The difference between dead burned magnesia and large crystal fused magnesia

Dead-burned magnesia is mainly made of 46% magnesite ore, which is calcined at 1600℃-1800℃ through one layer of coal and one layer of magnesite in iron kiln. The production process is that two tons of ore produce one ton of dead burned magnesia. The products are divided into three grades; one, dead burned magnesia before the kiln, two, underburned dead burned magnesia, and three, large pieces of dead burned magnesia, The main color of dead-burned magnesia products is hard reddish brown, and the characteristics of dead-burned magnesia products are high refractoriness. Light Burnt Magnesium Ball

Dead-burned magnesia product use: the product is used for magnesia brick, magnesia alumina brick, magnesia chrome brick, gunning material, castable, dry material, coating material, furnace filling material, asphalt, casting, fire protection and thermal insulation materials, flux auxiliary materials, Electrical steelmaking furnaces, heating furnaces, rotary furnaces, steelmaking, electric furnace bottoms and ramming furnace linings.

Large crystal fused magnesia products are mainly made of 0-3 particles of magnesia with a content of more than 90%, which are melted in an electric arc furnace. The product has high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulating material, and is also an important material for making high-grade magnesia bricks, magnesia-carbon bricks and unshaped refractories. raw material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc.

Large crystal fused magnesia product features: high purity, large melting crystal grains, high point structure, dense structure; good thermal shock stability; good high temperature flexural strength; good slag resistance and corrosion resistance; thermal conductivity Strong performance and high insulation.

Product use of large crystal fused magnesia: large crystal fused magnesia is used as a refractory lining for steelmaking furnaces, and is a high-quality and high-grade basic refractory raw material for making refractory bricks and unshaped refractories; it can also be used as a filler for making Thermocouples and thermal insulation materials (household appliances, etc.); also used in ceramic raw materials and sintering aids, as well as metallurgy, building materials, chemicals, national defense, medical equipment, etc.
