White fused alumina

White fused alumina, a kind of high-grade refractories, is made from the imported high quality alumina by melting above 2000℃ in the electric arc furnace and cooling. It is white with the main crystal phase α-Al2O3。   The white alumina produced in the titling electric arc furnace has the advantage of high bulk density and low porosity, thus the volume stability and thermal shock resistance can be improved.
White fused alumina is the main starting material to produce high-grade unshaped and shaped refractories and is widely-used in the field of iron &steel industry cement industry, ceramics, Petrochemical industry, etc. It is the ideal starting material to produce the unshaped refractories such as large ladle castables, medium and high grade ladle castables, medium and high grade BF trough castables, gunning material, pre-cast shapes and is the main startirs material to produce alumina products such as corundum bricks, corundum and Mullite-corundum sagger, refined porous plug bricks, monolithic lance & composite nozzle, lining material for high-temperature industrial furnaces, etc.
White fused alumina, used as consolidation & coating abrasives, wet or dry sprayed grit, is suitable for the ultra-precise grinding & polishing in the crystal and electronic industry and can be used to produce high-grade refractories. It is suitable to machine high stiffness and high tensile strength materials such as chilled steel, alloyed steel, high speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc.
