ABSTRACT:
In a four-high rolling mill stand where the work rolls are offset from the perpendicular axial plane of the back-up rolls, they are supported on one side by intermediate rolls and support rollers, and on the other side by hydraulic piston/cylinder units. The work roll bearings are attached to the piston/cylinder units through a sliding guide arrangement, so that they can be slid up and down, from side to side, and the work rolls can also be moved towards and away from the roll gap by actuation of the piston/cylinder units.
