摘　　要：以山西矾土为主要原料,铝酸钙水泥为结合剂,三聚磷酸钠为减水剂。通过不同的水泥加入量(3%、5%、7%、9%、11%),在110℃×24 h、1100℃×3 h和1450℃×3 h烧成。性能检测表明:在水泥加入量为5%的时候,耐火浇注料的体积密度较高,耐压强度好,线变化率小,浇注料的各项性能达到最佳。In this experiment, bauxite chamotte is used as main raw nmterial,high alumina cement as bonder, sodium tripolypho sphate as water reducing agent. With the different amount of cement （3 v/o ,5 % ,7 % , 9 % , 11% ）, the cement castables are heated at 110 ℃ x 24 h, 1 100℃ x 3 h and 1 450 ℃ x 3 h. The experiment result shows that when the cement addition is 5% , the bulk density of castables is higher, the CCS is best, and the linear changing rate is the lower, properties of all kinds of high - alumina castables are the best.
