Abstract

The rolling mill has a rolling stand provided with two rolls, which cooperatively roll two tube blanks. A mandrel rod (5) is arranged inside the tube blanks during rolling process. The rolls are in an operating position. The mandrel rod defines a wall thickness of a tube to be rolled. The mandrel rod has a shape e.g. oval shape, which deviates from a circular shape in a cross-section perpendicular to its longitudinal axis. A rotational unit is integrated in the mandrel rod and is arranged in movable manner.
