Abstract：

Through the study of the process of cross wedge rolling step-axis with the help of FEM software ANSYS-DYNA, and on the basis of analysis of circulation deformation character of mid-radius points of the billet, the alternating times of the center cross section of workpiece has been obtained. Through the comparison between typical rolling experiment models and results of analysis of FEM software, the effect of alternating times on the internal rarefaction is known, which provides the basis for researching rarefaction mechanism of cross wedge rolling.
