Abstract　 Based on the statistical analysis of 95 heats | about 14,000 t metal production data of EAF steelmaking at Tianjin Steel Pipe Corporation, the influence of charging DRI in EAF on metal yield and steel composition has been studied. The results show that with charging DRI the Cu, Pb Sn As and N content decreased appreciably.Material Index　EAF, Steelmaking, DRI
　　天津钢管公司是生产大口径石油用无缝管的专业化电炉钢厂，对钢中金属残余元素(Ni,Cr,Cu和五害元素Pb,Sn,As,Sb,Bi)的含量有严格的限制。这些金属残余元素来自废钢而在冶炼过程中无法有效去除，国际上通用的对策是在入炉原料中配入一定比例的“纯净的”含铁原料(直接还原铁)代替“脏”的废钢，即采取稀释的办法使金属残余元素的含量降低。　　天津钢管公司在厂房布置和装备各方面
