Red Sea Machinery Brown Corundum No. 16, No. 46, No. 60, No. 80, No. 100, No. 120, No. 180, No. 200, No. 280, commonly known as emery, is a brown artificial corundum made by melting and reducing bauxite, carbon materials and iron filings in an electric furnace, so it is called brown corundum. The main chemical composition of brown corundum is AL2O3, which contains 94.5% - 97%, and a small amount of Fe, Si, Ti, etc.
Brown fused alumina is one of the basic abrasives because of its high hardness and good toughness. Its main functions are as follows
(1) Due to the high temperature resistance, corrosion resistance, * * * degree and other properties, steel pouring sliding nozzle is used to treat the lining (wall and pipe) of dilute * * *, special alloy, ceramics and iron making blast furnace; Physicochemical ware, spark plug, heat-resistant * * * coating.
(2) Due to its high hardness, good wear resistance and high strength, it is used as a component of various reaction vessels, pipelines and chemical pumps in the chemical system; Make mechanical parts and various moulds, such as wire drawing mould, pencil lead extrusion mould mouth, etc; Make * * *, mold abrasives, bulletproof materials, human joints, sealing mold rings, etc.
(3) Corundum insulation materials, such as corundum light bricks, corundum hollow balls and fiber products, are widely used in the furnace walls and roofs of various high-temperature furnaces, which are both resistant to high temperature and heat preservation.
Brown corundum grain size sand is manually selected from brown corundum blocks and processed by roller, ball mill, Bamak and other equipment. The grain size is F8-F325. It is mainly used for polishing, grinding, industrial grinding, etc. It can also be processed by water washing, acid washing and other methods according to customer requirements, which can meet the different needs of customers.
