Super Chief

　　 The pig iron fragments melted, and the next thing is easy to do.

　　 The next thing is nothing more than mixing with a kaolin stick made of kaolin + bone meal, and then adding crushed pig iron particles to it.

　　 In fact, this time I used a crucible to smelt these pig irons, and Shixiong used the steel-frying method. The steel filling method has to wait until the iron ore is smelted into molten iron before using it. To smelt such a small amount of pig iron now, it is naturally the most suitable to use the steel method.

　　 Seeing pitifulness in the sky, the tribe couldn't find a tool to stir the molten iron. In desperation, the stone bear had to fire a few kaolin sticks in accordance with the standards for fired refractory bricks. Because only this kind of soil sticks made of kaolin + bone meal can withstand the temperature of molten iron. ????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

　　 I just don’t know if using this kind of soil rod to stir molten iron will produce other chemical reactions.

　　 But now Shixiong really has no choice. A very important step of the steel frying method is to continuously stir the molten iron to allow the sulfur, phosphorus, carbon and other elements in the molten iron to react with external oxygen, thereby reducing the carbon content in the molten iron and removing impurities. purpose.

　　 Of course, adding pig iron particles to the molten iron is also a very necessary step in the steel frying method. It's just that the tribe doesn't even have a grinding disc. These pig irons can only be smashed into tiny particles with a hammer...

　　 Anyway, everything is really simplified, but it doesn't work if you don't. The conditions are here. The so-called Qiaofu is for cooking without rice, and this is the truth.

　　 As for how long it is to stir and how many pig iron particles are added to the molten iron, to be honest, Shi Xiong has no idea. In addition to keeping things simple, you have to rely on Meng!

　　 Anyway, when the pig iron began to melt, another bonfire was lit on the side of the stove. Under the order of Shixiong, several tribesmen put the fired kaolin molds on the bonfire to bake.

　　 This move made these people even more puzzled. They have roasted meat, corn and other grains, but they have never roasted something like this made of mud.

　　 Ishikuma will not explain to them why they did this now.

The mold must be heated before pouring the molten iron, otherwise you will pour the hot molten iron into the cold mold, which will cause a tragic disaster-the mold will explode 100% of the time.. ....

　　 In the end, Shi Xiong estimated that it was almost done, so he personally picked up one of the few iron spoons in the tribe and began to scoop out the molten iron from the cauldron.

　　 The yellow and white molten iron was quickly scooped out by the iron spoon, and then quickly poured into the kaolin molds that were roasted at a temperature of six to seven hundred degrees. The next step was to wait for the molten iron in these kaolin molds to cool.

　　 As for the heat treatments such as quenching and tempering, Shixiong can't take care of it anyway. He doesn't understand these heat treatment techniques, so he can only use this most primitive method to cast what he needs.

　　 The molten iron smelted after smashing the three large iron pans gave Shi Xiong a total of three ploughshares, two tongs, a short machete, three spearheads and more than a dozen arrows.

　　 Ishikuma also wanted to know how the performance of these things he had produced, but it takes a long time for the molten iron to cool down naturally, which is no shorter than the time required to melt the pig iron.

　　 So after all this was done, Shi Xiong ordered the fire to be put out. After arranging a few people to watch the molds where the molten iron was poured, he turned around and went back to rest.

　　 This small pot of molten iron consumed most of the day. The most important thing is that Shi Xiong was always worried during the whole process. His concentration was highly concentrated, which was also a great consumption.

　　 So when everything settled down, even Stone Bear couldn't hold it anymore.

　　 In contrast, the people who have been watching for a long time have been discussing enthusiastically one by one.

　　 For them, what happened today is something they have never seen or even imagined. The white flames coming out of the furnace, the little bit of molten pig iron, and the tribesmen who were constantly stirring the molten iron with a long clay stick but were screaming and screaming all made them realize that they are today. What happened is really remarkable.

　　 Apart from anything else, the ironware that could never be melted in their eyes turned into a pot of molten iron, which shocked them inexplicably.

　　 Many people in the tribe have witnessed three precious iron pots being smashed and thrown into the earthen pot made of mud, and then burned and melted, and finally turned into strange shapes in the mold.

　　 Therefore, most of the people in the tribe are discussing what the Guardian-sama finally made.

　　 And this kind of discussion went on all night.

　　 Early the next morning, the whole tribe began to lively again. Countless tribesmen who were aroused by curiosity all walked out of the house~www.readwn.com~ and quickly gathered in the clearing in the middle of the tribe. Of course, they also saw the few on-duty tribesmen screaming halal Sleep like embarrassment.

　　 After a night of natural cooling, the molten iron in the mold has already been completely cooled down and adhered to the mold.

　　 Shixiong came over with a stone hammer in the company of several people. Yesterday, the guardian's series of performances caused many people to spontaneously support him.

　　 got close to the molds and spit up, but there was no response. Shixiong lifted a mold on a flat rock with confidence, then raised his hammer and smashed it down.

　　 The mold made of kaolin + bone meal shattered immediately, leaving a complete casting.

　　 These are a few arrows, which are the "least valuable" of this batch of castings, so Shixiong plans to use one of the arrows to do an experiment.

Although during the smelting yesterday, the wood planer faithfully recorded all the key data such as the addition ratio, smelting time, mixing time and so on with the weird rich man, but Shi Xiong had no idea about these things that he had produced. Bottom, so he needs to experiment.

　　 This arrow is about five centimeters long and is a flat, tapered arrow. The whole body is dark, and there are many mold particles on it.

　　 Ishikuma took the arrow and rubbed it fiercely on the flat large rock, and quickly wiped off the black oxide on the side of the arrow. Of course, the large rock also left clear scratches.

　　 Li Lei, Gao Niu, Kabulu Sacrifice, and some prominent people in the tribe all gathered around the stone bear to watch the operation of the stone bear. Seeing that there were many scratches on the big hard rock by this small arrow, the faces of several people suddenly blossomed with joy.
