On the basis of Fe-C binary model, the modification was made to draw into the effects of other alloying elements on the solidification process and the driving force for interdendritic fluid flow. Thus the segregation behavior of carbon was expected to be reflected more comprehensively by the model. In addition, the problems such as peritectic reaction, non-constant partition ratio were dealt with. Key words:  steel ingot      macrosegregation      numerical simulation      alloy solidification      Received:  18 May 1997      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1997/V33/I5/461 1 Bennon W D,Incropera F P.Int J Heat Mass Transfer,1987;30:21 2 Voller V R,Prakash C.Int J Heat Mass Transfer,1987;30:1709 3 Beckerman C,Viskanta R.
