摘　　要：基于现场精炼渣成分,通过高温渣钢平衡试验,研究了炉渣的终点化学成分与形貌、钢中总氧含量的变化,分析了炉渣碱度和Al_(2)O_(3)含量对夹杂物成分的影响,为精炼渣系优化和现场操作提供依据。Based on the composition of on-site refined slag,the changes of the chemical composition and morphology of the end point of the slag and the total oxygen content in the steel were studied through the high-temperature slag steel balance experiment,and the effects of slag alkalinity and Al_(2)O_(3) content on the inclusion composition were analyzed,which provided a basis for the optimization of the refining slag system and the on-site operation.

关 键 词：精炼渣 钢水洁净度 炉渣碱度 夹杂物 Al_(2)O_(3)含量
