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.
Claims6
A multi-roll rolling mill stand comprising:
- a housing;
- two driven back-up rolls;
- two work rolls each driven by frictional engagement with a respective one of the back-up rolls and which are offset from the perpendicular axial plane of the back-up rolls;
- a roll gap formed between the work rolls;
- bearings mounting the ends of the work rolls;
- intermediate rolls and support rollers supporting the work rolls on one side of the work roll gap;
- thrust devices supporting the work roll bearings on the other side of the roll gap;
- and
- a sliding guide arrangement by means of which the bearings are connected to the thrust devices so that the work roll bearings can slide both vertically relative to the back-up rolls and horizontally parallel to the back-up roll axes and so that the work rolls can be moved horizontally by the thrust devices towards and away from the intermediate rolls.
