高(gao)(gao)鋁耐火(huo)磚的重(zhong)要工作性(xing)(xing)質之(zhi)一是在高(gao)(gao)溫(wen)下的結構強度(du)(du),這一特(te)性(xing)(xing)通常用荷重(zhong)軟化變形溫(wen)度(du)(du)來評定(ding)。也測定(ding)其高(gao)(gao)溫(wen)蠕(ru)變性(xing)(xing)來反映(ying)其高(gao)(gao)溫(wen)結構強度(du)(du)。試驗(yan)結果表明,荷重(zhong)軟化溫(wen)度(du)(du)隨Al2O3含量的增加而提(ti)高(gao)(gao)。
