Dead Burned Magnesia (DBM)

85%-92% Dead burned magnesiais mainly made of natural magnesite ore with 46% content, which is calcined by high temperature kiln at about 1400℃-1800℃. Application: Dead burned magnesia is mainly used as raw material for making magnesia bricks and producing amorphous refractory materials. The finished products are used in steel making, electric furnace bottom and ramming furnace. The main varieties of dead burned magnesia have 85%-92% content, these varieties are mainly selected 46.5% to magnesite, sintered kiln calcination heating to 1400-1800 ℃ Mg(CO3) completely decomposed, generating magnesite, become hard reddish-brown dead burned magnesium, it has a high refractorability. Dead burned magnesia is mainly used for magnesia brick, steelmaking, electric furnace bottom and ramming furnace lining.
