Abstract

The paper describes the aspects of improving the pilger tube cold rolling technology in modern rolling mills. A review of the current effective methods for calculating the calibration of the working tools (dies, mandrel) of the cold pilger tube rolling mill (HPT) is given. A combined procedure for calculating the rolling force and power parameters along the length of the deformation zone is proposed, which accounts for the dies and mandrel calibration, elastic flattening of the rolls, contact friction, and tension of the work-piece.
