摘　　要：研究了水泥加入量对铝铬尖晶石刚玉浇注料体积密度、显气孔率、抗折强度、耐压强度、抗渣和抗热震性的影响。实验表明:(1)随着水泥加入量的不断增加,110℃×24 h和1 200℃×3 h条件下样样抗折强度和耐压强度不断增加,1 550℃×3 h条件下试样抗折强度和耐压强度先增加后减小。(2)随着水泥加入量的不断增加,各温度下气孔率逐渐增大,体积密度逐渐减小。(3)随着水泥加入量的不断增加,抗热震性逐渐增强。(4)随着水泥加入量的不断增加,抗渣性能逐渐降低。The effect of the addition of pure calcium-aluminate cement on bulk density、apparent porosity、rupture strength、compressive strength、resistance of slag and thermal shock resistance of aluminum-chromium spinel corundum castables are studied in this chapter.The re?sults show that:as the addition of calcium-aluminate cement increasing,1)the breaking strength and compressive strength increase after heat treating at 110℃for 24 h and 1200℃for 3 h;the breaking strength and compressive strength first increase and then decrease after heat treat?ing at 1550℃for 3h;2)the apparent porosity increases and the bulk density decreases;3)the thermal shock resistance increases;4)the resis?tance of slag decreases.
