Steelmaking is the process of removing the carbon content in pig iron to a specified range and reducing or increasing the content of other elements to a specified range according to the requirements of the type of steel being made. Briefly speaking, it is a process of oxidizing pig iron to reduce carbon, remove sulfur and phosphorus, and adjust the silicon and manganese content. Common methods include open hearth and converter oxygen blowing steelmaking

Converter steelmaking: Pour molten iron into the converter, add a certain amount of scrap steel and steelmaking pig iron to adjust the composition and reduce the temperature, and add a certain amount of quicklime for desulfurization. After oxygen blowing and decarbonization, add a carburizing agent and alloy material to adjust the composition after discharging.
