Explanation
The process, method and process of making steel. In ancient times, steel smelting was mainly completed in solid state. Modern steelmaking is carried out in liquid state at about 1600 ° C. The main raw materials for steelmaking are pig iron, scrap steel and sponge iron produced by direct reduction method. The main task of steelmaking is four decarbonization (decarburization, desulfurization, dephosphorization, deoxidation), two removals (removal of gas and inclusions), and two adjustments (adjustment of chemical composition and molten steel temperature). The main steelmaking methods include converter sleelmaking method, electric steelmaking method, open hearth steelmaking method (also known as martin furnace steelmaking method, which has been eliminated), and some special steelmaking methods to produce high-quality steel for special purposes, such as electric slag remelting method, vacuum metallurgy method, direct steelmaking process method of steelmaking with iron ore, etc.
