摘　　要：介绍了新型蠕化剂的研制过程。研究得出用RE-Cu-Zn-Mg-Si-Fe合金(wRE=15%～22%),w(Cu)15%～22%,w(Zn)2.5%～4%,w(Mg)0～3%,w(Si)29%～32%,Fe余量)作蠕化剂,其适宜加入量范围宽,便于蠕铁生产的稳定。The development process of new type vermicularizing alloys was described. As the result of the investigation, a kind of Re-Cu-Zn-Mg-Si-Fe vermicularizing alloy with composition of ω（RE）15%-22%, ω（Cu）15%-22%, ω（Zn）2.5%-4%, ω（Mg）0-3%, ω（Si）29%-32% was obtained. This kind of vermicularizing alloy has the advantage that its proper addition range is wide, so it is beneficial to obtain stable vermicularity.
