Abrasives: mainly suitable for: sandblasting, grinding, polishing, cutting discs, grinding wheels, fixed abrasives, coated abrasives, etc.

Refractory materials: precision casting, refractory bricks, castables, etc.

 

 

Raw material: first grade aluminum oxide powder

Production equipment: dumping electric arc furnace; jaw breaker; Barmac sand making machine; magnetic separation equipment; dry cleaning machine; screening equipment; overflow tank; dryer

1. Oxidation (dumping electric arc furnace) smelted crystalline White Fused Alumina entity

2. Natural cooling

3. Crushing and sorting

4. White corundum block

5. Barmac sand making machine for material processing, crushing and sand making

6. Magnetic separation equipment to remove iron, dry cleaning machine to remove dust

6. Use a sieve machine (vibrating screen) to sieve out different specifications and models of white corundum step by step

 

White Fused Alumina is made from high-quality alumina powder and smelted by electric melting. The hardness of White Fused Alumina abrasive is slightly higher than that of brown corundum, with lower toughness, high purity, good self-sharpening, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, and high temperature resistance. It is used to make abrasive tools, suitable for grinding high carbon steel, high speed steel, stainless steel, etc. It is also widely used in various ceramics such as precision casting, steel refractory, chemical refractory, 95 electric porcelain, decorative porcelain and porcelain for daily life, as well as high-tech industries such as military industry and electronics.

 

(1) After pickling step to remove impurities, the amount of iron oxide contained is extremely low.

 

(2) Suitable for sandblasting operations where iron residues are strictly prohibited.

 

(3) Does not affect the color of processed parts.

 

(4) High processing speed and high quality.

 

(5) White corundum powder is very suitable for wet sandblasting and polishing operations

Sandblasting materials are mainly used in surface processing, beautification processing, etching processing, pre-treatment processing, burr processing, stress relief processing, electronic parts processing, mold processing, large workpiece processing, and glass processing. We have introduced the use of white corundum before, so what is the purpose of white corundum abrasives? White corundum abrasives can be used for consolidation and coating abrasives, wet or dry blasting sand, suitable for superfine grinding and polishing in the crystal and electronic industries And the production of high-grade refractory materials. It is suitable for processing hardened steel, alloy steel, high-speed steel, high-carbon steel and other materials with high hardness and high tensile strength. It can also be used as contact media, insulators and precision casting sand.
