The characteristics of metal flow in different periods were analyzed, and the curve of variety in non-round area at different crosssections of the rolled piece, the curve of variety in bulge volume and the curve of variety in non-column volume were obtained. On this base the method of tool design is worked out and validated by experiment. 关 键 词：金属形变 对角轧制 阶梯轴 非容柱积 膨胀体积 有限元模型
