Abstract:

The production process of iron magnesium dolomite is simple.Iron magnesium dolomite has two high-melting-points solid phases—solid solution periclase(MgOss)and free clacium oxide(fCaO),so it has the characteristics of MgO-CaO refractories.With excellent comprehensive performance,the iron magnesium dolomite syntheticsand has high durability in application of dry play material,gun-mix refractory,coating and insulation castable refractory furnace charge.
