[0002] Steel can be divided into many types according to the carbon content, carbon structure, whether it contains other alloys, and the amount of other alloys contained in the steel, and each type of steel has different uses. Converter steelmaking uses molten iron, scrap steel, and ferroalloys as the main raw materials. It completes the steelmaking process in the converter without the help of external energy sources, relying on the physical heat of the molten iron itself and the heat generated by the chemical reaction between the components of the molten iron to generate heat. Converters are divided into acidic and alkaline types according to refractory materials, and top blowing, bottom blowing, and side blowing according to the location where the gas is blown into the furnace; according to the type of gas, they are divided into air converters and oxygen converters. Alkaline oxygen top blowing and top and bottom combined blowing converters are the most commonly used steelmaking equipment due to their fast production speed, large output, high single furnace output, low cost, and low investment. Converters are mainly used for the production of carbon steel, alloy steel, and the smelting of copper and nickel.
