Brown corundum function and production process


Brown corundum function (1) Because of its high temperature resistance, corrosion resistance, high strength, etc., it uses steel sliding nozzles to smelt rare metals, special alloys, ceramics, and iron linings (walls and pipes); Spark plug, heat-resistant and oxidation-resistant coating.
(2) Due to the characteristics of high hardness, good abrasion resistance and high strength, it is used as a component of various reaction vessels and pipes and chemical pumps in chemical systems; it is used for mechanical parts and various molds, such as wire drawing molds, Squeeze the tip of a pencil core, etc .; make knives, mold abrasives, bulletproof materials, human joints, seal mold rings, etc.
(3) Corundum insulation materials, such as corundum light bricks, corundum hollow balls and fiber products, are widely used in furnace walls and roofs of various high-temperature furnaces, which are resistant to high temperatures and heat. Brown corundum grain sand is processed by hand-selected brown corundum blocks, using rollers, ball mills, Barmac and other equipment. The grain size is F8-F325. It is mainly used for polishing, grinding, industrial grinding, etc., and can also be customized according to customer requirements. It can be processed by water washing, pickling and other methods to meet the different needs of customers. Brown corundum can only be produced in accordance with national standards in order to ensure quality. Less direction. On the surface, the price of brown corundum abrasives has increased. Brown corundum is an aluminum ore (also known as bauxite, scientific name gibbsite) that can be formed over hundreds of millions of years. After high temperature baking and dehydration, it is mechanically crushed, and then blended It is smelted from other materials by electric furnace. The smelting furnace, known as the electric tiger, is a high-pollution and high-energy-consumption device. It currently requires about 3,000 degrees of electricity to produce one ton of corundum. Brown alumina and in April the national government increased its efforts to implement the 2008 environmental protection and energy conservation and consumption reduction targets. "Efforts to promote energy conservation and emission reduction to a new level have actually saved resources and achieved improved resource utilization. The purpose is to greatly reduce the gap between Chinese abrasives and coated abrasives and their counterparts in the world and achieve early integration. Speaking of the future development direction of China's brown corundum abrasive industry, individuals tend to increase the overall size of the industry, Scale, economy and energy saving.
