First-grade fused white corundum 46#-70#, first-grade high quality, stable quality

White corundum is made of high-quality aluminum oxide powder as raw material and is refined and crystallized by electric fusion. It has high purity, good self-sharpening properties, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than brown corundum. Slightly lower toughness, high purity, good self-sharpening, strong grinding ability, 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 grinding high-carbon copper, high-speed steel, etc. Fused white corundum is a medium-to-high-grade refractory raw material with a pure white color and eye-catching crystal. It has the advantages of high volume density and low porosity, and can effectively improve the material quality. Volume stability and thermal shock resistance. Fused white corundum is the main raw material for the production of medium and high-grade indefinite and shaped refractory materials. It is used for large ladle castables, medium and high-grade iron trench castables, gunning materials, prefabricated parts and other unshaped refractory materials and corundum bricks, corundum and Mullite corundum box bodies, corundum porous plug bricks for refining, integral spray guns and composite nozzles, high-temperature industrial kiln linings and other corundum products. Widely used in steel, cement, ceramics, abrasives, petrochemical and other industries.
