Fluorite powder is used in the metallurgical industry. The fluorite powder contains halogen element fluorine, which can reduce the melting point of refractory substances, promote the flow of slag, separate the slag and the metal, and desulfurize and dephosphorize during the smelting process, and enhance the forgeability and tensile strength of the metal. Strength and other characteristics. Therefore, it is widely used as a fluxing agent in steel smelting and ferroalloy production, iron smelting and non-ferrous metal smelting.
