Brief introduction of converter steelmaking

Converter steelmaking takes molten iron, scrap steel and ferroalloy as the main raw materials, and the steelmaking process is completed in the converter by relying on the physical heat of molten iron itself and the chemical reaction between molten iron components without the help of external energy. Converter is divided into acid and alkaline according to refractory materials, and there are top blowing, bottom blowing and side blowing according to the position where gas is blown into the furnace; According to gas types, it is divided into air converter and oxygen converter. Oxygen top-blown converter and top-bottom combined-blown converter are the most widely used steelmaking equipment at present because of their high production speed, large output, high output per furnace, low cost and low investment. Converter is mainly used for producing carbon steel, alloy steel and smelting copper and nickel.
