It is also called slagging materials. In order to quickly form slag with proper performance and composition in smelting process, auxiliary materials need to be added, which are widely used in iron and steel metallurgy and non-ferrous metallurgy process. According to its use, flux can be divided into slag forming materials and slagging agent. For example, lime, dolomite, limestone, etc. added in steel smelting belong to slag forming materials, whose main functions are dephosphorization and desulfurization; The added fluorite belongs to slag melting agent, whose main function is to reduce the melting point and viscosity of slag and improve the flow ability of slag.
