Zhang Yuan had already seen Uncle Li, the steward, outside the gate of the workshop, and when he went in to say hello, he found that Uncle Li had disappeared.

This is still hating me, and my temperament is not good when I'm old, hum, short-lived.

The largest consumption of fuel in the smelting workshop is not iron ore, but in order to have enough fuel, behind the workshop is a green forest that stretches to the mountains in the distance.

There was no need to worry about the materials used to build the house, Zhang Yuan led a hundred servants from the workshop and went out through the back door to the front of this green bar forest.

Zhang Yuan couldn't change the fate of these servants, but he was able to tell them their fate, even if some people already knew what the outcome would be after knowing that the destination was a smelting workshop.

"Ladies and gentlemen, most of you may already know what you have to do when you come to the workshop, but you are brought by me Zhang Yuan, and I will be responsible for you.

You can cut down the green bar trees here these days to build a house, this is where you will live in the future, and I will give you half a month.

As long as you don't build a palace here in this half month, I can accept the rest, but once this half month is over, you will only have hard work left every day.

So that you can rest better every night, this is the only thing Zhang Yuan can do for you.

I won't say anything else, there must be a steward among you, let him take you to build your own residence, and I will come again in half a month. ”

When it came to building the palace, the worries on the faces of these people began to loosen.

After saying these words briefly, Zhang Yuan left here, there are not many other smelting workshops, these tools must be enough, Zhang Yuan can't draw a drawing and let them follow it.

When he arrived at the place where the blacksmiths were working, Zhang Yuan saw Uncle Li, the steward, who was leading more than fifty blacksmiths around a workbench, obviously waiting for Zhang Yuan to arrive.

"Uncle Li, boy, I'm here."

No matter what contradictions there are between the two, Zhang Yuan's low posture as soon as he comes up still makes Uncle Li very comfortable.

"Zhang Gongzi, according to the instructions of the head of the family, I have gathered all the blacksmiths in the workshop here, and asked Gongzi to teach them new skills."

Seeing a pile of wrought iron plates and pig iron plates on the side, Zhang Yuan smiled heartily at Uncle Li.

He finally understood why Zhuo Wenjun respected this middle-aged man so much, even if the other party was unhappy with him, he could still let go of everything in the face of major rights and wrongs.

"Boy, thank you Uncle Li."

After thanking him, Zhang Yuan walked over and selected the thinnest piece of wrought iron plate, and then picked a piece of iron plate with a thickness and size suitable for making an iron pot.

"Ladies and gentlemen, we only need wrought iron to build the iron pot, because the toughness of wrought iron will be better.

The thickness of this piece is more suitable for making an iron pot.

The kid is just demonstrating it for you today, so I'll use this thinner demo. ”

Saying that he couldn't teach it, Zhang Yuan put the wrought iron plate on the stove and burned it red, then picked up the blacksmith's hammer and began to beat it on the anvil.

It wasn't until Zhang Yuan's shadow coincided with his whole person that this display was completed.

The process is not very difficult, the blacksmiths only need to create a rough embryo, and then the servants brought by Zhang Yuan should polish and remove rust.

Zhuo Wangsun, the wooden handler, invited a special carpenter to carve, in order to engrave the four words of Linqiong Zhuo on it.

"Do you have any questions, masters? If not, let's disperse, and then you'll all have to stop other work and start building iron pots. ”

The people present are all masters who have been immersed in the construction of iron tools for more than ten years, and after watching it all morning, they naturally feel that they will definitely be able to build it.

No one asked, which was nice.

Zhang Yuan let out a sigh, as for the mistakes they made in the construction process later, and the wrought iron lost was not reimbursed by Zhang Yuan, he naturally wouldn't worry about Zhuo Wangsun.

Teaching these blacksmiths the craft of making iron pots is only one of Zhang Yuan's purposes, and he has to complete the things he forgot last time when he comes this time.

Experimental steel filling techniques.

Uncle Li, the steward, had long since disappeared, and Zhang Yuan took the thickest wrought iron plate from his platform and returned to the high-temperature furnace where iron ore was smelted.

At present, Zhang Yuan's identity can no longer be compared with before, he does some weird behavior, and no one will complain to Uncle Li.

Even if someone goes to complain, will Uncle Li whip him? Joke.

The mold containing the liquid pig iron was replaced with this wrought iron plate, and the servants on the side opened the yellow mud plug that closed the outlet of the molten iron, and a stream of dark red pig iron flowed down and poured it on the wrought iron plate.

Zhang Yuan used the wooden stick in his hand to push the wrought iron plate, trying to pour the molten iron evenly on the wrought iron plate, and when the molten pig iron had completely covered the wrought iron plate, Zhang Yuan waved his hand to block the exit again.

Next, he could only wait for this iron plate to cool down, and as the iron plate gradually cooled down, Zhang Yuan suddenly realized something.

It seems that he doesn't know how to tell the difference between steel and iron, and he only knows that the carbon ratio is different, but he can't observe it with the naked eye.

......

This is a big problem for Zhang Yuan, but fortunately, there are more than fifty blacksmiths in this complex.

"Master, do you know how to distinguish a piece of steel?"

The master asked by Zhang Yuan was drawing a circle on a wrought iron plate, and when he heard someone ask him, he looked up and found that it was Zhang Yuan, and immediately replied respectfully.

"Zhang Gongzi, what do you want to know?"

The master's attention was all on the wrought iron plate just now, and he didn't hear Zhang Yuan's question clearly.

"I want to know how you usually tell the difference between steel and cast iron wrought iron."

Although there is no steel frying method in Linqiong, most of these blacksmith masters have mastered the skills of steelmaking.

"If a piece of material is silvery-white with a broken edge, it is steel.

The villain has broken cast iron and wrought iron, childe, you can take a look. ”

Zhang Yuan took the two pieces of iron handed to him by the blacksmith and began to observe, it was indeed as he said, there were colors.

Fortunately, the method of distinguishing steel is not very difficult, and you can distinguish it by taking these two pieces of iron and comparing them with your own piece of iron.

"Thank you, master."

Taking out a good piece of silver from his arms, Zhang Yuan handed it to the blacksmith, who just nodded gratefully and looked around.

He was probably afraid that others would find out about this property, although the status of these blacksmiths was slightly higher than that of those handymen outside, they were actually still slaves of the Zhuo family, even if they did more, they still didn't have a penny.

Zhang Yuan dragged his piece of iron, which he didn't know what it had become now, back to the previous workbench, called a few people to help clamp the iron plate in the middle with two anvils, and began to hammer it down with all his strength, when the edge of the iron plate was only bent instead of being broken, Zhang Yuan could only move the position of the iron plate and keep knocking it inside.

"Childe, do you want to see the color of the fracture?"

The blacksmith who had been pressing the anvil hard was numb from the shock, and asked with a not very good-looking face.

"That's right."

Zhang Yuan nodded.

"This piece of yours should be wrought iron, I'll help you see it with a saw, and then it will be easier to smash it. Or if you look at the color of the saw mark, it's actually the same as the fracture. ”
