What are the specifications of dead burned magnesia?

The main specifications of dead burned magnesia are 0mm-0.5mm; 0mm-1mm; 1mm-3mm; 3mm-5mm; 5mm-10mm; 10mm-30mm; 50mm-200mm; 200mm-500mm; Magnesite ore is calcined in iron shaft kiln. Dead-burned magnesia is an ideal raw material for the production of unshaped refractory materials. Various refractory materials produced from it are mainly used in the iron and steel industry, as well as in the glass, cement, and non-ferrous metallurgical industries. Because dead burnt magnesia has good high temperature flexural strength, slag resistance and corrosion resistance, it can improve the service life of steelmaking furnace lining, so it is widely used in steelmaking open hearth, electric furnace bottom and ramming furnace lining. The lining refractory material of steelmaking furnace is also an ideal high-quality material for making unshaped refractory materials of refractory bricks. Lightly burnt powder

To distinguish dead-burned magnesia, you only need to know its production process. The production equipment used for dead-burned magnesia is iron shaft kiln, and 46% magnesia is calcined in iron shaft kiln at 1600℃-1800℃. In this case, it can be judged that it is dead-burned magnesium oxide. The main types of dead-burned magnesium oxide have 80% content, 85% content and 90% content. The main color of dead-burned magnesium oxide is reddish brown. Widely used in magnesia bricks, magnesia alumina bricks, magnesia chrome bricks, gunning materials, castables, dry materials, smearing materials, furnace filling materials, asphalt, casting, fire protection and thermal insulation materials, flux accessories, electrical steelmaking furnaces, heating furnaces , rotary furnace, steelmaking, electric furnace bottom and ramming furnace lining.

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.

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.
