Chapter 2481: Iron and steel plant (2)

　　 The success of the cement plant has greatly increased Lin Ze's confidence in the plant.
　　 To build fortifications, build reservoirs, bridges, it is not enough to have cement alone, and how to do without reinforcement, but where is there an iron plant in Huangsha Town, let alone a steel plant.
　　 Although Huangsha Town is one of the later bases of the Baixiang Corps, the iron and steel required for production here are all purchased from Linsha City.
　　The iron and steel industry is the most profitable, and it is also a key point that the royal family attaches the most importance to. Therefore, it is not easy to build iron plants in some places, and all steel plants are controlled by some powerful figures.
　　Lin Ze did not have this qualification if he used to be, but now Lin Ze is different. He can actually say that he actually controls the entire sandbar. Therefore, he wanted to build a steel plant.
　　Even if the royal family knew it, they would not care.
　　 Given a small steel plant, for the royal family of Chu Kingdom, how could they care about it.
However, after a few years passed, the Chu royal family was dumbfounded, because the output and quality of the steel plant built by Lin Ze far exceeded their expectations, and even the output of a steel plant alone could be directly milled. The output of the iron factory controlled by the entire royal family was equalized, and there were three Linze hands at that time.
　　 It was just that it was too late for the royal family to regret it, because at that time, Lin Ze's strength was no longer able to resist the royal family.
　　 There is no iron ore in Huangsha Town, but there are several small iron ores in Mozhen.
Of course, this is just the opinion of others. Lin Ze personally inspected it. In fact, the so-called small iron mines in Mozhen, the actual output is still very impressive, but the current detection methods are too backward, so Will detect errors.
　　Before Lin Ze didn't have this qualification to get involved in these'small iron mines', but now all the towns in Mo are all Lin Ze, so the iron mines here are of course also Lin Ze.
Now there are only three miniature ironworks in Mozhen. The technology is extremely backward. In fact, it is actually a rural iron-making shop. The only difference is that the iron-making shop is slightly larger, but the iron produced is The quality is really'moving'.
　　Some irons, Lin Ze can be broken directly with a light plate, the difference in quality can be seen.
　　 Even iron is of such quality, so the steel behind it will not be said.
　　Don’t say it was made by chance. Until now, none of the small blacksmith shops here has seen a piece of steel.
　　Thinking of wanting to develop in the future, steel may be the most important material, plus the foundation is already there, so soon Lin Ze decided to take advantage of his own time to supervise the work and build his own steel plant as soon as possible!
There are just a few iron mines in Mozhen, and they are still open-pit iron mines. There is no shortage of manpower. Now Huangsha Town is not short of this, and there is no problem with technology. Lin Ze’s plane is full of stone soil in the world. French steelmaking technology.
　　 As for other substances, limestone, coal and the like, there are now iron ore raw materials that want to make iron, and the rest is to start building a steel plant.
　　The most important raw materials for steelmaking are iron ore, that is, coke and limestone. These two are now more convenient for refining after they have a cement plant.
In fact, there are several iron smelting factories in Linsha City, but there are small furnaces with shaft furnace structure, similar to the earthen kiln. The output and quality are not high. For Lin Ze, for Lin Ze, there is really no need to learn from it.
　　 This time Lin Ze is still preparing to use the local method of iron and steel smelting in that era.
　　 In that miraculous era, a few days of effort could build a steel plant, and every area was built, and the ironmaking process was also publicized.
Now the situation in Huangsha Town is almost the same as it was at that time. It also has nothing. It also starts from scratch. It is also mostly illiterate. Lin Ze has seen some relevant information and has repeatedly mentioned similar situations above. Therefore, the blast furnace ironmaking technology at that time was most suitable for Lin Ze's current situation.
　　 chose the blast furnace ironmaking process because the blast furnace ironmaking process is relatively simple and easy to be mastered by workers. In addition, the final production volume is large, the labor production efficiency is high, and the energy consumption is low.
　　 Therefore, even when Lin Ze came to the mainland of Shenzhou, those developed countries were preparing to phase out blast furnace ironmaking, but this method is still the process adopted by most steel plants in the world. For China, which is now extremely backward, this is already the top ironmaking process.
　　 Of course, it does not mean that the mainland of Shenzhou must be worse than that from the earth.
　　 If you really want to say this, then you are very wrong. There is a world of cultivators on the mainland of China, and there are even more magical cultivators here.
The smelter's smelting means are much more powerful than the steel-making technology on the earth. The spirit materials they have made in their hands, and the steel-making methods on the earth, can't be copied at all, even if they can copy it by chance, The price and money that need to be paid are really not affordable by ordinary countries.
　　Not to mention the other, it is the low-level spirit material of black iron alone. If you really want to get it to the earth, it will definitely kill countless materials scientists.
　　 Therefore, don't think that the blast furnace cannot be realized in Lin Ze's hands. There is a refining master, and the refining of the blast furnace is really not a problem.
The only regret is that the blower equipment, Lin Ze is still unable to do the blower using the internal combustion engine or other modern machines as the power of the blower like the later generations, even because of the lack of water in Huangsha Town, he used hydraulic power No, he can only replace it with a blower driven by animal power, which will reduce the production capacity.
　　 However, even so, compared to Linshacheng and other backward ironworks, Linze's production capacity is already amazing.
　　 First of all, the site selection, considering the relatively large body of the fire armor, so this time the scope of the steel plant needs a relatively large place.
Two days later, Lin Ze quickly selected a place, which is located in the west of Huangsha Town. The terrain is flat and wide, and there are no plants around. So, a lot of effort was saved, and it only cost three In the world of heaven, the area of ​​ten football fields is directly leveled out.
The west is empty here, and there is a distance from Huangsha Town. Pollution and the like will not float to Huangsha Town, and it is not far from the barracks. After that, as long as the cement road is paved, the army can arrive in half an hour, so , This is definitely a suitable place.
　　After choosing a place, Lin Ze began construction.
He specially refined some animal power tools and built more than ten large and small animal power borrowing facilities. In order to ensure enough animal power, Lin Ze dispatched more than 300 headed four-layered fire armor cattle this time to provide smelting. The power required.
　　 The east is a long row of bricks, half-buried in the underground charcoal kiln, half-buried underground can effectively maintain heat and improve the utilization rate of raw materials. Its structure is similar to a small two-story building, the first floor is used for fire heating, and the second floor is placed with raw wood for burning charcoal.
　　 This place is not far from the iron ore mine on the side of Mozhen. A little further away is convenient for a large amount of limestone. The only drawback is that there is no coal mine nearby.
　　However, the weight of coal after refining into coke is light, and now the cement road is under full construction, so it can be shipped directly when the time comes. There is a fire armor and there is no need to spend much effort.
After choosing the place, Lin Ze summoned the craftsmen in the engineer battalion, plus the people who had already recruited them, there were a total of three or four thousand people, so they entered the chosen venue here and set about building the first one. Steel Plant.
　　 First is the furnace body, which is made of refractory bricks, the gaps are filled with mud, and then the outside is piled with ordinary bricks, and finally sealed with a layer of cement to ensure that it is both insulated and strong.
　　Blast furnace body is divided into 5 parts from top to bottom: furnace throat, furnace body, furnace waist, furnace belly and furnace hearth.
Lin Ze had no experience in constructing a steel plant. He only knew that he had groped forward with his men based on the theory in the drawings in the Plane Seed World. Among them, it can be said that Nine Layers and Nine had not actually been seen. Talent, a large number of smelter masters were mobilized, and under the full research of everyone, plus Lin Ze carefully experimented in some small steel mills in the plane seed world, so he quickly groped for the cultivation Boundary version of the blast furnace.
　　 Then ~EbookFREE.me~ opened a feeding hole in the top of the furnace to load iron ore, coke, limestone (as a flux for slagging).
　　Under the furnace, open the air outlet and connect the air pipe to blow in the preheated air.
The animal power on one side drives the blower, and the blown wind passes through the air pipe to a short furnace, where the waste discharged after the blast furnace iron is smelted is placed, and the heat is used to preheat the passing air. Then through the air duct, into the blast furnace.
　　 Coke is already available. Lin Ze had established an ancient local coke refining factory not far from the coal mine, and there were still many coke made from coal.
　　After so busy for a few days, everything was finally ready.
According to the above records in the data, in ironmaking, carbon in the coke and oxygen blasted into the air at the high temperature in the blast furnace produce carbon monoxide to remove oxygen, sulfur and phosphorus in the iron ore during the ascent in the furnace , Reduction to get iron.
　　The molten iron is released from the iron port. Unreduced impurities in the iron ore are combined with flux such as limestone to form slag, which is discharged from the port to the low furnace.
As for the waste gas such as the gas produced by Zhihong in this refining process, Lin Ze wanted to use it. However, with her current ability, it is not possible to continue to use it, and, with his current technology, it is also dangerous to use it. Very high, so it can only be discharged in vain.
