Definitions

  • the invention relates to a rolling mill and to a method for flexible cold or warm disposable or reversing rolling of metal strip, in particular of steel, with variable strip thickness, with a roll stand having a set of rolls and a Anstellsystem for adjusting the roll gap, one of the rolling mill upstream Uncoiler and a rolling mill downstream reel for the rolled strip, which are equipped with a variable speed drive.
  • the EP 1 121 990 A2 describes a rolling mill for flexible rolling of strip material with a periodically varying strip thickness. Between the uncoiler and the roll stand and the hanger and the roll stand a Ausretesry disrupt dancer roll is arranged, around which the strip material is looped around. The position of the dancer roller to the horizontal belt plane is force-controlled to compensate for a changing material flow or a changing belt speed due to a changing material jam at the roll nip input and a changing material lead at the nip exit with an adjustment of the roll gap and set a constant strip tension.
  • the position changes of the dancer rollers due to the balance problems between the tape take-off from the uncoiler and the tape feeder in the nip and / or between the tape exit from the nip and the winding of the tape on the reel are continuously determined and in signals for speed control of the uncoiler and the coiler implemented.
  • the periodicity of the strip thickness change is determined, and a disturbance variable is applied to compensate for the acceleration forces acting on the dancer rollers.
  • a rolling mill for flexible rolling of metal strips in which the strip tensioning on the metal strip is regulated by means of a strip tension compensation device.
  • the tape tension compensation device is formed by a deflection roller which is displaceable or pivotable for changing the distance between the tape reels and the nip. By adjusting the deflection roller, the strip running geometry is adapted to the strip length located in each case between the reel and the rolling stand and thus the desired strip tension is maintained.
  • an S-roll unit is used as a tape storage, which is equipped for Bandzugregelung with a pivoting pulley with a hydraulic linear actuator, wherein at least one of the two pulleys is rotationally driven in order to optimally influence the tensile structure in the band.
  • the invention has for its object to develop a rolling mill and a method for flexible rolling of metal strip, compared to the rolling mills and rolling processes of the prior art for flexible rolling of strip material higher rolling speeds, taking into account the physical boundary conditions such as tape storage length, inertias of the actuators and band tension error due to deviation from the ideal acceleration characteristic, in particular in the reversal points of the band acceleration when the band thickness profile changes, and by avoiding abruptly opposite mass accelerations of the tape storage devices.
  • Figure 1 shows the schematic structure of a four-high mill for flexible cold-disposable rolling of metal strip with variable strip thickness.
  • the rolling mill comprises a roll stand 1, in which two work rolls 2, 3 and two support rolls 4, 5 and a setting system for adjusting the roll gap 6 are installed, a roll stand 1 upstream reel 7 and a roll stand downstream reel 8 for the rolled strip.
  • the host computer for the regulation of Banddickenprofils the strip thickness course additionally passes as a function of time to a Material Wegdiktor that generates a pilot-controlled torque application for the speed control of uncoiler and reel, taking into account the material backlog at the tape inlet side and the material advance on the strip outlet side of the rolling stand and in knowledge of the drive-specific torque control times.
  • This torque precontrol can be positive or negative depending on the thickness transition thick-thin or thin-thick and of the rolling direction.
  • the entire rolling process is carried out with a length segment and / or time segment control.
  • the rolling mill shown in Figure 2 is equipped with a arranged between the pay-off reel 7 and the roll stand 1 tape storage 10 and another between the roll stand 1 and the reel 8 arranged strip accumulator 11.
  • the band memories 10, 11 are used to compensate for remaining residual errors in the mass flow of the rolled strip due to the limited drive dynamics of the reel drives in the area of the reversal points of the belt acceleration with a change in the strip thickness profile.
  • the tape storage 10, 11 are each formed as an S-pair of rollers 12 having an upper and a lower guide roller 13, 14, an eccentric mounting of the axes of rotation 15, 16 of the upper and lower guide rollers 13, 14 in bearing units 17, 18 and a variable Adjustment of the mutual position of the axes of rotation 15, 16 of the two guide rollers 15, 16 by a rotational adjustment of one or both axes of rotation 15, 16 about the bearing units 17, 18 by means of a rotary drive for setting different loop lengths of in a loop 19 around the two guide rollers 13, 14th rolled strip 9 guided by the S-roller pair 12.
  • the different loop lengths are used in conjunction with the eccentric adjustment Fast tape storage used to catch remaining deviations from the target acceleration.
  • the eccentric adjustment has the advantage over the known tape stores that the adjustment can be made comparatively quickly, since no large masses with corresponding inertia have to be accelerated over a large distance.
  • the eccentric adjustment of the axes of rotation of the pulleys of the S-roller pair can be carried out both pilot-controlled by the Material Wegdiktor as well as regulated by the measured strip tension.
  • the rolling process can also be extended by returning process measured values, such as, for example, strip tension and / or eccentric adjustment force, as opposed to the calculated determination of state variables.
  • the angle of rotation of the eccentric adjustment of the axis of rotation 15 of at least one deflection roller 13 of the S-roller pair 12 is determined from the Exzenterausgangsgna and as a function of the belt speed error from the acceleration deviation.
  • the angular velocity of the eccentric adjustment of the axis of rotation 15 of at least one deflection roller 13 of the S-roller pair 12 is determined from the Exzenterausgangsgna and as a function of the belt speed error from the acceleration deviation.
  • the angle of rotation and the angular speed of the eccentric adjustment of the axis of rotation 15 of at least one deflection roller 13 of the S-roller pair 12 can be determined from the eccentric output position and depending on the belt speed error from the acceleration deviation.
  • the dead centers of the eccentric adjustment of the rotational axis 15 of at least one deflection roller 13 of the S-roller pair 12 are arranged approximately on the bisector of the wrap angle of the guide roller or the guide rollers.
  • At least one deflection roller 13 of the S-roller pair 12 is equipped with a brake drive.
  • the S-roller section can be equipped with drives for train construction and train dismantling.
  • the S-roller pairs 12 are arranged below the belt running plane 20-20 and the eccentric bearing units 17, 18 of the upper and lower deflection rollers 13, 14 of the S-roller pairs 12 are located in a vertical plane 21-21.
  • the rotation axes 15, 16 of the guide rollers 13, 14 of the two S-roller pairs 12 are rotated about the vertical plane 21-21 of the eccentric bearing units 17, 18 of the guide rollers in a maximum distance from each other.
