The heavy burned magnesia is mainly made of 46% magnesite ore, calcined at 1600 ℃ -1800 ℃ through a layer of coal and a layer of magnesite in the iron kiln. The production process is that two tons of ore produce one ton of heavy burned magnesia, and the product is divided into three grades; one, the burned magnesite before the kiln, the second, the under burned magnesia, and the third, the large burned magnesia The main color of the reburned magnesite is hard reddish brown. The features of the reburned magnesite are high fire resistance.
Reburned magnesia product use: The product is used for magnesia brick, magnesia-aluminum brick, magnesia-chrome brick, spraying material, pouring material, dry material, smearing material, filling material, asphalt, casting, fire prevention and heat insulation material, flux auxiliary material, Electric steelmaking furnace, heating furnace, rotary furnace, steelmaking, electric furnace bottom and ramming furnace lining.
Large crystal fused magnesia products are mainly produced by melting 90% or more magnesium oxide 0-3 particles in an electric arc furnace. This product has high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material, and it is also important for the production of high-grade magnesium bricks, magnesium carbon bricks and unshaped refractory materials. raw material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, and household appliance components.
