The main component of refined fluorspar pellets is calcium fluoride. This product is widely used as a flux in steel smelting and ferroalloy production, cast iron processing, and non-ferrous metal smelting. It can lower the melting point of refractory materials, promote slag fluidity, facilitate effective separation of slag and metal, and assist in desulfurization and dephosphorization during the smelting process, thereby enhancing the metal's forgeability and tensile strength.
