ABSTRACT:
To fix the relative axial position of a roll of a rolling mill and particularly with rolls of an unsymmetrical shape to improve the maintenance of tolerances for flange thicknesses of rolled sections at least one roll is provided with a double acting hydraulic cylinder for axial positioning by which the axial position is held fixed by an actual value-set value comparison by a control device. The actual value measurement of the axial position during a pass in which the rolls have changing axial forces should occur as close as possible to the rolled section for elimination of the position shifts due to compressibility or flexibility of components.
