Pagsusuri ng slag corrosion resistance ng chrome corundum brick

The solubility of Cr2O3 in coal gasifier slag (SiO2-CaO series) and various glass melts is much lower than that of other oxide materials. Therefore, Cr2O3 or refractories containing Cr2O3 have good corrosion resistance to steel slag, non-ferrous smelting slag, coal gasification slag, oil gasification slag and various glass melts. The liquid phase viscosity of Cr2O3 melt or the reaction of Cr2O3 and slag is higher than that of other low melt materials, which prevents the slag from penetrating into the brick body along the capillary pores, and avoids the formation of a metamorphic layer and structural peeling.
