для шлифования и пескоструйной WA / WFA

Description:WA/WFA, a kind of high-grade refractories, 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. The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.Usage:(1)It can make the abrasive tool to grind the great hardness material, such as the high speed steel, stainless steel and high carbon steel.(2)It also usually used for sandblasting, such as precious metal, the gold, crystal, the glass andcowboy wear.The chemical and physical analysis:MODEL:JIS#14 Chemical compositions Physical propertiesItemsValue of specification (%) ItemsPropertyAl2O3 99.55minColorWhiteSiO2 0.04max Bulk density1.75-1.95g/cm3Na2O 0.22max Grain density3.90g/cm3 minFe2O3 0.04maxhardnessMorse hardness9Micro hardness21600-22600kg/mm3Usagegringding polishing and sandblastingcontent of magnetic substance0.0023%maxMills:white fused alumina plantsbrown fused alumina plantsblack silicon carbide plantsgreen silicon carbide plantsMore details: JIS#10-JIS#240(1)It can make the abrasive tool to grind the great hardness material, such as the high speed steel, stainless steel and high carbon steel.(2)It also usually used for sandblasting, such as precious metal, the gold, crystal, the glass andcowboy wear.JIS#280-JIS#4000(1)Itcan be used in grinding and polishing the gold, silver jewellery, the eye glass, bearing andany kind of precision instrument.(2)It can be used in manufacturing the superfinishing stone.(3)It can be used in making the superior refractory products.0-1,1-3,3-5,5-8mm and 180,200,240,280,320FIt is usually used for refractory material.
