Refractory Material White Corundum Powder made from High Alumina Bauxite Source

 Electrofused white fused alumina is made of industrial alumina or calcined alumina as raw material by melting at high temperature in an electric arc furnace. It is an important raw material for making high-grade refractories and is also widely used in abrasive industry.

Electrofused white fused alumina • Instructions for use
Electrofused white fused alumina is made of high quality aluminum oxide powder as raw material, refined and crystallized by electrolysis. Its hardness is slightly higher than that of brown corundum, toughness is slightly lower, purity is high, self-sharpening is good, grinding force is strong, calorie-generating is small, efficiency is high, acid and alkali corrosion resistance, high temperature resistance, thermal stability is good.Made of abrasive tools, suitable for cutting high carbon steel, high-speed steel, etc.Can also be used as grinding, polishing materials, precision casting, spraying materials, chemical catalyst carrier, special ceramics, senior refractory materials, etc.

Electrofused white fused alumina • production process
Electrofused white fused alumina is a kind of high-grade refractory raw materials, white color, glittering and translucent, white fused alumina has the advantages of large volume density, low porosity, can effectively improve the volume stability of the material and thermal shock resistance.Fused white fused alumina is the production of high-grade ambiguity and shaped refractory material of main raw materials, used in large ladle castable, high-grade iron ditch castable, gunning materials, fabrication of monolithic refractories and corundum brick, just the quality of the jade and mullite Shi Gang jade XiaTi, refined with corundum porous plug brick, the whole gun and composite nozzle, high temperature industrial kiln lining material such as a variety of corundum products.Widely used in steel, cement, ceramics, abrasives, petrochemical and other industries.

White corundum is high quality aluminum oxide powder as raw material, white fused alumina by electric fusion refining crystallization, hardness is slightly higher than brown corundum, toughness is slightly lower, high purity, good self-sharpening, grinding ability is strong, calorie-generating, high efficiency, acid and alkali corrosion resistance, high temperature resistance and thermal stability.
Brown corundum, also known as the common name of emery, is the use of bauxite, carbon materials, iron scraps three raw materials in the electric furnace after melting reduction and made of brown artificial corundum, so this name.Brown corundum main chemical composition is Al2O3, its content in 94.5%-97%, another contains a small amount of Fe, Si, Ti and so on.
White corundum, a kind of artificial abrasive.Aluminum oxide (Al2O3) content in more than 98%, and contains a small amount of iron oxide, silicon oxide and other components, is white.
White corundum with industrial alumina powder as raw material, regularly over 2000 degrees in the arc after cooling in high temperature melting, after smashing plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, granular form sharp corners, consolidation is suitable for making ceramic, resin abrasive and grinding, polishing, sandblasting, precision casting, precision casting special corundum), etc., can also be used for manufacturing high-grade refractory materials, code-named "WA" international general standards, national standards are consistent, most for export, supply domestic users also have a certain amount.

White corundum is a kind of suitable for dry and wet two kinds of production process of the most affordable abrasive, white fused alumina is especially suitable for the rough workpiece surface treatment, and after the treatment of the surface and the requirements of the occasion.This sharp, angular synthetic material is second only to diamond in hardness and is often used in applications where iron contamination is strictly required.It can be used to cut very hard materials, but also can be made into balls for the processing of the precise size of the workpiece, to achieve very low roughness.Its high density, sharp, angular structure makes it the fastest cutting abrasive.White corundum is produced by melting high quality aluminates (aluminum oxide powder) to produce powdered corundum and white fused alumina.

 High purity white fused alumina for sandblasting and polishing

White Fused Alumina Production:

1. Add conductive material to the alumina powder, put it in the furnace, dissolve it with electricity, spray water, cool, solidify, and crush to form a block of white fused alumina with an aluminum oxide content of more than 98%.
2. Crush and screen according to the size required by customers. Most of the particles are spherical particles, commonly known as "granular sand", and the general international particle size number is F4-F220.

3. The screened fine powders are sieved through a hydraulic process, monitored in real time under a microscope, and dried to produce white fused alumina powder.

4. Packed in 25 kilograms per bag, and packed in tons of bags per ton, weighed with floor scales, and selected economical transportation methods according to customer needs.
