Chapter 260: Iron Smelting

After talking about the particle gunpowder, then this firearm Yunxi has no suggestions, and he is not a graduate of explosives and other related majors, and all he can think of in the past six years is these things.

After talking about firearms, let's talk about blast furnace ironmaking. Pen % fun % Pavilion www.biquge.info

Yun Xi asked the leader of the craftsmen in charge of firearms named Wang Baoquan to step down, and asked Tingshan to call the leader of the iron-making craftsmen over.

Originally, there were no craftsmen for iron-making, and they were not responsible for iron-making, so they all needed to be allocated from the Yu Heng Division under the Ministry of Industry according to the amount used, and then the blacksmiths under the internal officials and supervisors made all kinds of utensils.

But last month, Yunxi ordered the internal officials to prepare some craftsmen with experience in ironmaking. This can make the eunuch Ting Shan of the inner official eunuch anxious, he doesn't know how many times he tossed before he succeeded in getting more than a dozen more experienced craftsmen, so that Yunxi today has someone to teach.

Yes, teach. Although Yun Xi has not personally trained iron, nor has he entered the ironmaking workshop, he also knows a lot about blast furnace ironmaking, and has taught himself the process of ironmaking, and has also used various 'scrap iron' from state-owned steel plants to make all kinds of things.

The blast furnace body is divided into five parts: throat, body, waist, belly and cylinder. During production, iron ore, coke, and slag agent are loaded from the top of the furnace, and preheated air is blown from the tuyere located at the lower part of the furnace along the furnace perimeter. The carbon in the coke at high temperature is combined with the carbon monoxide produced by the combustion of oxygen in the air, and the oxygen, sulfur and phosphorus in the iron ore are removed during the rising process in the furnace to obtain iron. The molten iron is released from the iron mouth. Unreduced impurities in iron ore combine with fluxes such as limestone to form slag, which is discharged from the slag port. The gas produced is discharged from the top of the furnace and used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers, etc. after dust removal. The main product of blast furnace smelting is pig iron, as well as by-products blast furnace slag and blast furnace gas.

The technical and economic indicators of blast furnace ironmaking are good, the process is simple, the production capacity is large, the labor production efficiency is high, and the energy consumption is low.

However, in terms of the level of craftsmanship in the early years of the Ming Dynasty, it was still slightly difficult. At this time, it is difficult to say whether the refractory bricks, fillers, mud, etc. can meet the standards for building blast furnaces, and the slag agent is afraid that the efficiency of limestone alone will be lower; And without a steam engine, it is also a question of whether the power of the blower can send enough air. The most important thing is the temperature, at this time the fuel level can not provide the high temperature sustainably.

Yun Xi explained the model and workflow of the entire blast furnace, as well as the various raw materials used and the requirements of the raw materials, to the head of the craftsman who led the ironmaking.

Suddenly, the head craftsman named Deng Zehong forgot Yun Xi's identity and said in surprise: "Although I have definitely not used this method to smelt iron, I can also feel that you can also smelt iron with this method." ”

Tingshan on the side was also stunned. Since he is the chief eunuch of the internal official prison, of course, he also has some understanding of the skills of craftsmen. And last month, Yun Xi named the internal officials and supervisors to prepare skilled craftsmen in iron smelting, and Tingshan also learned about the process of iron smelting, so he was suddenly shocked by Yun Xi's idea.

Of course, he was not a skilled craftsman and could not feel whether this method could make iron, but he could feel that it was a complete ironmaking process, and an ironmaking process that he had not heard of.

If you want to say that this is what Yunxi 'looks like from a certain book', Tingshan must not believe it. After becoming a young eunuch, he began to study on his own, knowing that because gunpowder was a major matter of the country, some people might write the ratio of gunpowder in a book, but there was no book about how to smelt iron. So this must have been all Yunxi's own idea.

Tingshan is not a civil official, and he has no obligation to advise the emperor not to 'do his job', so he only needs to be shocked that Yunxi, as an emperor whose main business is to intrigue with ministers, is so good at studying ironmaking.

But Ting Shan was still sensible when he was shocked, and immediately reacted after hearing Deng Zehong's words, and scolded: "Don't be rude!" ”

Deng Zehong was also immediately awakened, knelt on the ground and said, "Please forgive Your Highness." ”

Yun Xi said: "You are a first-time offender, and you are not to blame. ”

Yun Xi will not blame him, this is Yun Xi's respect for scientific and technological workers.

But Deng Zehong himself was obviously still very panicked and scared, and stood aside resignedly.

Yun Xi continued: "Such a blast furnace is naturally not suitable for building in the capital, of course, you have to choose a place outside the capital." ”

"I heard that there is an iron ore in this Meishan area?"

Tingshan continued: "Yes, Your Highness, the government-run iron mine in the capital is in Meishan, and most of the craftsmen who make iron under the Ministry of Industry are also in Meishan. ”

Yun Xi said: "The blast furnace that the officials and supervisors tried to build was also built in Meishan. Tingshan, this matter is more important, you will be responsible. ”

"There are a lot of internal officials and supervisors, and it is estimated that there is no shortage of manpower; It's just that there are not enough people, so people from the Ministry of Labor are recruited. But the money is certainly not enough. If you are short of money, you will go to Wang Gong to ensure that the money and food are sufficient. ”

Tingshan is both happy and worried, but for him who is only in his thirties, he is still a little happier. He bowed down and said, "The slave will definitely not disobey His Highness's orders!" ”

Yun Xi said, "It doesn't have to be this way. Blast furnace ironmaking is a new method, which has never been tested before, and it is estimated that the first blast furnace must have many problems, and it is nothing if it cannot smelt iron. Don't build as many blast furnaces as you want at first, build them one at a time, and then build more when there are no more problems. ”

After simmering for a while, Yun Xi continued: "When the first intact blast furnace is built, I want to go and see it." ”

At this time, it was not a proper business for an emperor to study how to make iron, but it was normal to care about ironmaking. After all, what kind of weapon of a military commander or hoe of a farmer does not use iron? The civil servants will not object.

Yun Xi said again: "Feng Mo, you are here to be the deputy of the iron-making matter, and you are stationed in Meishan. "Let a person who is too overseeing things outside the palace, Yun Xi always feels weird, and decides to choose a normal person to actually deal with it.

Feng Mo bowed and said, "Yes, Your Highness." ”

Yun Xi gave a few more words, turned around and returned to the Qianqing Palace.

Ting Shan, Lu Chengfeng, Feng Mo and Deng Zehong knelt to send Yun Xi back. It wasn't until Yun Xi was basically invisible that Ting Shan stood up and said to Feng Mo and Deng Zehong: "I will immediately send someone to Meishan to select a site, and you should also hurry up and prepare, and you must build the first blast furnace as soon as possible!" ”
