1200 Grit Aluminum Oxide Manufacturers Norway

Brown corundum, white corundum, zirconium corundum, microcrystalline corundum, single crystal corundum, chrome corundum, samarium neodymium corundum and alumina sintered corundum are all called artificial corundum. Brown corundum (brown corundum powder) Brown corundum is made of bauxite, anthracite, and iron filings, and is smelted in an electric arc furnace at high temperature.

During the smelting process, the green silicon carbide in anthracite reduces impurities such as silicon oxide (SiO2), iron oxide, and titanium oxide in alumina to metals. These metals combine to form an iron alloy, which is settled to a higher density than the corundum melt. The furnace bottom is separated from the corundum melt. fused alumina has strong anti-breaking ability, anti-oxidation, anti-corrosion, and good chemical stability.


White corundum (white fused alumina fine powder) (WA) White corundum (a-Al2o3) is an abrasive made of aluminum oxide powder heated and melted and recrystallized in an electric arc furnace. The impurities in the raw materials are not excluded during the smelting process. Therefore, The quality of white corundum is closely related to the purity of the raw materials. synthetic corundum can also be used for precision casting and advanced refractory materials. 


It is an abrasive with a wide range of uses. The content of A12O3 in black silicon carbide should be above 97%, its hardness is higher than that of brown corundum, but its brittleness is greater. Mainly used for fine grinding and fine grinding of hardened steel and alloy steel, grinding thread and gear, etc. Microcrystalline corundum (MA) The emery abrasive raw materials and smelting method of microcrystalline corundum are basically the same as those of brown corundum.


After the white aluminum oxide furnace is stopped, the melt is poured into the mold and cooled rapidly (usually within 30 minutes). Thus, an aggregate of fine crystals was obtained. During the smelting process of microcrystalline corundum, the reduction degree of impurities is poor. The content of Al2O3 is 94% to 96%, the crystal size is generally 80 to 300 / tm, the crystals occupy 57% to 85%, and the maximum black aluminium oxide crystal size does not exceed 400 to 600 μm.


It has the characteristics of arc fused alumina high strength and great toughness. It is suitable for heavy-duty grinding. It can grind stainless steel, carbon steel, bearing steel and special nodular cast iron. Because the abrasive particles are in the state of micro-edge breaking during the grinding process, they are also used for brown fused aluminium oxide precision grinding and even mirror grinding. It has good cutting, oxidation and gas corrosion resistance, and has good insulation.


Strengthen the safety management of outdoor feeding staff. The outdoor temperature is low in winter, and the silicon carbide abrasive workers freeze their hands and feet, especially the broken ones. They will be injured if they are not careful. To address this problem, in addition to formulating relevant countermeasures, it is necessary to improve operating conditions. At the same time, white fused alumina price operators will be reminded before daily shifts to minimize unsafe factors.
