摘　　要：以钢液中Si元素还原Cr2O3的冶金热力学为基础,分析还原Si含量、还原温度、炉渣碱度对AOD还原后炉渣中Cr2O3含量的影响规律。试验结果表明:随着还原Si含量和还原温度的提高,炉渣中Cr2O3含量依次减小;炉渣碱度为1.8时,AOD还原后炉渣中Cr2O3含量低。According to the metallurgical thermodynamics of Cr203 reduction by Si in the liquid steel, the effect of the Si content, the temperature at the stage of AOD reduction and the basicity of slag were analyzed. The results show that theCr203content of slag after AOD reduc- tion decreases with the Si content and the increasing temperature; the Cr203content of slag after AOD reduction is lower under the basicity of slag is 1.8.
