Our brown fused aluminum oxide is made into many shapes and grit sizes ranging from macrogrits to microgrits and powders and be used for abrasive media such as for the raw materials of grnding wheels sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding etc.
Brown Corundum / Brown Fused Alumina /Brown Fused Aluminum Oxide/ Brown Aluminum Oxide
Brown Aluminum Oxide is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard. High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.
Characteristic:As there is high temperature, corrosion resistance, high strength properties, it can be for material of refractory bricks. it poured with steel sliding gate, smelting rare metals, special alloys, ceramics, iron-smelting furnace of the lining (walls and tubes); physical and chemical containers , spark plugs, heat-resistant anti-oxidation coating.Due to high hardness, wear resistance, high strength characteristics, in the chemical system, used for a variety of reaction vessels and pipelines, chemical pump parts; to do mechanical parts, various molds, such as the Roberts mold, extrusion die nozzle pencil lead, etc.; do tool, die grinding, bulletproof material, the human body joints, sealing ring mold. Corundum heat preservation material , such as lightweight corundum brick, corundum hollow ball and fiber products, widely used in a variety of high-temperature kiln furnace walls and roof, both high temperature-resistance and heat-preservation.
Applications for refractory industrial:
Unshaped refractory, stereotypes refractory, castable, ladle refractory, blast furnace hot air furnace series combination brick, high alumina brick, carbon refractory, mullite brick, gun mud, Bulk materials, ceramic bricks, composite bricks, corundum products, charge, pound, refractory raw materials, abrasive raw materials, used in steel mills, foundries, glass factory high-end refractories.
Applications for abrasives:
1.For the raw material of Unshaped and shaped refractory
2.For Friction products and abrasion resistance ground,
3.For Resin or ceramic bonded abrasive,such as grinding wheels,cutting off wheels.
4.For Grinding and polishing ,such as gringing stone, Grinding block, flap disc.
5.For Coated abrasives,such as abrasive paper,abrasive cloth,abrasive belt,Guze.
6.For Producing mold of precision casting and Grinding, lapping and polishing media.
7.For Shot-blasting, such as for sandblasing oil piple , ship and tanks with non magnetic.
8.For Structural And Plate Steel Maintenance.
