Three days later, Liu Yuanshan took the red deed in his hand and smiled slightly, no matter what, the Zhao family didn't do anything in the end, and the land he bought was in hand. Pen, fun, pavilion www. biquge。 info

As for the price, it will be calculated according to the price agreed by everyone before, according to four taels of silver per acre of land.

Now that you have land, you have to prepare for the cultivation of the land, after all, after the New Year, spring is not far away, and the day of cultivation is coming.

Every morning is still a training camp, and in the afternoon, there is less and less time to go hunting in the back mountains, and a lot of time is spent on composting. All the subordinates, even Sister-in-law Fan and Xiaoyu Xiaoqing, went out in person to collect sundries, dung, grass stalks and other things in the corners of the village, and piled them together to ferment and dung.

When he was in the town of the mountain, he also went to the town once and bought two cows and a cart.

As for some other miscellaneous things such as farm tools, it is much more convenient to buy them directly as finished products.

A few days later, one returned with good news, and this time he brought three thousand pounds of pig iron to the mountain. According to the market price, the price of each catty of pig iron is almost ten yuan, and thirty taels of silver and three thousand catties of pig iron are just right.

Of course, he couldn't bring all the pig iron with him at one time, but most of it was left at the dock in Gushan Town, and he only used a small part of a few hundred catties to transport it over.

Liu Yuanshan was very happy, and ordered people to go down the mountain and rely on manpower to carry hundreds of catties of pig iron up the mountain, and it would not take much effort if there were many people. As for the rest of the steel, it would be enough to arrange a few more people to make a few more trips.

"This is pig iron!" In this life, including in the previous life, Liu Yuanshan has never seen much pig iron, and he rubbed a piece in his hand for a while, feeling that the weight of iron is about the same as the steel in his previous life, but the surface is rough and scraping, guessing that it should be due to the high carbon content. This iron is also generally susceptible to corrosion and rust.

"Yes, this is pig iron!" One replied excitedly.

Pig iron is the product of the initial removal of impurities, and although the carbon content is only between 3% and 6%, it is still too high compared to wrought iron and steel.

If it's iron ore, it should be cheaper!

Liu Yuanshan thought in his heart, his eyes fell on Hong Zongwei, a blacksmith who went out with him, and asked, "Buying so much pig iron at one time, didn't others ask?" ”

"Nope!" Hong Zongwei took a sip of water and replied: "Young master, you don't know, this pig iron is all produced locally, we went directly to this mine, there are more people selling iron there, where is anyone asking!" ”

"All to buy pig iron?" Liu Yuanshan asked again.

"No, no one buys pig iron, most of them used to buy iron and stone, iron and stone are cheap, one pound of pig iron can buy five pounds of iron and stone!" Hong Zongwei is a blacksmith, and he is more familiar with the set of iron, and continued: "This iron and stone is nothing, after the blacksmith buys it back, it is pig iron with a little tempering and beating, and half of it can get two catties of pig iron for three catties of iron and stone." ”

According to Hong Zongwei, the iron content of this iron ore is about 60 or 70 percent.

"Then why don't you buy iron ore?" Liu Yuanshan felt that he had lost a lot of money by buying pig iron.

"Because, because of ......" Hong Zongwei was stunned for a moment, cold sweat couldn't help but flow down his forehead, and he whispered: "Because the young master arranged for us to buy pig iron!" ”

"Hmm!" Liu Yuanshan just complained and didn't really want to punish his subordinates, shook his head and said: "It's not your fault, if you go again next time, just buy iron ore directly, no need to buy pig iron." ”

The manufacturing process of pig iron is simple, and he can do it in minutes, isn't it smelting!

"Okay, okay, pig iron is pig iron, now you are ready, let's make steel!"

The steelmaking furnaces have been ready for a long time, and after a month of sitting, they have long since dried.

The furnace is based on the technology of the Republic of China in the fifties and sixties when the whole people made steel, on the whole, the furnace is divided into two layers, the upper layer occupies most of the space, which can put charcoal and ore at the same time, and when making steel, the air is sent into the main chamber to support combustion with a blower, and the iron ore can be melted at high temperature, and the carbon element in the molten iron is reduced through oxidation, and the legendary steel can be obtained.

As for the cavern below, it has no special function, but the fire is used as an auxiliary to the main chamber above, which has a kind of thermal insulation effect, just like the hot air must be blown when blowing air into the main chamber, all to maintain the temperature and melt the iron ore.

The process of steelmaking, which is the process of decarburization, desulfurization and dephosphorization, is easy to say, but it is difficult to operate. Predecessors or descendants have spent hundreds of years exploring the process of steelmaking.

Liu Yuanshan stood on the shoulders of giants, and when building the entire main room, he not only pasted a layer of ceramic refractory materials inside the main room, but also put a layer of block limestone at the bottom of the most critical main room, in an attempt to use the alkaline neutralization effect to remove the sulfur and phosphorus in the pig iron.

As for decarbonization, it is more difficult, coke is used in later generations, Liu Yuanshan has no coal in his hands, naturally there is no coke, can only use charcoal instead, although the efficiency of decarbonization is a little lower, it is not impossible.

The completion of this steelmaking furnace took a lot of Liu Yuanshan's hard work, of course, although this furnace is an old routine of the local law, it is not much stronger than the national local steelmaking furnace in the Republic era.

So far, there is one more problem that has not been solved: blower!

If in the modern society of later generations, a small blower could be bought for a few hundred dollars, and even in England in the 17th century, a steam engine could be used to drive the blower to deliver oxygen to the main steelmaking room. But in the Ming Dynasty, this kind of condition is small, and it is much more difficult to find a stable blower equipment.

No, it should be said that it is not possible at all!

In ancient times, there was a blower, called Lulang, which was almost to make a bulging thing and then squeeze the air supply, but you don't have to think about it to know that the effect must be terrible.

Liu Yuanshan didn't think about using a bellows, he wanted to use bellows. No way, although the bellows are unstable, the air supply is guaranteed, at least there should be no problem in raising the temperature inside the furnace to the point that the iron melts.

So, people made a huge bellows according to the idea.

The bellows is wooden, the piston in the middle is a mixed structure of chicken feathers and wooden boards, the confidentiality is very good, the piston and the bellows are also relatively tight, one person can not pull, to use four or five people at the same time can be driven, the air volume is naturally possible.

At the moment, everything is ready, even the east wind is ready, naturally it is foolproof, Liu Yuanshan looked at the nearly two-meter-high earthen furnace, nodded and said: "Let's start, steelmaking!" ”
