Recarburizer

In the smelting process of iron and steel products, due to factors such as smelting time, holding time, and longer overheating time, the smelting loss of carbon in the molten iron increases, resulting in a decrease in the carbon content in the molten iron. The carbon content in molten iron does not reach the theoretical value expected for refining.

The carbon-containing substances added in order to make up for the carbon content lost during the steel smelting process are called recarburizers.
