Abstract

A new generalized method for calculating the rolling radius is developed. It is based on an analysis of the real shape of the neutral line in the deformation zone provided that the workpiece in equilibrium under the forces applied to it. It is established that there can be four characteristic positions of the neutral line within the contact surface between the roll and the workpiece. The particular case where the neutral line lies in a plane parallel to the rolling axis and the calculated rolling radius is effective is considered. The actual and effective rolling radii in the case of plugless rolling of pipes in oval roll passes are calculated and compared. A best-fit formula for correcting the calculated values of the effective rolling radius is obtained.
