| 摘 要： | 超细粉结合超低水泥耐火浇注料，具有良好高温性能，成本较低，但抗热震性能不理想．莫来石结合锆刚玉浇注料含有较多ZrO2(30％以上)，耐高温抗热震，抗蚀性能优良，但其成本高，除特殊情况外，难于大批量推广应用，耐火浇注料(Al2O3)中引入少量ZrO2可以大幅度改善耐火浇注料抗热震性能，且成本增幅不大。

| Abstract: | Ultra-low cement refractory casting materials combined by superfine powder are provided with high temperature resistance capability and their cost are low, but their anti-hot shock capability are not ideal. Zir-corundum casting materials combined by mullite contain much more ZrO2(>30%), they are able to bear high temperature and anti-hot shock, and their anti-corrosion capability is choiceness, but their cost are high. The applications of the zir-corundum casting materials are difficult except under special circumferences. Adding a little of ZrO2 would improve the refractory casting materials anti-hot shock capability to a great extent and the increase of the cost is low. |
