  • the method according to the invention can be carried out advantageously if the acceleration in the setting direction, a hydraulic pressure or the setting force of a hydraulic actuator of the roller setting is used as a permanently measured variable.
  • Occurring vibrations are advantageously detected particularly quickly or suppressed in a particularly rapid manner when a permanently measured variable with a sampling time ⁇ 1 ms, preferably ⁇ 0.2 ms, a controller is supplied.
  • a further advantageous embodiment of the method is that the difference of the accelerations between the value on the piston rod and the value on the cylinder housing of a hydraulic actuator of the roller adjustment is used as a permanently measured variable.
  • a permanently measured variable is filtered by means of one or more bandpass filters, preferably by bandpass filters higher than the second order.
  • the controller determines the manipulated variable, taking into account a mathematical control law and a submodel, which characterizes the system state or the system behavior and preferably contains a hydraulic and / or mechanical and / or rolling force model.
  • the manipulated variable of the controller for suppressing vibrations of another manipulated variable, such as a roll gap control, additively superimposed and optionally supplied to a electro-hydraulic actuator after a phase change and / or a non-linear compensation.
  • the efficiency of the method according to the invention can be further increased if the supply pressure and / or the control pressure and / or the tank pressure at the electro-hydraulic actuator is stabilized by means of hydraulic accumulators.
  • the response time of the actuator is shortened or achieved a uniform response of the actuator largely independent of transient pressure fluctuations.
  • the electro-hydraulic actuator has a nominal flow rate ⁇ 100 l / min, preferably ⁇ 200 l / min. This makes it possible to provide with an actuator and high flow rates for controlling one or more actuators of the roller adjustment. As noted above, the nominal flow rate is determined at a pressure drop of 70 bar.
  • the size of the electrohydraulic actuator is selected via the inequality Q Nominal ⁇ 1592 * V Zyl , wherein the cylinder volume in m 3 is to be used in this numerical equation and the nominal volume flow Q Nenn results in l / min.

  • a measuring device is designed as an acceleration, pressure or force sensor.
  • the measuring devices are connected to the digital controller, for example, via cable or fieldbus.
  • An advantageous measuring device can be achieved if a measuring device has two acceleration sensors, wherein a sensor with the piston rod and a sensor with the cylinder housing of a hydraulic cylinder of the roller adjustment is connected. It is advantageous that the measuring axis of an acceleration sensor is arranged parallel to the Anstellides a hydraulic cylinder of the roll adjustment.
  • a further improvement of the dynamic properties of the device according to the invention can be achieved if a supply line and / or a control line and / or a tank line to the hydraulic valve has a hydraulic accumulator for pressure stabilization.
  • the hydraulic valve has a nominal flow rate ⁇ 100 l / min, preferably ⁇ 200 l / min.
  • the electrohydraulic actuator has a nominal flow rate of Q nominal ⁇ 1592 * V cyl , again using the cylinder volume V Zyl in m 3 and the nominal flow Q nominal in l / min.
  • Particularly advantageous dynamic properties of the device can be achieved if a hydraulic valve with a hydraulic cylinder of the roll adjustment forms an assembly or the hydraulic valve is in the immediate vicinity of the hydraulic cylinder.
  • Fig. 1 shows the basic structure of a controlled system for the suppression of vibrations.
  • a measured variable 2 Via an acceleration sensor 1, which is in communication with a roll of a roll stand 12, a measured variable 2 is fed to a bandpass filter 3, which is designed as a fourth order bandpass, which corresponds to the frequency component of the measured variable relevant for chatter oscillations, ie. of the acceleration signal, a controller 4 feeds.
  • This controller 4 comprising a control algorithm and the plant state characterizing partial models, calculated in real time, taking into account the filtered measured variable 2 and a target size 5 at least one variable-time manipulated variable 6, which is a lead / lag member 7 and subsequently fed to a non-linear compensation element 8 ,
  • a lead / lag member 7 By a lead / lag member 7, the phase of a signal, in the specific case of the Manipulated variable 6, to be changed.
  • Such a change in the phase position is therefore particularly advantageous because it is possible to assume a substantially constant chatter frequency in a particular rolling mill, and it is possible to make targeted use of this knowledge to increase the power of the vibration suppression.
  • the resulting volumetric flow 10 is subsequently fed to at least one actuator designed as a hydraulic cylinder 11, which in turn exerts forces on a roller of the roller set.
  • This makes it possible, first, to selectively extract energy from a disturbance variable 13 and, secondly, to selectively influence the attenuation of the overall system. Both measures have an advantageous effect on the suppression of third octave oscillations and cause thereby the quality of the rolling stock and / or the production capacity of the rolling mill can be increased.
  • a rolling mill 12 of a rolling mill is shown.
  • a controller 4 is connected to a designed as a servo valve hydraulic valve 9.
