摘　　要：以矾土为骨料,通过加入电熔镁砂优化配置制备铝质耐火浇注料试样。结果表明:随着电熔镁砂加入量增加,镁铝尖晶石的生成量增加;与加入电熔镁砂颗粒相比,加入电熔镁砂细粉的试样体积密度较大,显气孔率较小,强度较低;1 000℃时高温抗折强度均较高,1 200℃时高温强度因为产生液相降低,1 400℃时因产生大量液相而基本无高温强度;加入5%电熔镁砂粒度为1~0.2 mm的铝质浇注料抗渣渗透性最好。The aluminum refractory castable sam ples were prepared by adding fused magnesia to bauxite as aggregate. The results show that the amount of Mg-Al spinel increases with the addition of fused magnesia. Compared with fused magnesia particles, the sample with fused magnesia fine powder has higher volume density, smaller porosity and lower strength. High temperature flexural strength is higher at 1 000℃. At 1 200 ℃, the intensity at high temperature decreases due to the generation of liquid phase. At 1 400℃, there is no high temperature strength due to the generation of a large amount of liquid phase. The slag permeability of aluminum castable with 5% fused magnesia particle size of 1~0.2 mm is the best.
