Roll stand, rolling system and method for actively damping vibrations in a roll stand

A rolling system (1) for rolling, preferably cold-rolling, metal objects, comprising at least one roll stand (2) and at least one system (3) for actively damping vibrations in the roll stand (2), wherein the roll stand (2) comprises at least one actuator (16) which can be actuated for actively damping vibrations in the roll stand (2), and at least one back-up roll (10) for supporting a working roll (5) and/or intermediate roll of the roll stand (2), which can be adjusted exclusively via a readjusting device for pass line adjustment (13) of the roll stand (2) or which is non-adjustable, wherein the supporting roll (10) is guided at the ends via a respective bearing unit (11) on a rack (8) of the roll stand (2), and is characterized in that the supporting roll (10) is supported on the actuator (16) via at least one bearing unit (11) and that the actuator (16) is supported on a section (17) of the rack (8) directly via at least one component (14) of the readjustment device (13) or indirectly, wherein at least one vibration sensor (18) is arranged on the rack (8) for acquiring the vibrations of the roll stand (2), and

• wherein the system (3) comprises at least one control electronics (20) which is connected by signal technology to the vibration sensor (18) and to the actuator (16), by means of which vibration signals generated by the vibration sensor (18) can be evaluated for the generation of control signals, and which is set up to actuate the actuator (16) for the introduction of counter-vibrations into the roll stand (2) by means of the respective control signals.
