 Dead burned magnesite is selected from natural magnesite, it is produced by mine selecting, purifying, calcining in shaft kilns. It is an ideal material for unshaped refectory material, the final products are used in opening hearth furnace, electric furnace bottom furnace¹s lining tamping.
DBM-90 MgO≥90 SiO2≤4.5 CaO≤1.6 L.O.I.≤0.3 B.D 3.18 (g/cm3)
DBM-91 MgO≥91 SiO2≤4.0 CaO≤1.6 L.O.I.≤0.3 B.D 3.20 (g/cm3)
DBM-92 MgO≥92 SiO2≤3.5 CaO≤1.6 L.O.I.≤0.3 B.D 3.16 (g/cm3)
Dead burned magnesite ( middle grade ) is made from sorted natural raw magnesite through sintering in high temperature shaft kilns. They are ideal materials for making monolithic refractories. Their finished products are also used for making the bottoms or lining of open-hearth furnace and electric arc furnace.
DBM-94 MgO≥94 SiO2≤2.5 CaO≤1.6 L.O.I.≤0.3 B.D 3.20 (g/cm3)
DBM-95 MgO≥95 SiO2≤2.0 CaO≤1.6 L.O.I.≤0.3 B.D 3.20 (g/cm3)
Dead burned magnesite ( high grade ) is made from sorted super grade natural magnesite through sections including float concentration, calcination, fine granding, high pressure briqueting and ultra high temperature sintering in heavy oil shaft kilns. They are good quality materials for making magnesia bricks and monolithic refractories.
