摘　　要：利用模数法对发热保温冒口在铸钢件上的设计及应用进行了总结。与一般保温冒口相比，发热保温冒口补缩效果更好，其补缩效率平均提高8．4％，工艺出品率平均提高11．6％，有利于改善铸件品质，降低能耗，具有显著的社会和经济效益。The design and application for exothermic and insulating risers in steel castings with moduli calculation method were summarized. Compared with common insulating risers, the exothermic and insulating risers have better feeding effects, and the feeding efficiency and the process product rate increased by 8.4% and 11.6% respectively. It＇s helpful to improve the casting quality and reduce energy consumption, which has significant social and economic benefits.
