Abstract

A smoothing rolling mill having identical frusto-conical smoothing rollers ounted on axes inclined to the axis of displacement of a tube blank passing between the rollers. The axes of the rollers converge in the direction of displacement of the tube blank. The tube blank is rotated and displaced axially between the smoothing rollers in a conventional manner. If desired, the shafts which mount the rollers for rotation can be pre-loaded with respect to the tube blank.
