摘要： 以河北钢铁集团承德钢铁集团有限公司现场高炉渣为基准，用化学纯试剂配制渣样，考察了添加剂对中钛炉渣粘度、熔化性温度的影响. 结果表明，炉渣碱度为1.12, CaF2含量为0.5%~2%, Fe2O3含量约为5%, Al2O3含量约为13.75%, MgO含量约为13.95%, MnO含量约为5%(w)时，有利于降低炉渣粘度和熔化性温度；添加Ce2O3使炉渣熔化性温度和粘度升高，不利于生产.

Abstract: Based on the blast furnace slag from Chengde Iron and Steel Company in Hebei Iron and Steel Group, the slag samples were prepared with chemical reagents, and the effects of additives on the viscosity and melting temperature of medium-titanium blast furnace slag investigated. The results show that when the basicity of slag is 1.12, the content of CaF2 0.5%~2%, Fe2O3 about 5%, Al2O3 13.75%, MgO 13.95% and MnO 5%(w), it is conducive to improving the slag melting temperature and viscosity. Ce2O3 added to the slag makes melting temperature and viscosity increase, which is not conducive to the production.

Key words: medium-titanium blast furnace slag, additive, viscosity, melting temperature
