Function characteristics of white fused alumina sand: It will not affect the color of the workpiece; It can be used for sand blasting in the process of prohibiting iron powder residue; micro powder grade is very suitable for wet sand blasting and polishing; high processing speed and good quality; the content of iron oxide is very low, which is suitable for sand blasting operation in which iron slag is strictly prohibited; Remove impurities by pickling. White corundum abrasive treatment Many advantages of white fused alumina abrasive contribute to its important application in industry, but the waste of white corundum abrasive used in workpiece processing has become the main problem faced by enterprises. When white fused alumina abrasive is used, abrasive precipitation will occur. Of course, there will be other sundries on the workpiece. If the two are combined, the difficulty of cleaning will be further increased.
Brown fused alumina is manufactured in electric arc furnace, using bauxite as raw material. High hardness and toughness, it is an important raw material of abrasive and refractory industries. It can be used for belt, ceramic, coated, high-grade, and organic abrasives.
The product can be used as abrasive and refractory material. The abrasive tools made by brown fused alumina are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze, etc. Brown fused alumina can also be used for making fine quality refractory.
Brown aluminium oxide has high toughness. Micro hardness is 1800-2200kg/mm2, abrasive articles made of it are suited for grinding metals of high-tensile strength such as steel, annealed malleable iron and hard high-class refractory products.
The application scope of brown fused alumina:
1. For abrasive
2. For refractory materials
3. For sandblasting abrasive
4. For abrasion resistance ground
5. For producing mold of precision casting.
Brown aluminum oxide abrasive is fused and crystallized under high temperature from a mixture of bauxite and other materials. It is characterized by its high hardness, good toughness and sharp shape in particles. Suitable for grinding metals of high-tensile strength such as carbon stele, general purpose alloy steel, malleable cast-iron and hard bronze etc.
Brown Fused Alumina (BFA) is produced by a reduction fusion of high quality bauxites in electric arc furnaces. It is both a hard and tough material with high strength, making it an excellent abrasive grain for applications such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding. Its thermal properties make it an excellent raw material for refractory applications.
Application Range
Abrasive: Produce ceramic grind wheel, resinoid grinding wheel, Grinding stone, Grinding block, sand paper, sand cloth, sand belt, polish wax, abrasive paste, coating etc..
Refractory material: Mainly used for abrasion and high temperature resistant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc..
Sandblasting abrasive: Mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove oxide skin etc..
Abrasion resistance ground: Mainly used for non-slip of airport and road, chemical factory board paving.
Precision casting: Investment casting technics of stainless steel and aluminium casting in coating.
White fused alumina for abrasive and refractory belongs to the group of electro-corundum. It is produced by controlled melting of alumina in an electric arc furnace. White fused alumina is iron-free, ultra pure and extremely hard.
White fused alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of alpha alumina. Ingots are crushed, ground, and precision screened in our new sizing plant to obtain very consistent sized fractions. Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products. Close sized fractions are available or precision blended to specification. This process ensures a very consistent sizing from coarse to fines which is critical in many applications.
White aluminum oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory.
