What are the specifications of reburning magnesia?

The main specifications of the calcined magnesia are 0 mm - 0.5 mm; 0mm-1mm； 1mm-3mm； 3mm-5mm； 5mm-10mm； 10mm-30mm； 50mm-200mm； 200mm-500mm； The calcined magnesia product is mainly made of high content magnesite ore calcined in iron sheet shaft kiln. It is an ideal raw material for producing unshaped refractories. All kinds of refractories produced with it are mainly used in steel industry, glass, cement and non-ferrous metallurgy industries. Because of its good high temperature bending strength, slag resistance and corrosion resistance, reburning magnesia can improve the service life of steel furnace lining, so it is widely used in open hearth furnace, electric furnace bottom and ramming furnace lining. The lining refractory of the steelmaking furnace is also a high-quality ideal material for manufacturing unshaped refractory bricks.

It is only necessary to know the production process to distinguish the reburning magnesium oxide. The production equipment used for the reburning of magnesium oxide is the iron sheet shaft kiln, which uses 46% magnesite to be calcined at 1600 ℃ - 1800 ℃ in the iron sheet shaft kiln. In this case, it can be judged that it is re burned magnesia. The basic main models of re burned magnesia have 80% content, 85% content and 90% content. The main color of re burned magnesia is reddish brown. The products of re burned magnesia are widely used in magnesia bricks, magnesia aluminum bricks, magnesia chrome bricks, gunning materials, pouring materials, dry materials, coating materials, furnace repair materials, asphalt, casting, fire protection and insulation materials, flux accessories, electric steelmaking furnaces, heating furnaces, rotary furnaces Steel making, electric furnace bottom and ramming furnace lining.

The calcined magnesia is mainly made of 46% magnesite ore, which is calcined at 1600 ℃ - 1800 ℃ through a layer of coal and a layer of magnesite in the iron sheet kiln. The production process is that two tons of ore produce one ton of calcined magnesia, which is divided into three grades; 1、 The calcined magnesia in front of the kiln is mainly red brown. The calcined magnesia is characterized by high fire resistance.

Purposes of reburning 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 protection and insulation materials, flux accessories, electrical steelmaking furnaces, heating furnaces, rotary furnaces, steelmaking, electric furnace bottoms and ramming furnace linings.
