Features:
Brown fused is made of bauxite, Coke (anthracite) and iron filings by high temperature melting and crystallization in electric arc furnace, it has the characteristics of high hardness, high toughness, sharp particle front, strong grinding force, high temperature resistance and high efficiency.
It is a high quality abrasive tool material and advanced Refractory. The abrasives made of it are suitable for grinding metals with high tensile strength, cutting and grinding all kinds of general steel, carbon steel, general alloy steel, malleable blue steel, hard blue steel, etc. , it can also be used as an advanced Refractory in steel, chemicals and other industries.
