Abstract:The slag corrosion on refractories could be effectively inhibited as a consequence of less solubility of Cr2O3 component of Crcontaining refractories in molten slag and Cr2O3 saturation in molten slag with a small amount of Cr2O3 solubility. Under conditions of metallurgy, Cr2O3 reached equilibrium with MgO, Al2O3, ZrO2, SiO2 oxide components without low molten phase, so a number of Crcontaining refractories with good properties were producted. At oxidizing atmosphere, Cr6+ could be formed via reaction of Cr2O3 with CaO, innocent treatment of Cr6+ were attained by heat treatment in reducing atmosphere.
