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.
