Abstract: This paper compares the thermal shock damage resistance and the slag corrosion resistance of a high-alumina and an alumina-containing andalusite refractory castable. Thermal shock damage resistance was analyzed through thermal cycling and thermal shock damage resistance parameters. Thermal shock cycling damage was analyzed using the dynamic modulus of elasticity (E) and the modulus of rupture (MOR) before and after the thermal shock cycles. The alumina-containing andalusite castable showed superior thermal shock damage resistance in both parameters. The high-alumina castable showed a higher resistance to slag corrosion. These results were linked to material selection for specific industry applications.
