DBM(MgO<70%)

TR brand high-iron and calcium magnesite use light burned magnesia as main raw material, together with calcium oxide, iron powder and other additives, by two-step synthesis to form magnesia, with a stable composition, and the specifications also can be changed per coustomers requirement. Product feature: high temperature performance and high-density, strong anti-permeability ability and easy to rapid sintering, very thin sintered layer,good thermal shock stability, strong slag-resistance, long service life and so on. Function Apply to the construction of bottom and wall of all kinds steel making electric arc furnace and ferroalloy smelting furnace for hot charging of hot metal and second hand steel Specifications: index Chemical composition /% Physical composition item MgO Al2O3 SiO2 CaO Fe2O3 BD/g/cm3 size MTS-68Aa 68-80 ≤2.5 ≤9.0 ≥10.0 ≥3.25 0-30 MTS-68Ab 68-80 ≤3.0 ≥10.0 ≥3.25 0-30 MTS-68Ac 68-80 ≤5.0 ≥10.0 ≥3.25 0-30 MCa-32 63-65 ≤1.0 31-33 ≤3.0 ≥3.25 0-30 MCa-25 72-74 ≤1.0 23-25 ≤1.0 ≥3.25 0-30
