Abstract
The apparatus for the counterbalancing and vertical bending of the work rolls of a four-high rolling mill stand (1) comprises respectively two dual-acting hydraulic adjusting cylinders (13) installed in the bottom work roll chocks (4) symmetrically to the roll axis plane (12--12). The adjusting piston (14) of the adjusting cylinders (13) serves for moving the piston rod (15) out of the bottom chock (4) and for moving the free end of the piston rod (15) into the top work roll chock (15) during rolling operation, and for moving the piston rod (15) into the bottom chock (4) for the separate dismounting of the work rolls (6, 7). During rolling operation, the extended piston rod (15) is connected, by means of a coupling device (16), with a shaft (22) supported in articulated fashion in the top chock (5).
