摘　　要：为了提高含钛炉渣的流动性能以及促进渣铁更有效地分离,并替代对环境污染较大的CaF2资源,运用扫描电镜、黏度仪等设备在1340~1475℃温度范围内研究了B2O3及CaF2对含钛炉渣表观黏度的影响规律。结果表明,B2O3具有和CaF2相似的作用效果,均能够降低含钛炉渣的表观黏度。当B203及CaF2的添加量为1%时,B2O3与CaF2的替代比为1:1;随着渣中B2O3添加量从0增加到3%,钙钛矿质量分数逐渐降低,富钛深绿辉石随之增加,而Ti(C,N)质量分数几乎不变。For improving the low flowability,promoting the separation of the high Ti-bearing blast fur-nace slag and the hot metal and replacing the CaF2 which would pollute the environment,the influence of B203 and CaF2 on the apparent viscosity of the slag were investigated by SEM,viscometer,et al un-der the tmeperature from 1340 to 1475C.The results showed that B2O3 had a similar effect as the CaF2 and can decrease the apparent viscosity of the high Ti-bearing blast fumace slag.When the a-mount of B2O3 and CaFz was equal to 1%and the ratio of B2O3 and CaFz was1:1,with the B2O3 in-creasing from 0 to 3%,the perovskite content gradually decreased,and the titaniferous augite in-creased,whilet he Ti(C,N)was almost constant.
