Product Description

White fused alumina refractory  section sand (White corundum), was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. White corundum is a high-level refarctroy raw material with Al2O3 purity up to 99%.It can work as refractory castable, aggregate,refractory coating etc.
White fused alumina refractory  section sand is produced by using high-quality white corundum blocks through various processes such as crushing, shaping, and screening. White fused alumina refractory  section sand is resistant to acid and alkali corrosion and has high toughness.
Features of white corundum segment sand:
1. White, harder and brittle than brown corundum, with stronger cutting force, good chemical stability, and good insulation.
2. It has the characteristics of high purity, good hardness and strong wear resistance, so it is often used as an abrasive and is also used for fine grinding of stainless steel and other materials.
Uses of white corundum segment sand:
1. After white corundum is crushed and screened, it can be divided into white corundum segment sand, which generally refers to white corundum products of 1-0mm, 3-1mm, 5-3mm, 8-5mm and other models. Use it to make abrasive tools, suitable for grinding high-speed steel, high-carbon steel, etc.
2. Widely used in bonded abrasives, coated abrasives, polishing and precision casting industries, and in the production of advanced refractory materials.
3. It can be used for solid structure and coated abrasives, wet or dry spray sand, suitable for ultra-precision grinding and polishing in the crystal and electronic industries.
4. White fused alumina refractory  section sand will be used in rough steel smelting. Because white corundum segment sand has high high-temperature strength and good fire resistance and corrosion resistance, it is often used as refractory materials.
