Definitions

  • the invention relates to a roll stand for rolling, preferably cold rolling, metal products, comprising at least two adjusting units, each arranged on a stand of the roll stand, for adjusting an upper work roll of the roll stand together with an upper back-up roll of the roll stand and for adjusting a height of a roll gap of the roll stand, at least an actuator which can be controlled for the active damping of vibrations in the roll stand, and at least one set of rolls that can only be adjusted via an adjustment device for passline adjustment of the roll stand or a non-adjustable set of rolls for supporting and / or intermediate roll of a work roll of the roll stand, with all of the rolls at each end via a bearing unit a stand of the roll stand is performed.
  • the invention further relates to a rolling plant for rolling, preferably cold rolling, metal objects, having at least one roll stand and at least one system for actively damping vibrations in the roll stand.
  • the invention also relates to a method for actively damping vibrations in a roll stand for rolling, preferably cold rolling, metal products, the vibrations in the roll stand being recorded and counter-vibrations being generated, the counter-vibrations being generated by means of at least one actuator.
  • 5th octave chatter vibrations are usually natural vibration forms of the set of rolls of a rolling stand in the frequency range between 500 Hz and 1000 Hz, which are caused by external excitations (so-called “forcing functions"), such as speed-proportional excitation frequencies from roller bearings or the rolls or gear mesh frequencies are excited by gear stages. These mostly cause surface and / or shape defects in the rolled metal product that are oriented transversely to the product or strip running direction.
  • the 3rd octave chatter oscillation is a self-excited oscillation form which can also lead to thickness errors oriented transversely to the product or strip running direction and consequently to strip tears at high amplitudes.
  • the instability arises here from the fact that a certain form of natural oscillation of the complete set of rolls in the roll stand is destabilized by a feedback system inherent in the rolling process.
  • the chatter-relevant natural vibration mode of the roll stand is usually that in which an upper and a lower set of rolls in the roll stand essentially vibrate against each other. As a result, there is a high energetic potential for the excitation of this form of oscillation from the roll gap.
  • the frequency of this natural oscillation form is usually between 80 Hz and 160 Hz.
  • the destabilizing feedback (positive feedback) is created by the rolling process itself, as changes in the inlet speed caused by changes in the outlet thickness cause fluctuations in the inlet tension due to the law of mass flow, which in turn affect the rolling force (so-called Tensile reaction) and thus in turn influence the outlet thickness.
  • the rolling speed at which the stability limit for the self-excited 3rd octave chatter oscillation is reached usually only increases by comparatively small amounts, for example 50 m / min - 200 m / min, can be increased. In many cases, the maximum possible system speed cannot be achieved with these approaches.
  • WO 2015/092775 A1 discloses another method for actively damping vibrations in a roll stand.
  • hydraulic actuators are used, which act to actively dampen vibrations on bearing units of rolls, over which the rolls are guided on a stand of the roll stand.
  • a piezoelectric injector is arranged, which is inserted directly into the pressure chamber of the hydraulic actuator. The damping effect is generated by high-pressure oil injection into the hydraulic actuating units.
  • WO 01/00346 A1 discloses a vibration damping device for use in a rolling mill.
  • the device comprises a body which is positionable for sliding movement in a housing located on or near a nib of the rolling mill. Furthermore, the device has damping means for providing vibration damping of a roller block (s) within the rolling mill.
  • the damping means is integral with the body and has a mass that is movable in the body.
  • EP 1 457 274 A2 discloses a method for avoiding vibrations, in particular 3rd and 5th octave vibrations, in a rolling mill with at least one roll stand with roll adjustment and at least one set of rolls. At least one permanently measured variable of the rolling mill is fed to a controller that includes a mathematical control law and partial models characterizing the system condition, with the help of this controller at least one time-variable manipulated variable determined in real time, fed to at least one actuator and at least one of the rollers through the actuator of the set of rolls and / or the rolling stock is acted upon, the controlled variables being kept at defined setpoints.
  • the EP 1 457 274 A2 is regarded as the closest prior art and shows the features of the preamble of claim 1.
  • EP 1 961 992 A2 discloses a device for active vibration damping of two counter-rotating rollers.
  • the device comprises at least one sensor for detecting the vibration on at least one roller, a controller for processing the vibration data recorded by the at least one sensor and for outputting a control signal based on this vibration data, and at least one actuator that controls at least one of the rollers based on the control signal acted upon by a force counteracting the vibration.
  • the actuator is arranged in such a way that it acts on the outer surface of the corresponding roller (s).
  • One object of the invention is to enable optimal active damping of vibrations in a roll stand with little structural effort.
  • a roll stand according to the invention for rolling, preferably cold rolling, metal products comprises at least two adjusting units, each arranged on a stand of the roll stand, for adjusting an upper work roll of the roll stand together with an upper back-up roll of the roll stand and for adjusting a height of a roll gap of the roll stand, at least one actuator, which can be controlled for the active damping of vibrations in the roll stand, and at least one support roll, which can be adjusted exclusively via a wedge adjustment of the roll stand or not, for supporting a work roll or intermediate roll of the roll stand.
  • the end of the support roll is guided via a bearing unit on a stand of the roll stand.
  • the actuator is arranged separately from the adjustment unit, the support roller is supported on the actuator via at least one bearing unit and the actuator is supported either indirectly via at least one adjustment device for passline setting, e.g. B. a wedge setting or directly on a section of the stand, so that the actuator is thus in the main force flow of the roll stand.
  • at least one adjustment device for passline setting e.g. B. a wedge setting or directly on a section of the stand, so that the actuator is thus in the main force flow of the roll stand.
  • the active damping makes it possible to reduce maintenance costs and intervals, as it reduces the effects of the above-mentioned external suggestions on the product quality.
  • the invention is a simple, inexpensive, easily integrated and retrofittable solution, in particular if the actuator is arranged at the installation site of a conventional load cell on the roll stand. There are then practically no structural changes to a roll stand required for the integration of the actuator.
  • the invention can therefore be implemented both in the course of retrofitting existing roll stands and in new roll stands.
  • the with EP 2 052 796 A1 proposed solution comparatively complex, expensive and maintenance-intensive.
  • the roll stand according to the invention can also have two or more corresponding actuators which can be controlled jointly or individually for the active damping of the vibrations in the roll stand.
  • the actuation of the actuator or the actuators can take place electrically, for example.
  • the back-up roll can either only be adjustable by means of an adjustment device for adjusting the pass line of the roll stand, or it cannot be adjusted.
  • the wedge adjustment is used to adjust the alignment of the back-up roll and the work roll supported by it, which is achieved by shifting the wedge adjustment wedge in a transverse direction.
  • the work roll possibly supported by the back-up roll via the intermediate roll interacts with a further work roll of the roll stand, a roll gap being present between these work rolls.
  • the further work roll and optionally the intermediate roll can also be supported by a further support roll and, together with this, can be displaceably guided on the stand by means of at least one, in particular mechanical or hydraulic, adjusting device for setting the roll gap.
  • the back-up rolls and the work rolls and optionally the intermediate roll are each guided at the end via a bearing unit on the stand.
  • the support roller which can only be adjusted via the wedge adjustment of the roll stand or not adjusted, is supported on the actuator via an end-side bearing unit or both end-side bearing units. If the support roller cannot be adjusted, the actuator is preferably supported directly on the section of the stator. is the support roller can be adjusted exclusively via the wedge adjustment of the roll stand, the actuator is preferably supported indirectly via at least one adjustment wedge of the wedge adjustment on a section of the stand.

  • the piezomechanical actuators are based on piezoceramic transducers, which are integrated directly into the mechanical structure of the vibratory system and directly introduce dynamic forces there.
  • the piezoceramic transducers of a piezo-hydraulic actuator act indirectly on the system via additional hydraulic transducers. In both cases, the required mechanical adjustment amplitude (force / path) is generated via an electrical control of the piezoceramic transducer.
  • Dynamic forces in a frequency range of up to 1 kHz can be introduced via a piezo-mechanical actuator, so that this technology can basically be used for both active damping of 3rd and 5th octave chatter vibrations.
  • the installation location according to the invention between a bearing unit of the support roller and the section of the stator is particularly suitable for the use of piezo actuators because it is highly effective with regard to the active damping of the 3rd octave chatter vibrations in combination with a relatively small actuator volume .
  • the actuator can be arranged between a lower stand cross-head and a bearing unit of the support roller.
  • the actuator is set up to detect rolling forces.
  • an existing load cell can be replaced by the actuator.
  • the usual load cells in the installation area can then be dispensed with, since the actuator takes on the measuring function of a load cell.
  • the measuring principle for the force measurement is either the force measurement via the piezo elements used as an actuator or the force measurement via a separate one force measurement to be integrated into the actuator unit, e.g. B. via strain gauges into consideration.
  • a load cell or load cell is usually located between the adjusting device used to set the pass line, e.g. B. arranged a wedge adjustment and a bearing unit of a support roller.
  • the roll stand comprises at least two corresponding actuators, the bearing units of the support roller each being supported on one actuator and the two actuators each being supported either indirectly via at least one adjusting device for passline adjustment or directly on a section of the stand.
  • two actuators are used per roll stand, one actuator being arranged on a drive-side stand and one actuator on an operator-side stand of the roll stand.

From a control point of view, reducing the vibration amplitude by applying a counter-vibration can also be interpreted as a (controlled) increase in damping, which is why one speaks of "active damping".
  • control electronics are for online monitoring of the vibrations of the roll stand, for online visualization of vibration levels of the vibrations of the roll stand, for automatically starting at least one low-vibration rolling speed and / or for automatically reducing a current rolling speed depending on the currently detected vibrations of the Roll stand set up.
