The reaction principle of pig iron to steel
The carbon content in the pig iron is removed by smelting to reach the carbon content of the steel
The difference between material for blast furnace, coke, iron pig iron and iron is iron containing carbon black, coke is to provide carbon materials as long as the iron in the blast furnace after high temperature baked iron is its hardness is very large but not good toughness so the pig iron into steel repeatedly Chuida until the difference is pig iron by hammering carbon element reduced
The principle of steelmaking is to use oxygen or iron oxides to convert excess carbon and impurities in the pig iron into gas and slag removal. The carbon content is controlled at 0.03%-2% and the steel is tempered
