Model Number: hongtai
Minimum Order Quantity:



The fused white corundum is made of industrial alumina or calcined alumina as raw material and melted at high temperature in an electric arc furnace. It is an important raw material for making high-grade refractory materials, and is also widely used in the abrasive industry.

The fused white corundum • Instructions for use

The fused white corundum is made of high-quality alumina powder and is electrolyzed and refined. Its hardness is slightly higher than that of brown corundum. It has slightly lower toughness, high purity, good self-sharpness, strong grinding force and low calorific value. High efficiency, acid and alkali corrosion resistance, high temperature resistance and good thermal stability. It is used to make abrasive tools, which are suitable for cutting carbon, high speed and just high. It can also be used as grinding, polishing materials, precision casting, spray materials, chemical catalyst carriers, special ceramics, advanced refractories, etc.

Electrofusion white corundum • production process

The fused white corundum is a medium-to-high-grade refractory raw material with white color and dazzling appearance. The white corundum has the advantages of large bulk density and low porosity, which can effectively improve the volume stability and thermal shock resistance of the material. The fused white corundum is the main raw material for the production of high-grade indefinite and shaped refractory materials. It is used for large-scale ladle castables, medium and high-grade iron trench castables, spray materials, prefabricated parts and other amorphous refractories and corundum bricks, corundum and Mullite corundum body, refining corundum porous plug brick, integral spray gun and composite nozzle, high temperature industrial kiln lining and other corundum products. Widely used in steel, cement, ceramics, abrasives, petrochemical and other industries.
