I am not an ant thief in the Three Kingdoms

Chapter 49 Chapter 49

The reason why the old man Niu welcomed Xu Wei was that Xu Wei could improve the quality of iron smelting with random suggestions. Before joining Xu Wei, he was just an ordinary blacksmith, but with Xu Wei's suggestions, he had already learned how to make hundreds of smelting irons. The sword is gone, just a stacking technique and a blower technique instantly made the old man Niu a famous sword forging craftsman.

And now Xu Wei is teaching Old Man Niu the technology of blast furnace ironmaking.

In this era, charcoal is generally used for ironmaking, so that high-quality swords can be made.Although Bingzhou has a lot of coal, people in this era also thought of using coal to make iron, but China's coal mines and iron ore have a lot of sulfur, and if the iron is added with sulfur, it will be very brittle, so the refined iron is basically scrap iron, so everyone I would rather use expensive charcoal to smelt iron than coal.

People in this era obviously don't know the steps of desulfurization. Of course, there may be a few famous sword masters who know it, but they have kept this method as a family treasure and strictly guarded against it. It has not been popularized, and it was finally lost in the war.

But desulfurization is no secret to Xu Wei.

Although he was a scumbag when he took chemistry class, he read thousands of novels and learned a lot of useless knowledge. Among them, adding a little limestone to iron smelting can improve the quality of steel.

Don't ask me about chemistry!

Reaction equation don't ask me!

My chemistry teacher died early!
Well, the chemistry teacher is not dead. The real reason is that Xu Wei, a scumbag, has basically forgotten his high school chemistry knowledge, but he knows that as long as it is a farming novel, there must be limestone in the iron making novel.

So he asked the old man Niu to try it, and he really used coal to smelt 100 catties of molten iron. The quality was not bad. The old man Niu was so shocked that he wanted to worship Xu Wei as his teacher.

In this era, Xu Wei didn't even have access to the Internet, so he became interested in this phenomenon. After thinking about it for a few days with his meager chemical knowledge, he felt that it might be due to the neutralization of acid and alkali, which instead increased the quality of iron.

The ironmaking technology in the Eastern Han Dynasty was not very good, otherwise Xu Wei would not have taught a master swordsman by improving the blower a little.

Although Xu Wei had never practiced iron smelting, he saw that the old man Niu and the others could not even get molten iron out of iron for a long time, so he knew that it was because the temperature of the charcoal was not high enough to smelt molten iron.

And to increase the temperature of iron-making, Xu Wei understands that using coke to smelt iron is enough. Build a kiln, put coal in it and ignite it, let the coal burn to normal and then close the kiln, leaving coke.

Old man Niu used the coke he got from Xu Wei to smelt iron. He felt the temperature and excitedly said: "This temperature is much higher than charcoal, and it should be able to smelt high-grade steel!"

Soon the molten iron was refined and poured into the mold. After cooling, several plowshares appeared.

The old man Niu looked at the plowshare and said excitedly: "The quality of this iron is very high, and it can be used after a little polishing!"

With several pointers from Xu Wei, the old man Niu has already regarded Xu Wei as the god of iron smelting, and he can be said to obey what he says.

And Xu Wei also saw all the knowledge about ironmaking from the farming novels, the old man Niu, who is a master.What kind of blast furnace, what uses hot air to increase the speed of ironmaking, what kind of hydraulic hammer, etc.Xu Wei didn't like this kind of iron output of one hundred and dozens of catties each time.

The excited old man Niu found his son and asked him to write down what Xu Wei said in a note. Keep the heirloom.

Xu Wei continued calmly: "We are going to build a new blast furnace, and in the future we will have to pump 1 catties of iron at a time to be enough for us!"

Hearing this number, the old man was so surprised that he could not close his mouth from ear to ear, but thinking of Xu Wei's magical method, he still followed Xu Wei's instructions to build the blast furnace.

But soon the old man Niu found Xu Wei again and said: "Captain, the temperature of the coke is too high, the furnace can't handle it, it's all burned."

Xu Wei was startled and said, "No one was injured, right?"

The old man Niu said: "No, after the old man found out about this situation, he asked people to leave the stove."

Xu Wei said: "It's because bricks are not good. You need to use refractory bricks. You can go to Uncle Wang and tell him to add some graphite to the bricks used to build blast furnaces in the future."

Xu Wei remembers that aluminum is added to refractory bricks, and there are also graphite crucibles. Aluminum Xu Wei can't get it out, but graphite is very common. Adding some should be able to make refractory bricks.

At the same time, he also said to the old man Niu: "Old man, you can also add other minerals and try it, maybe you can make more powerful refractory bricks. This ironmaking requires high temperature. If the bricks are not good, they can't withstand the heat. Good job!"

The old man Niu nodded approvingly!

At the same time, he said to the old man Niu: "We are not afraid of problems, and we will improve the problems when they occur."

But refractory bricks are not a panacea, they just melt slower, so the old man Niu found Xu Wei again.

"The old man has to think and solve the problem by himself. I have given you all the ironmaking knowledge I know." Xu Wei couldn't tell whether to laugh or cry, and he just had to use three tricks.

But the old man Niu said as if he should: "Captain, you are the master of iron smelting. There is no one in the world who knows more about iron smelting than you. Instead of us thinking about it for a long time, dragging down the progress of iron smelting can't solve the problem, why not?" Why don't you come here and ask for your help, the captain needs to know that everyone in the suburbs of Mayi is opening up wasteland with wooden plows, so you can bear to watch everyone use wooden plows to open up wasteland?"

At the same time as iron smelting, land reclamation outside Mayi also began. Xu Wei knew the shortcomings of big pots of rice, so he directly divided the million acres of wasteland into 14 pieces. Each district has a piece of wasteland for 10 people. Divide it into 10 small blocks, and divide each ten small blocks into ten pieces of wasteland less than [-] mu, which will be reclaimed by a team of [-] people, so that the amount of land reclamation is fixed, and the group of ten people are all acquaintances, so Hunzi is embarrassed to look at other people people work hard.

At the same time, Xu Wei divided the cattle and horses into groups, but the lack of agricultural tools was too large, and everyone had to use simple agricultural tools such as wooden plows, hoes, and shovels to open up wasteland. Such efficiency can be imagined.

Xu Wei said helplessly: "Okay, I'll help you think about it!"

Xu Wei stayed in the steel factory for a few more days, and the only way he could think of was to make hollow refractory bricks, so that the heat insulation effect would be better. Use water to cool down!"

This is already a trick that Xu Wei can think of, of course he doesn't know if it will work.

The new refractory bricks can finally resist the overheating of coke. The blast furnace that Xu Wei wanted was finally built by the old man Niu. Although it is only 2 people tall, it is completely a blast furnace in Xu Wei, which is probably at the level of the Republic of China period.
But in the eyes of Old Man Niu, this is a major historical process, and Old Man Niu specially invited all the high-level executives like Xu Wei to the steel plant.

When the molten iron flows to the grinding tool.The old man Niu proudly said: "This blast furnace smelts more than 1 catties of iron every day, and can produce thousands of plowshares a day. As long as the old man is given a month, the wooden farm tools in Mayi will never appear again."

But Old Man Wang and the others looked at the blast furnace as if they were looking at an alien spaceship, it was Zenith Star technology.

Xu Wei didn't even know that under his transformation, ironmaking technology had leaped by a thousand years, and this small blast furnace had reached the technological level of the 19th century.
