  • Process of Steel-making from Iron Ore Huaruo

    Thus, it is possible to make steel by purifying pig iron by removing some of the carbon, or by adding carbon to wrought-iron. Iron is found mainly in iron ore in the form of oxides. To reduce iron ore to pig iron, modern technology adopts coke, coal, heavy oil, natural gas and other fuels in the blast furnace combustion, generating a lot of heat and reducing gas, creating the necessary conditions for iron ore

  • The Method of Making Steel from Iron Ore Huaruo

    Making steel from iron ore methods can be generally divided into converter steelmaking and open-hearth steelmaking. Now they are introduced as follows: 1. Converter steelmaking process. The oxidant used in this method of iron ore steelmaking is oxygen. Air is blown into molten raw iron ore to oxidize impurities such as silicon and manganese.
