Reburned magnesite It is mainly made of 46% magnesite ore, which is calcined at 1600 ℃ - 1800 ℃ through a layer of coal and a layer of magnesite in Tiepi Jianyao. The production process is that two tons of ore can produce one ton of heavy burned magnesia, which can be divided into three grades; 1、 In front of the kiln, the magnesia is burned again. Second, under fired magnesia is burned again. Third, large pieces of magnesia are burned again. The main color of the product of the magnesia is hard reddish brown. The product of the magnesia is characterized by high fire resistance.
Purposes of calcined magnesia products: the products are used for magnesia bricks, magnesia alumina bricks, magnesia chrome bricks, gunning materials, castables, dry materials, coating materials, furnace repairing materials, asphalt, casting, fire prevention and insulation materials, flux accessories, electrical steelmaking furnaces, heating furnaces, rotary furnaces, steelmaking, electric furnace bottoms and ramming furnace linings.
Reburned magnesite
Macrocrystal Fused magnesia The product is mainly made of 0-3 particles of magnesium oxide with more than 90% content, which are melted in an electric arc furnace. This product has high purity, large crystal grain, compact structure, strong slag resistance and good thermal shock stability. It is an excellent high temperature electrical insulation material and an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and unshaped refractory materials. It is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc.
