brown aluminium oxide/emery sand/grinder disc raw material

Introduction of brown emery sand

Brown emery sand is a very refractory, hard and chemically resistant material. It is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000°C.

Corundum is bauxite, coke (anthracite), scrap iron as main raw materials, in electric arc furnace high temperature melting nei crystals into, it has high hardness and great toughness, particle xinfengrui, grinding force is powerful, high temperature resistant, the efficiency high characteristic, is the quality of abrasive abrasive materials and advanced refractory materials. Makes with it, apply to the abrasive high-tensil strength high metal, can cut, grinding various general steel, carbon steel, alloy steel, general malleable green steel, hard to wait, also can green steel as senior refractory materials, widely used in steel, chemical and other industries.
