When we arrived here, there were also several people working. Because of gunpowder, building roads did not require much labor to be dug.

Therefore, the personnel are relatively scattered, and several construction sites are opened at the same time, such as this place where the ground furnace is built.

The ground furnace is a place for iron smelting, because iron smelting requires a very high temperature. Only by building a furnace underground can the heat not be dissipated.

Wang Kang went directly to a shed, which was the temporary construction command center. At this moment, there were already many people surrounded and a few strange faces.

Seeing Wang Kang approaching, Nie Zhongxing came up and said hurriedly: "Young Master Kang, the craftsman has arrived. It was brought by Deacon Xu of your family in person."

"Xu Changlin? He is here too!" Wang Kang said with a smile.

"But, those craftsmen made suggestions on the floor furnace we built," Nie Zhongxing said again.

"Oh? What's wrong?"

"You'd better go over and see it yourself!"

Wang Kang followed Nie Zhongxing and several people surrounded him. Xu Changlin said: "The craftsmen he was looking for by the Count has arrived. Three of them are from the Metallurgical Bureau. I will introduce them to you."

"This is Li Zheng,"

Xu Changlin pointed to a slightly thin middle-aged man and introduced: "Master Li is the iron smelting master of the Metallurgical Bureau, and the ground furnaces of the Metallurgical Bureau are all under the supervision of Master Li."

"Master Li has come here and is wrong, please forgive me," Wang Kang said politely.

If you can come from Kyoto, no matter who you are ordered, you should treat it yourself.

However, Master Li just nodded lightly and did not respond.

Seeing that the scene was a little awkward, Xu Changlin pointed to another person and introduced: "This is Master Xi and a famous cast iron craftsman. He has improved the purity of iron embryo..."

"This name is Wang Fuchen, who is also a master blacksmith."

Xu Changlin pointed to the others around him and said, "They are all craftsmen who come with them, and they are all good at the Metallurgical Bureau."

Seeing such a lineup, Wang Kang knew that his father must have invested a lot of money, and he didn't know how to invite so many people.

This is also the division of labor between father and son. Wang Dingchang provides resources in the front, while he engages in construction in the rear.

After seeing the few people one by one, Wang Kang smiled and said, "Thank you for coming here to help, it's like a tiger with wings!"

However, his experience did not receive a good response. The thin middle-aged man, who is famous for Li Zheng, picked up a few drawings and asked coldly: "It is said that the earthen paper in the ground was painted by you?"

"Yes, what's wrong?"

Wang Kang asked in confusion, and he was also a little confused. Why did these people have this attitude towards him?

"I'm going to do it all in a daze!"

“It’s ridiculous,”

"A rich young master is still making mistakes."

Several people agreed, which made Wang Kang's face darker...

When we met for the first time, we criticized him without any discretion. Even if you are from the Metallurgical Bureau, you can't do this!

Seeing this scene, the people around him were all giving gifts to each other. Nie Zhongxing had bad intentions and was convinced by Wang Kang.

These people are clearly here to find fault.

When Xu Changlin saw Wang Kangyin angry, he hurriedly whispered: "Young Master Kang, these are all counts who spend their energy to invite them. If you have any questions, you will be tolerant..."

"Tolerance?"

Wang Kang sneered, and he could only criticize things without seeing it. He asked lightly: "I don't know how many of you, why do you say this?"

Li Zheng expanded the drawings and pointed at it and said, "The ground furnace is used for iron smelting, so it is especially necessary to be cautious in the construction. It is not possible to have a single point in the difference."

"And the drawings you have drawn, the iron extending from the floor furnace extends to the road, is connected to another floor furnace, what are you going to do?"

Li Zheng said coldly: "It is a taboo to connect two floor furnaces. The floor furnace temperature is extremely high, and the furnace and jade often explode because it cannot withstand the high temperature!"

"Two floor furnaces are close, which is extremely dangerous in itself..."

"Seeing your drawing mark, the iron dissolved from the first floor furnace flows to the second iron furnace and re-solution, which is simply a waste of time."

"And this..." The craftsman named Wang Fuchen also spoke: "You have divided multiple outlets from the molten iron dissolved from the second floor furnace..."

“This is totally random construction!”

After listening patiently, Wang Kang understood that it was because they saw their own drawings that they said so.

He shook his head, and what he planned was not just smelting iron, but steelmaking.

The first floor furnace, the dissolved molten iron will be heated and dissolved by the second floor furnace, and the steel can be produced and then flowed into the pre-installed mold.

After cooling, it becomes steel directly.

They certainly don't understand this.

Wang Kang thought for a while and said, "I will explain the first question to you first. As we all know, iron smelting requires extremely high temperatures, and ordinary floor furnaces are made of bricks."

"But due to the high temperature in the furnace, the bricks cannot bear it for a long time, brick cracks and even furnace frying will occur, which is also a problem you are worried about."

After hearing this, the few people nodded. When they looked at Wang Kang, their eyes were different because they were very professional.

Can a rich young master understand this?

Wang Kang ignored it and continued: "The essential reason for this is that the bricks are not refractory enough, and I have found a better refractory brick!"

"Impossible!" Li Zheng shouted directly.

Master Xi also shook his head and said, "The refractory bricks have been researching and have tried many of them. It is impossible to have better refractory bricks."

"You don't know, but it doesn't mean there isn't!" Wang Kang said directly.

"My mouth, my Metallurgical Bureau is engaged in this matter, don't we know?"

Wang Kang didn't say anything and ordered Nie Zhongxing, "Take a piece of brick that I asked you to burn."

After a while, Nie Zhongxing took a square red brick, Wang Kang pointed at him and said, "This is the refractory brick I made."

"Ha ha!"

"That's it?"

"What's the difference between this and ordinary bricks? Are you kidding?" several people said with a smile.

But Wang Kang said coldly: "You can be ignorant, but you can't be fearless!"

"This brick is made of high alumina bauxite, clay and pulp. What is high alumina bauxite? I believe you don't know."

Wang Kang continued: "Then I will popularize it for you. High-alumina bauxite is the abbreviation of high-alumina material. Its essence is also an ore and a sedimentary deposit."

"This kind of ore is available in Xinfeng County. Its clinker can be used to make high-aluminum bricks, that is, refractory bricks!"

Wang Kang's words made Li Zheng and others stunned. Many of them were heard for the first time.

Wang Kang didn't explain much. When he was preparing to smelter iron, he had already thought about all possible problems.

For example, the bricks needed to build a floor furnace are a problem. Conventional bricks obviously cannot withstand high temperatures, so he fired fire refractory bricks.

"This is purely your words,"

Li Zheng snorted coldly and said, his expression was not very good either, because he basically didn't understand what Wang Kang said just now.

"Whether it's just a word, it will be clear after the trial," Wang Kang did not allow any advice.

"This question is revealed for the time being," Master Xi said at this time, "Then let me ask you, why do the dissolved molten iron be refined in the furnace again?"

Wang Kang said directly: "Because I want to make something harder than iron...steel!"
