There were tanks in the Northern Song Dynasty

Chapter 86 Cast Iron Pot

The next day, Jiangdian Town.

What Li Chu said yesterday had an effect. There are quite a few people coming to Jiangdian Town today. Everyone is looking forward to watching Li Chu and wanting to see what livelihood issues Li Chu said today.

Gaoxin is also here.

Yesterday was a slap in the face. Gao Xin was also very curious about what Li Chu brought up so carefully. Looking at Li Chu's recent past, he never made any unreasonable remarks. Since he said this, there must be something big, so he came too. have a look.

Li Chulai was the first to arrive at Jiangdian Town with a team of township soldiers early in the morning.

The local residents of Jiangdian Town looked at Li Chu coldly, still hostile and wary.

Li Chu didn't bother with this group of people. He wanted to find someone. He was a blacksmith who lived in an open space next to Jiangdian Town.

There is also a blacksmith in Rufen Town, but the conditions there do not meet Li Chu's requirements. Li Chu needs a boiler that can burn iron into molten iron. It is troublesome to customize this thing, and Li Chu can't operate it. Anyway, during the Northern Song Dynasty , There are also many blacksmiths with boilers.

The horse blacksmith here in Jiangdian Town happens to have a boiler, which is why Li Chu set up his location here.

At the south entrance of Jiangdian Town, there are several soldiers leading the way at the entrance of the town.From the situation in Rufen Town, everyone knew that this was Li Chubing. Gradually, many people came and gathered in the open space next to the blacksmith.

Fortunately, this place is big enough to accommodate a lot of people, let thirty soldiers maintain order, make a human wall, and separate this book by some distance, mainly because the things Li Chu wants to tinker with are too dangerous. When these people rushed in excitedly, they would cause a lot of damage.

On the open space, there is still a large pile of river sand, which was picked up by more than 30 soldiers in baskets when they came from Rufen Town this morning.

On the ground, there are five square boxes made of wood, divided into upper and lower parts, with hollows in the middle. Each box is 50 centimeters high.

And on the other side of the open space, by the side of the house, there is a boiler, and the charcoal fire inside is very hot, and you can feel the scorching temperature inside if you get a little closer.

The blacksmith is loading some scrap iron or small pieces of iron into a crucible, and there is already a crucible burning in the boiler.

Li Chu glanced at the crowd around him, and there were quite a few of them.

Gao Xin, Boss Gao walked to the middle of the field, but Li Chu didn't let the soldiers stop him. At this moment, Gao Xin and Li Chu were chatting with each other, and they were talking nonsense. They tried each other occasionally, but they didn't get any results.

Gao Xin wanted to ask Li Chu what he was doing, but Li Chu only answered four words silently: "Just look at it."

Judging by the people around, the iron in the boiler is probably almost melted.

Li Chu separated a pile of fine sand, poured some water into it, made the sand moist until it could be pasted into a block, and then stopped, and then brought one of the square boxes over.

This box, called a sand mold, has two layers, upper and lower, connected by a hinge. Li Chu opened the upper layer, poured sand into the mold with a shovel, filled the lower part of the mold, and pressed it slightly.

When Li Chu was making this thing, he deliberately placed the mold in the middle so that the surrounding crowd could see it clearly.

"Didn't you say that today is about everyone's livelihood? What is Brother Chu doing?"

"I don't understand, it looks like I'm tinkering with something."

"Sand, Brother Chu brought the sand all the way here, what is it for?"

In the crowd, some people were chatting and discussing in whispers, but they were confused by Li Chu's action. If Li Chu hadn't brought a team of soldiers here today to maintain the continuation, the formation seemed very Seriously, otherwise some people would have left impatiently.

Gao Xin was even more curious. Standing beside Li Chu, he could see more clearly.

Li Chu's actions didn't feel like he was discussing everyone's livelihood, but more like children playing with mud.

Li Chu used his hands to put sand from the middle of the compacted fine sand, and made a pit the size of the outline of an iron pot, and then used a sieve to sieve some washed sand into the pit to adjust the size of the pit. took an iron pot.

This kind of iron pot is the kind of iron pot with integrated handle on the big stove in the rural homes of later generations. It is several circles smaller in size and 35 cm in diameter. It is re-customized from the system.

Li Chu put the iron pot into the pit, then filled it with sand through a sieve and filled it with fine sand. Then he filled the gaps around the iron pot with the washed sand. Finally, he shoveled in the sand and sifted the entire iron pot. The pot was buried.

After the burial, Li Chu stood on the box and stepped on it to compact the sand.

"Why do I feel that everyone has been tricked by Brother Chu? He called him all the way here just to watch him play in the sand."

"I don't think so. Although Xiao Chu used to be a jerk, but recently Xiao Chu has performed very well. He won't make jokes with everyone about such big things. And look at Xiao Chu's serious appearance. It doesn't look like he is playing. ?”

"Uncle Li is right. I think Brother Chu must have a deep meaning in doing this. You might as well wait a little longer. You should be able to know why Brother Chu does this later."

……

After about a while, he gently pushed the sand away, leaking out the iron pot inside, and then took out the sand in the iron pot, tamped the iron pot around it evenly, and then turned the upper cover from the side to cover it.

The upper cover is the same thickness as the lower one, and the middle is also empty.

Li Chu bent a thick wire to make a cross, put it inside the upper cover as the inner structure, and then began to bury wet sand in the upper cover, filling the entire box with sand.

Three soldiers were called to stand on it and step on it together. After touching it, they took a stone hammer and hammered it vigorously to compact the sand and soil again.

In this way, a simple sand model is considered a semi-success.

Open the box up and down, the upper part formed a protruding sand mold upper body, carefully took out the iron pot in the lower half, the lower half was a concave sand mold lower body, Li Chu then moved the lower body A little lime was sprinkled into the mold, and the iron pot was put in and pressed for a while, and then a layer of lime was sprinkled on the protruding mold of the upper body, and a sand mold was completely successful.

"Hey, this thing..."

"Although I can't understand it, the thing that Brother Chu made looks very beautiful."

"I saw a little way, this thing feels like the brick factory, it seems to be a mold."

"Mold? What's a mold for?"

Gao Xin was also puzzled. At first, at this moment, he would no longer foolishly think that Li Chu was really playing with sand.

At this time, the iron in the boiler also melted into molten iron after passing through a high temperature of [-] degrees.

After removing the impurities on the molten iron, pour the molten iron into the concave of the lower body of the sand mold, and then close the sand mold.

Bursts of white smoke came out of the box, arousing the surprise of the onlookers.

After four or five minutes, Li Chu opened the sand mold up and down.

The molten iron has cooled and solidified, and the upper body of the sand mold has lost its agglomeration at such a high temperature and has scattered into fine sand. Li Chu took out the fine sand, and the molten iron solidified under the squeeze of the mold. The shape is an iron pot.

When Li Chu lifted up the iron pot...

Gao Xin was stunned.

The crowd of people watching were also stunned.
