摘　　要：针对高铝矾土原料质量下降导致钢包铝镁浇注料使用寿命下降情况,对配方进行调整实验,结果表明:(1)适当增加了镁点,解决产品的高温收缩。(2)引入刚玉原料优化浇注料的基质组成,既降低了施工加水量,又减少了收缩,提高产品的耐高温性,使铝镁尖晶石浇注料具有优良的抗渣性和抗剥落性能。For high quality of bauxite raw material of aluminum-magnesium cause ladle castable life declines,the experiment was adjusted.The results show that：（1） An appropriate increase of magnesium can settle the temperature contraction.（2） The introduction of raw materials corundum not only the use of water,decreases the shrinkage and improve the property of high temperature-resisting.It also makes aluminum-magnesium spinel castables have excellent slag-resisting and anti-peeling performance.
