Super Chief

　　 Early the next morning, the whole tribe became lively.

　　 Yesterday, Lord Guardian hunted and killed a bison alone. This was a great event for the entire tribe. And having meat for two days in a row has further improved the reputation of Stone Bear among the tribe.

　　 After a cow is slaughtered, about 45% of beef can be produced under normal circumstances. However, unlike the white people who believe in **** Christ, North American Indians do not eat the offal of animals. North American Indians eat almost everything.

　　 As the elite foodies of the big food empire, the stone bear is naturally more concerned about offal. On the contrary, for the stone bear, the offal of the bison is more delicious than beef.

　　 Therefore, this poor cow demon may still be able to preserve the horns, bones, and hides of the cow. It is estimated that all other parts of his body will be eaten by this group of Indians.

　　 The clansmen responsible for the slaughter in the tribe kept all the internal organs according to Shixiong's instructions. These internal organs need to be well soaked in order to make delicious offal. However, Shixiong has no time during the day, so early in the morning, after eating a few chunks of beef stewed in white water and salt, he moved a bit and began to prepare the tools for steelmaking.

　　 At first, Shixiong planned to use the crucible to make those pig irons, but after thinking about it, he felt that there was something missing in steel making with the crucible.

　　 Later, he remembered that if he uses kaolin clay as a crucible, there is no graphite in the crucible. The crucible steelmaking method requires a graphite crucible, which requires graphite and pig iron to react at a high temperature to finally produce steel.

　　 But what should I do if I don’t have graphite in my hands?

Later, Shi Xiong finally decided to use the steel frying method, but after thinking about it, he realized that there is no thermometer now, let alone a special thermometer used in the metallurgical industry. Therefore, it is not easy to control the temperature with the steel frying method. Smelt a furnace of molten iron to waste.

　　 Finally, Shi Xiong thought of the steel filling method.

　　This kind of steelmaking method developed on the basis of the technology of the steel fry method is easier to control than the steel fry method, and it can also better control the carbon content of the steel produced.

　　 The most important thing is that in terms of the materials and conditions that I currently have on hand, the steel filling method is the most suitable for my current situation.

　　 Finally, after careful consideration, Ishikuma decided to use the filling method for the first furnace of steel he made!

　　 If you want to use steel filling to make steel, filling furnaces and blast equipment are indispensable. As for the fuel, there is no more suitable fuel than coke. However, coke also requires special refining, which is more troublesome, but this is not a problem.

　　 In his previous life, as an associate researcher-level cultural protection expert, Shi Xiong had seen many pots in the Tang and Song dynasties in Sichuan and Henan, and later studied the use of these pots and how to pot steel.

　　In terms of the current level of technological development, open-hearth furnaces and converters, let alone Indians, even European whites don’t have the ability to make them. It will take more than a hundred years for these things to be invented and manufactured. Now to make steel, you can only use the steel frying method or the steel filling method.

　　Under the current technological conditions, the highest temperature that humans can reach in metallurgy does not exceed 1,400 degrees Celsius, so it is almost impossible to make high-quality steel.

　　 However, China’s ancestors developed the steel filling method based on the steel frying method, so that the smelted steel material has a certain guarantee.

　　Ishikuma now does not have high requirements for the quality of steel. As long as the steel can be produced, it is a huge improvement. As for how to make higher-quality steel in the future, it will take more people and more time to do it slowly.

　　The steel filling method appeared as early as the end of the Eastern Han Dynasty, but the use of steel filling method to greatly improve the quality of steel will have to wait until the Northern and Southern Dynasties.

　　 A smelting genius appeared during the Southern and Northern Dynasties, named Qi Wuhuaiwen. This guy is a native of North Qixiang. Later, he once served as the governor of North Qi Xinzhou, and he is considered to be a member of the party.

　　 Qi Wuhuai, who was in the position of official and governor, was also a genius in steelmaking. He made a breakthrough in the development and improvement of the steel filling method that appeared at the end of the Eastern Han Dynasty. At the same time, he also made unique creations in knife making and heat treatment, and made epoch-making contributions to the development of China Metallurgical Technology.

　　 History books once recorded how Qi Wuhuaiwen made steel.

　　 "Bake pig iron, use it to soften the collar, and it will become steel after a few nights."

In modern terms, the meaning of this sentence is to select iron ore with a relatively high level during steelmaking, first smelt high-quality pig iron, and then pour the liquid pig iron on the wrought iron. After several times of smelting, the iron can be penetrated. Carbon becomes steel. Since pig iron and wrought iron are "staying together", the steel produced is called "staying iron".

　　 This was definitely a breakthrough technology at the time.

You know, because the temperature is not well controlled, it is difficult to produce low-carbon steel. Most of the steel produced by the frying method has poor temperature control, resulting in incomplete oxidation of impurities and carbon in the molten iron. , So most of them are some medium and high carbon steel, which is good for farm tools or daily necessities, but it is far from enough to build weapons.

　　The emergence of the steel filling method ~www.NovelMTL.com~ Especially the emergence of the steel filling method modified by Qiwuhuaiwen, making low-carbon steel making has become a controllable method.

In modern terms, when using this method of filling steel to make steel, because pig iron is used as a carburizing agent, the high temperature after melting can accelerate the rate of carburizing into the wrought iron, shorten the smelting time, and increase productivity. .

　　 At the same time, wrought iron becomes steel due to the infiltration of carbon, and pig iron can also become steel due to decarburization, increasing the output of steel. Moreover, at high temperatures, the carbon, silicon, manganese, etc. in the liquid pig iron react with the oxide inclusions in the wrought iron to remove impurities, purify the metal structure, and improve the quality of the metal.

　　The most critical point is that the steel filling method is easy to operate and easy to master. To obtain steels with different carbon content, as long as the pig iron and wrought iron are mixed in a certain proportion and smelted, they can be obtained.

　　 Ishikuma took a look at all the materials he had on hand, and found that the steel filling method is obviously better than the fried steel method.

　　 The iron ore in my hand is hematite. Although I don’t know what the grade is, the grade of hematite is generally high, and it should be able to meet the iron ore requirements of the steel filling method.

　　 The slag-making agent also has limestone itself, as well as the kaolin used to make refractory bricks, let alone fuel coal. As for the pig iron used as carburizing agent, the best carburizing agent will be the best carburizing agent after those big iron pots are broken!

　　With these things, why can't you make steel?

Therefore, under the supervision of the leader of Li Lei and the Kabru sacrifice, and with the encouragement of Shixiong’s promise of meat every day, all the tribesmen in the tribe mobilized and started to do the various pre-steel making activities under Shixiong’s command Kind of preparation.
