摘　　要：在离心浇铸金属凝固过程中，采用动态效应的方法对以达到细化晶粒的目的。本文研究了在电渣离心浇涛耐热钢炉管金属凝固过程中，采用动态效应后凝固组织的特征，并进一步探讨了动态效应作用的机理。A method of dynamic action was used during the solidification of the alloy in centrifugal casting. Thus ,the structure of the alloy was fined. In this paper ,the solidification structure of heat resisting alloy cast with dynamic action during centrifugal electroslag casting is studied ,and the mechanism of dynamic action is investigated.
