Abstract

The slag corrosion and penetration behaviors of MgAl₂O₄, MgAl₂O₄-ZrO₂, MgAl₂O₄-ZrO₂-CaO, Al₂O₃, and Al₂O₃-ZrO₂-SiC refractories were investigated using the static crucible method at 1873 K for 2 h. The above refractories all displayed excellent slag corrosion resistance, and their corrosion depth was less than 1.10 mm. Al₂O₃ material was hardly corroded by the molten slag, and its corrosion depth was only 0.05 mm. Their penetration depth ranged from 13.79 to 24.48 mm. Among them, Al₂O₃-ZrO₂-SiC refractories displayed good slag penetration resistance with a penetration depth of 13.79 mm.
