摘　　要：针对炼钢终脱氧工艺长期以来用铝块作终脱氧剂,存在回收率低、成分波动范围大的弊端,根据终点碳和终点温度的碳氧平衡计算公式导出初始含氧量,并由Al-O平衡曲线导出目标座包铝含量的钢芯铝用量。将理论计算应用到了现场的终脱氧工艺中,对炼钢终脱氧工艺优化有指导作用。Since aluminum block used as end deoxidation agent for a long time the steel - making end deoxidation process has defects of low recovery ratio and large composition fluctuation. It is researched how to optimize the process： derive preliminary oxygen content based on carbon - oxygen balance formula of end carbon and end temperature, derive steel cored aluminum consumption for target ladle aluminum content with A1 -0 balance curve. The theoretical calculation is used in site end deoxidation process and plays a guide role.
