Notes:
The temperature distribution of the permeable brick was modeled using CFX software. Theinfluence of magnesia and corundum on thermal shock resistance of non-cement bonded alumina-basedpermeable brick was investigated. The results indicated that, in the gas blow process, the hightemperature regions near the working face of the brick gradually expanded with the increase of the gasflow rate. Therefore the inner part of the brick had the complex and large change of thermal stress. Furtherexperiments demonstrated that thermal shock resistance of alumina-magnesia based castable refractorywas better than that of alumina-chrome based castable refractory. With the increase of magnesia amount,the alumina-magnesia based castable refractory had more cycles of heating and water-cooling. Whendifferent kinds of corundum were added in the raw materials, the sample with tabular corundum showedthe best thermal shock resistance, the one with white fused corundum performed worse and the one withfused dense corundum performed worst
