PURPOSE:To obtain the subject refractory brick having improved corrosion resistance and thermal shock resistance by mixing a specific high-alumina raw material, a chromia raw material and an alumina-zirconia raw material at specific ratios. CONSTITUTION:The alumina-chromia-zirconia refractory brick is composed of 80-90wt.% of a high-alumina raw material having an Al2O3 content of >=80wt.%, 5-15wt.% of a chromia raw material having a Cr2O3 content of >=90wt.% and 3-10wt.% of an alumina-zirconia raw material having a ZrO2 content of 15-40wt.%. |
