摘　　要：通过引入变形系数的概念,建立了三维变形时高向、宽向应力间关系,并以此为基础推导了全主动四辊组合孔型轧制时的单位压力和轧制力的差分公式。轧制力计算结果与试验结果吻合较好。By introducing the concept of deformation factor, the relationship between height and wedth direction stresses in three dimensional deformation has been built up, Based on the relationship, differential formulas of the specific pressure and rolling rerco have been deduced for four-roll (all driven) pass rolling and the calculated results agreed with the experimental data.
