摘　　要：以棕刚玉（w（Al2O3）≥95．00％，粒度8～1mm，≤1mm），SiC（w（SiC）≥90．00％，粒度≤0．088mm），铝酸盐水泥，α—Al2O3微粉，SiO2微粉，高温沥青等为原料，研究了高铝粉煤灰加入量（质量分数，下同）分别为0.3％、6％、9％和12％时对Al2O3-SiC—C质浇注料物理性能和抗渣性能的影响。结果表明：随着高铝粉煤灰加入量的增加并达到9％时，Al2O3-SiC—C质浇注料的线变化率略有增大，抗渣性能与未添加粉煤灰的浇注料的相当；当高铝粉煤灰添加量增加并达到12％时，试样的抗高炉渣侵蚀的能力开始较明显下降。Al2O3-SiC-C catables were prepared using brown corundum（Al2O3≥95%,particle size8-1mm,≤1mm）,SiC（SiC≥90.00%,≤0.088mm）,aluminate calcium cement ,α-Al2O3 microfines,microsilica and pitch as starting materials,The effects of high aluming fly ash additions of 0.3%,6%,9%and12%（mass.%）respectively on cold physical properties and slag resistance of the Al2O3-SiC-Ccastables were studied.The results showed that the additions of 0-9% high alumina fly ash did not affect the slag resistance evidently,As the addition of high alumina fly ash reached 12%,the slag resistance of the specimen began to decline.
