In the smelting process of iron and steel products, due to factors such as smelting time, holding time, and overheating time, the smelting loss of carbon in the molten iron increases, resulting in a decrease in the carbon content in the molten iron. As a result, the carbon content in the molten iron does not reach the theoretical value expected for refining. Carbon-containing substances added to make up for the carbon content burned during the steel smelting process.
