can learn advanced skills, they won't starve to death.

Looking at the Wujin Xing next to them, they knew that they would definitely not starve to death, so what are they waiting for, one more family will have more strength, and it is best to let their brothers learn all the skills, and no longer pass them on to others.

Hong Tao now has no energy to choose who is suitable and available, and he is not afraid of any family members playing tricks with him. These technologies are not familiar to them for a while, and they are expensive and of little use.

Industries such as coking and blast furnace ironmaking are difficult for private individuals to play without state procurement and support, and the source of raw materials and product sales alone can make people worry to death.

You said that you make iron to produce agricultural tools and sell them, but after the quantity reaches a certain level, the imperial court will not sit idly by, and will immediately have to supervise it. Because this thing, like tea, is a strategic material of the country, and it must be controlled by the imperial court.

The smelting industry in the Northern Song Dynasty was still in a state of semi-governmental, semi-non-governmental, and the imperial court allowed private mining and private smelting, because the official power alone was not enough to meet all the needs, and the private sector was a useful supplement.

However, once this kind of clay blast furnace appears, the amount of ironmaking will suddenly soar, and private capital will definitely not be able to compete with the government, and the state will no longer need to use private enterprises to supplement the lack of production capacity.

"Are you all ready?" The martial arts family, like the Hu family, is also a father who takes his son into battle together, passing on his skills and experience at the same time, when there is nothing to teach, the older generation should basically die, and the next generation is still like this.

The master of the earth blast furnace is naturally the second eldest in the martial arts, he is almost sixty years old, and his waist is not very good, and he was the one who wheeled the sledgehammer wheel when he was young. But when it comes to big things, the old man has to be on top, and he is not at ease with others.

"All prepare to stop according to the instructions of the officials, today is a good day and an auspicious day, just wait for the officials to order, after slaughtering and sacrificing, you can open the furnace and make a fire!"

Unlike Hu Er, the samurai regarded iron smelting as a sacred cause, especially when the new furnace was fired, sacrifices must be held, otherwise it would not be practical, and they were always worried that the gods would sin and cause something wrong.

"You go and get your hands on it, find someone to take me to see the iron in the furnace." Hong Tao couldn't convince these people, so he could only let them simplify the procedure as much as possible and make two sheep meaningful.

I definitely don't want to participate, but I have to see the stacking situation in the blast furnace in person. It's not that they don't worry about the samurai, but they are afraid that there will be errors in communication, after all, they have only been here for a short time, and they are not used to their way of speaking.

"Brother Wang, would you like to go with you?" Wang Shao didn't come by himself, his son Wang Hou has always been by his side, that is, the second child who has a little experience in weapon manufacturing and iron smelting.

Specifically, Wang Hou is not interested in knowing how much Hong Tao knows about smelting, he can watch it if he wants to, and it doesn't matter if he can understand it or not. As long as the furnace is turned on for six hours, the iron will be produced, and there is no evidence for it, so let's take the real thing as proof.

Wang Hou is five or six years younger than Wang Xu, a black-faced man with a tiger's back and a bear's waist, not tall and stocky. He has traveled with Wang Shao since he was a child, and later joined the army together, it can be said that he has experienced all the wars commanded by his father, and he has been influenced by war since he was a child, so he naturally chose to join the army and did not take the path of a literati.

It is impossible to judge how much military attainment he has, but according to common sense, it should not be too bad. Fighting this thing is actually practice makes perfect, and if you have been exposed to it since childhood, a lot of military literacy has become instinct. As long as there is no problem with IQ and there are major flaws in personality, at least he is a qualified middle- and lower-level officer.

"Lord Duwei, please ......" is consistent with his appearance, Wang Hou's personality is not too public, he doesn't talk much, he seems to be easy-going, but his eyes are bright.

Since he arrived at the construction site, he has not been idle, he has not left behind those who can understand and those who can't understand, but he has never asked any questions. This patience alone made Hong Tao admire, if it was for himself, he would have to ask all the less.

Every time Hong Tao went to Wang Shao's mansion to change the medicine, Wang Hou basically took his fourth brother to receive him. After nearly ten days of contact, the two are already acquaintances, but it is difficult to further their personal relationship, because their personalities do not match. One is uncomfortable if he doesn't speak, and the other is uncomfortable if he says too much.

"Do you know this furnace?" This time Hong Tao finally seized the opportunity, I let you not like to talk, you have to say it if you don't say it, otherwise it depends on how you explain it to your father.

"It looks like a familiar acquaintance from afar, take a closer look...... I don't know. Strange, the inside and outside of this furnace are scattered in a row, but there is a deep meaning? Following the horse along the pedal of the craftsman from the bottom of the furnace to the top of the furnace, Wang Hou became more and more confused.

He is no stranger to iron-making furnaces, not only has he seen but also built, and he was responsible for supervising the construction of ironworks in Xizhou, specifically providing arrows for his father.

Originally, I thought that the refining furnace made by the horse was nothing more than a larger one, and I was not optimistic, because the larger the furnace body, the more difficult it was to increase the furnace temperature, and the strength of the furnace body could not be solved, and it would collapse if it was not good.

But after looking at the internal structure of this iron-making furnace, half of the contempt disappeared immediately. Instinct told him that there must be a mystery in this stove, not a whim of the horse, but he couldn't tell what the mystery was.

In fact, Wang Hou was deceived, there was only one real iron-making furnace, and the remaining two were hot blast furnaces.

They do not make iron, but only collect the blast furnace gas from the top of the blast furnace, which is hot and can continue to burn, and then blows the blast furnace gas through the refractory pipe from the bottom of the blast furnace, which does not require any fuel to raise the furnace temperature by a large margin.

This is the most basic heating method used in the modern blast furnace of the steelmaking plant in later generations, not only to blow hot air but also with pure oxygen and coal powder, and the furnace temperature can be adjusted, as much temperature as it needs, so that the quality and composition of the iron can be artificially intervened.

Hong Tao couldn't make a modern iron-making furnace, and there was no place to find pure oxygen, but this set of theories had been thoroughly pondered by the craftsmen of the Jinhe Empire, and the parts that could be done were restored, such as hot blast stoves and preheating chambers.

In the absence of qualified cast iron pipes, Hong Tao can only use a hot blast stove, and the preheating chamber has to wait.

"Lao Wu, come and tell Lord Wang what these furnace rooms are for." However, it is not easy to explain these theories, Hong Tao doesn't want to speak bitterly in the vernacular again, but his lazy way is also very cunning, not to say that he is too lazy to speak, but to let Wu Er talk about it.

In this way, you can not only save your mouth, but also assess how well the martial arts family has learned, if you can't even remember these basic structures, then you have to consider replacing people.

"Is there wind burning on the fire?" Wu Er should have remembered that he was right, but he still didn't understand it when he heard Wang Hou's ears, especially about the gas. It's unbelievable that the hot air burns, and you can't see or smell it.

"Lord Wang, don't worry, Xiao Lao'er didn't believe it when he first heard it, but the big officials made me speechless when they made a little trick, and I didn't dare to say a word about iron smelting in front of the big officials from now on."

Wu Er's answer made Wang Hou even more surprised, after all, it is also a blacksmith family that has been relied on for several generations, and it is basically impossible to use iron smelting to blind them. So, is the pony really good at making iron?

The truth was soon confirmed, and after a brief ritual was over, the furnace at the bottom of the blast furnace was lit. With the smoke coming out of the top and the color, Wang Hou can roughly judge the temperature in this furnace.

At first, there was nothing unusual, and it was even slower than the heating up of a normal iron-making furnace, but as the four craftsmen stepped on the blower to blow air into the furnace, the color of the smoke quickly faded, and the furnace temperature increased rapidly.

This is not the most surprising, as the temperature of the furnace increases, the temperature inside the hot air chamber also gets higher and higher, and the walls made of blue bricks even appear to be burned through the color, secretly red!

"Father, what the horse said is true, just at this temperature, Da Luo Jinxian will be refined when it reaches the furnace, and it will be difficult to survive the iron and stone."

Wang Shao couldn't stand for a long time after recovering from a serious illness, and was let by Hong Tao to drink tea and rest in Wujin Xing, Wang Hou immediately found his father after seeing the temperature of the furnace and made a detailed report on the observed situation.
