[Note]: Lump fluorspar size depending on consult with customers [Usage]: mainly used a flux in the manufacture of steel in basic open hearth ,basic converter and electric hearth in metallurgic industry . It can enhance the fluidity of slag and promote the entry of sulfa and phosphor into slag ,thus improve the quality of steel . It can also be used in metallurgy of non-ferrous metal ,welding material, optical elements, decoration of lampsand lanterns and fluorspar carving craftwork . [Packing]: bigger size in bulk; smaller size using weight 50KG or 1000KG bags.
