刚玉-尖晶石浇注料基质部分最佳配比研究

Study on the best ratio of the matrix composition of the corundum-spinel castable

以致密电熔刚玉为骨料，研究了刚玉-尖晶石浇注料基质中电熔刚玉、电熔镁砂和烧结尖晶石细粉的配比关系，测试了材料的物理性能和抗渣侵蚀性能。结果表明：在电熔刚玉细粉与电熔镁砂细粉之比为72：28，尖晶石细粉加入量为15％时，材料具有合理的线变化率和良好的抗渣性能。

With dense fused corundum as agglometrates, the best ratio of the Powders of fused corundum, fused magnesia and sintered spinel in the matrix has been studied. The physical properties and the slag resistance of the specimens have been tested. The results show: the material has appropriate P. L. C. and better slag resistance when the ratio of fused corundum and fused magnesia is 72:28 and the spinel addition is 15%
