Abstract
A combined work roll crossing, offsetting, bending and work roll axial shifting system for a rolling mill having a housing member on each side and at each end of each work roll, Mae West blocks mounted on the housing members, roll chocks surrounding the ends of the work rolls, a pusher member mounted on each of the Mae West blocks and movable into and out of contact with the corresponding roll chock, a first hydraulic piston/assembly mounted on each of the housing posts and connected to the corresponding pusher member to move the pusher member into contact with a corresponding chock and to effect crossing or offsetting of a corresponding work roll, a pair of roll bending second piston/cylinder assemblies mounted in each Mae West block such that the pistons contact the corresponding roll chocks to move the chocks toward or away from the corresponding work roll when the second cylinders are actuated, a third set of cylinder/piston assemblies mounted in the Mae West blocks for balancing the backup rolls, and a fourth set of piston/cylinder assemblies mounted on the housing, parallel to the work roll axis, and the pistons thereof being connected to the pusher members to shift the pushe…
