摘　　要：通过对高炉入炉原料和支出物料铅元素平衡计算,采用扫描电镜和能谱分析仪对高炉风口部位滴出的金属液进行系统的取样分析研究,分析了高炉生产中铅的行为规律。针对铅元素的循环富集给高炉冶炼带来的不利影响,提出了减少入炉原料的铅含量、提高高炉排铅率、在高炉内设置排铅孔的抑制措施。Through balance calculation of lead in the raw material of BF charging and spending material, using scanning electron microscopy（sem）and energy spectrum analyzer for the BF tuyere area drops of liquid metal in the sample analysis, the behavior of lead in BF are analyzed. For enrichment of the cycle of lead to the adverse effects of blast furnace smelting, some measures included reducing lead content charged raw materials, increasing the exhausting rate of lead and installing exhausting lead hole in BF were put out.
