Brown fused alumina uses bauxite, coke as the main raw material, smelting in the electric arc furnace at high temperature. The composition of brown corundum mainly include al2o3, tio2, also contains a small amount of sio2 and fe2o3, micro hardness is hv1800-2200. The toughness is lower than silicon carbide, higher than that of white corundum, hardness is 9.0, slightly lower than the same level of white fused alumina. Commonly used brown fused alumina can be divided into brown fused alumina powder, brown fused alumina segment of sand, brown fused alumina granular sand. Today, I mainly explain the brown fused alumina powder related knowledge for you.The brown fused alumina powder has moderate hardness, high toughness, good self-sharpening ability, low sand consumption and recyclable use, good abrasion and abrasion resistance, and chemical composition stability, abrasion resistance, acid and alkali resistance. Especially its high hardness, specific gravity large, chemical stability and its unique self-sharpening, etc., so used as the first choice in brown fused alumina abrasive sandblasting process , but also the best choice for cleaning up the work piece. Abrasives made of brown fused alumina powder , suitable for processing a variety of general steel, malleable iron, hard bronze, etc., can also produce high-grade refractories. Brown fused alumina abrasive use high-quality brown fused alumina as raw materials, using modern new unique technology from refining.brown fused alumina sandblasting has characteristics of short grinding time, high efficiency, good efficiency and low price. The abrasive shell-shaped fracture, sharp edges and corners, in the crushing classification in the formation of new edges and edges, so that the grinding ability is better than other abrasives.

classificationWhite fused aluminaQingyun White fused alumina is a high-grade refractory materials, its main crystalline phase is-Al2O3, color white, with characteristics of large volume density, low porosity, volume stability and good thermal shock resistance and other . fused alumina is for large steel castings in daily use, especially type alloy castings, sand core surface coatings and investment casting system shell material, the same time as hardened steel, alloy steel and other semi-fine grinding, abrasive grinding , fused alumina sand, Qingyun White fused alumina powder is the best material layer material in place of zircon sand .The castings made of Qingyun White fused alumina have a good gloss.Performance and advantages of Qingyun White fused alumina grain sand1, does not affect the color of the workpiece;2, can be used to blast in non-iron remaining manufacturing process;3, Powder grade is suitable for wet blasting and polished work;4, processing speed, high quality;5, the amount of iron oxide contained in low iron suitable for sandblasting residues of prohibited jobs.Physical and chemical indicators of Qingyun white fused aluminaAfter-sale Service of Qingyun White fused alumina1, to provide technical guidance in the use of materials;2, answer buyer's consultation;Call recommendations on product qualityfrom the buyer, and timelymake improvement according to the circumstances;4, contact the most reliable logistics and delivery cargo security.Gong yi Qingyun Refractories Co., Ltd. of fused alumina powder with carefully selected production for a block as raw material, through special processing, uniform particle size, high hardness, grinding and strong.
