Super Chief

　　Although he has decided to use the earth kiln coking method to make more coke, Shixiong did not plan to let the big pit where the first coking was done so wastefully.

　　 Anyway, the earth kiln coking method also digs a big pit in the ground, so Shixiong decided to reuse the big pit from the previous coking after thinking about it for a while. Of course, this big pit is a bit smaller, so it needs to continue to expand.

With tools such as shovel, hoe, and pickaxe, digging the hole can be much easier. In just one day, the diameter of the large hole used for the first coking has been doubled, and the depth is also according to the stone. What the bear said deepened by more than half a meter.

Then these excited tribesmen started to build the flue with lump coal in accordance with Shixiong's requirements. After the first layer of flue was built, pulverized coal was placed around it, and when it was installed to a certain height, it was leveled and solid, and then the second layer of flue was built... ....

　　 There are so many people and great power.

　　 Although the people of the tribe have not built a flue before, under Shixiong’s guidance, this work is progressing very quickly. So it took only half of the morning the next day, and this kiln coal and the wood used for ignition were all cleaned up.

　　 The next step is to ignite. After all the pulverized coal is ignited, the coking will officially begin.

　　 Although there was no stacking of flue during the first coking, the coking process is almost the same, so with the experience of the first coking, this second coking is much faster.

　　 When a flame with blue smoke came out from the pilot hole, the pilot hole was muddied to death by the clansmen who had been prepared for a long time, and then another group of clansmen began to cover the sand and then poured water to cool down.

Lieutenant Ferguson watched these people making coking under the command of the boss with relish. Although he didn't know why he wanted to do this kind of thing, he was almost completely devoted to the stone bear now, so he had been watching quietly. It was not until he started to sprinkle water to cool down, he quietly approached Shi Xiong and asked in a low voice: "Boss, this kind of thing can really make steel?"

Stone Xiong has given him too many pointers these days, which makes it clear to Lieutenant Ferguson, who usually thinks highly of himself, that this savage and cruel big man is actually a very connotative person, and what he knows is simply so impressive. Looking back, Lieutenant Ferguson had already regarded the stone bear as an idol deep down.

At the beginning, he couldn't say the word "boss" because of his face, but since the rotary valve locking device got the eyebrows, after he called "boss" from his heart, Lieutenant Ferguson never said it again. There is no conflict with this title.

　　 And he thinks that calling this big man the boss really doesn't feel wronged at all.

　　 A boss like this is definitely worth following.

　　 Don't look at this boss who doesn't laugh at ordinary times, but he does things really unambiguously.

　　 Lieutenant Ferguson knew very well that the boss started all the tribesmen who had fallen to start steelmaking, not for anything else, but to be able to have enough steel to use when experimenting with the new gun.

　　 Don't talk about this kind of lip service, but only use practical actions to support his boss, where to look for it!

Shi Xiong glanced at Lieutenant Ferguson next to him, and said in a low voice: "The coke is mainly used for iron smelting after being refined, because the melting temperature of iron ore is higher than that of steel, and the heat generated when ordinary coal is burned. And the temperature is not enough to melt the iron ore, so it is necessary to use coal to produce a fuel that can generate greater heat and higher temperature during combustion, so that the iron ore can be completely melted, thereby smelting molten iron. ."

After a pause, Shi Xiong continued to explain: "Only with molten iron, we can perform further processing when the molten iron is melted, so that real steel can be produced. Well, if the steelmaking furnace can be produced this time You have the right to use one-third of the qualified steel!"

　　 Lieutenant Ferguson was touched again by the last words, this is what the boss looks like!

　　 This time the coking was very successful. With the first experience in coking, the success rate of this coking was as high as 90%, and most of the coal was successfully refined into qualified coke.

　　 And with the success this time, the success rate will continue to rise when coking is done next time!

　　 This time coking, at least 20,000 catties of coal were put into this enlarged earthen kiln, and finally the qualified coke out of the kiln exceeded 13,000 catties. This ratio is already close to the pass rate of subsequent coking.

　　 There is so much coke, enough to open that earthen blast furnace four times!

　　 Of course, the stone bear next to the earth kiln did not let it sit idle during the coking process. Anyway, no matter how coking is made, a large amount of waste heat will be generated. It is a crime not to use this waste heat.

　　 So before coking, Shixiong asked the people to prepare a lot of refractory bricks and some ordinary red bricks.

　　 As a result, after the end of the coking process, there were many more qualified refractory bricks and ordinary red bricks in the tribe.

　　 There are not many red bricks, only a few hundred. But this time the red brick was successfully fired, which is an improvement.

　　 For the primitive tribe of Gaoshu tribe, which is almost nothing, even if it is a red brick, it is also a kind of precious wealth.

　　 And in order for the tribe to develop and grow, a little bit of accumulation is an indispensable process.

　　 These hundreds of red bricks are not many, but they can let the people understand the benefits of red bricks. Whether it is building a house or for other purposes~www.readwn.com~Red bricks are much more convenient than those rocks!

　　The existence of these red bricks is to make the people realize that the red bricks made by firing have a wide range of uses.

　　 In the future, if the tribesmen are mobilized to build brick kilns and burn bricks, the tribesmen will spontaneously stand up and contribute.

　　While making coking, several strong men selected from the tribe are not idle. They are all people who are more interested in ironware or smelting, and they are gathered by the wood planer.

　　 Musha has shown his talent in smelting, and he himself is willing to switch to smelting. Although this made Lao Muo a little unhappy, Lao Muo finally nodded and agreed to his second son's request for a career change.

　　 Therefore, Mu Zao became the manager of the tribe who was specifically responsible for smelting. With his efforts, some tribesmen interested in smelting also joined his team.

　　 Now, these seven or eight strong clansmen are learning to strike iron under the arrangement of wooden planes.

　　 That’s right, after Shixiong’s guidance, Musha decided to train these tribesmen to become specialized blacksmiths in the tribe!

　　Since you want to train a blacksmith, ironing is one of the basic skills that a blacksmith must master.

　　 Well, if Mr. Kobe Bryant can get here from that time and space, this black mamba will definitely become the leader of the tribal blacksmith!

Now these future blacksmiths, under the command of the wood planer, remelt some scrap pig iron from the last furnace in a crucible, then stir it vigorously, and finally take it out with tongs and place it on the iron felt and continuously forge it with a hammer. Finally, the red iron ore was forged into thin iron plates.

　　In this process, these thin iron plates will eventually become low carbon steel with very low carbon content or even wrought iron. These iron plates are prepared for the second steelmaking process!
