摘　　要：保持α-Al2O3微粉与硅微粉(两者的比例为2:1)和纯铝酸钙水泥的总量为10%,逐步降低纯铝酸钙水泥的用量(由5%降至1%,相应地微粉总量由5%增大到9%),并在不同温度下对试样进行热处理(烧结),系统地研究了纯铝酸钙水泥用量和热处理(烧结)温度对低水泥和超低水泥耐火浇注料线变化率、体积密度、常温抗折/耐压强度等性能的影响,并对实验结果进行了详细分析与讨论。It is researched systematically that the effect of CA-70 cement and the heat treatment temperature on the liner changing, bulk density, crushing strength and modulus of rupture of low and ultralow cement refactoty castables in this paper by keeping the total amount of SiO2 and α-Al2O3 fine-powder （the ratio of SiO2 to α-Al2O3 is 2：1）and CA-70 cement to be constant （10%）,lowering gradually the amount of CA-70 cement from 5% to l% （correspondingly the amount of fine-powders increasing form 5% to 9% ）and sintering the specimens at various temperature. The test result is analyed and discussed in detail.
