Fluorspar Briq is used instead of Fluorspar lump which can  lower  the melting point of the slag to

help the  separation of the slag and steel water in in the smelting process . It's widely used as a flux in alloy

steel smelting production of iron and non-ferrous smelting process.  It is more productive and cost-effective compared with original fluorspar lump due to stable content of CaF2 and  less impurity.
