Definitions

  • the invention relates to a method for the progressive bending of a metal strip, preferably a hot strip, in particular a hot rolled steel strip, in the inlet region of a thornless band reeling device, wherein the metal strip is guided and bent by rotationally driven bending rolls.
  • a bending device for the progressive bending of a metal strip in the inlet region of a thornless band reeling device with a plurality of rotationally driven bending rollers is proposed.
  • hot-rolled, windable metal strip is wound up into a bundle after emerging from a rolling stand or after leaving the last rolling stand of a rolling train in a band reeling device.
  • This winding process can be done either with the involvement of a coiler mandrel or thornless.
  • thornless winding of the metal strip in a Bandcoiler- it is necessary to bend the incoming metal strip in a bending device, so that in the Bandhaspel coupled can form a compact wound coil.
  • the bending device comprises two above a Band carefullyweges arranged driven bending rollers and arranged below the Band properlyweges adjustable and driven bending roller, which is located in the strip running direction of the metal strip at a distance between the two above arranged bending rollers.
  • the adjustable bending roller With the adjustable bending roller the bending radius of the set to be added metal band, with changing tape thicknesses can be considered.
  • the driven upper bending rollers a common drive unit with a transfer case and the lower bending roller associated with a single drive. Since the metal strip has different radii of curvature during its transport through the bending device at the respective contact lines with the bending rollers, local slippage occurs between the bending roller and the metal strip, which leads to surface damage (scoring) on the metal strip.
  • a method according to the preamble of claim 1 is for example from the US-A-2877821 known. Presentation of the invention
  • the object of the present invention is therefore to avoid the disadvantages of the known prior art and to propose a method and a bending device in which slippage between the metal strip and the Anbiegerollen and resulting surface damage to the metal strip are largely avoided.
  • the peripheral speed of all driven bending rollers at the respective contact line with the metal strip surface is set to the surface speed of the metal strip at the contact line.
  • the tape passage path of the metal strip between the bending rollers is determined not only by the position of the bending rollers to each other, but also by feed conditions resulting from the last roll stand or Zu2010rollgang, and by drainage conditions or by repercussions from the Bund Struktur, such as the current Collar diameter, significantly influenced.
  • These complex relationships require an individual control of the driven bending rollers in order to be able to set optimal conditions for the respective operating state. This is ensured by adjusting the peripheral speed of each driven bending roller in the bending device to the surface speed of the metal strip at the respective contact line.
  • the surface velocity of the metal strip at the contact line with the bending roller in dependence on the instantaneous positions of the bending rollers involved in the bending process and state variables of the metal strip determined in a mathematical model and depending on the peripheral speed or set the speed of each driven bending roller.
  • the mathematical model includes a calculation rule for determining the strains and compressions occurring at the contact line of driven bending rolls and metal strip surface and / or the resulting radius of curvature of the metal strip and depending on the calculated values, the peripheral speed or the rotational speed of each driven bending roll is determined set.
  • the metal strip thickness, the metal strip temperature and the quality of the metal strip are incorporated into the mathematical model as default values or as measured values.
  • the inlet and outlet angle of the metal strip in or out of the bending device is of great importance. Especially the outlet angle from the Bending device is significantly influenced by the current collar diameter and changes the tape passage behavior in the bending device.
  • the instantaneous drive torque or a correlating size of one or more driven bending rollers continuously measured and at a drop in the drive torque or falls below a target torque the speed of the rotary drives (drive motors) or the bending rollers or the peripheral speed of the bending rollers in the sense of optimizing the drive torque distribution is changed or regulated.
  • alarm signals can be generated, which allow further manual intervention.
  • each driven bending roller is connected to an independently controllable rotary drive and all rotary actuators a common control device for setting individual peripheral speeds or speeds for each Bending roll assigned.
  • the control device comprises a computing unit with at least one mathematical model for determining the rotational speed or peripheral speed of each driven bending roller with respect to the respective contact line with the metal strip surface, wherein the rotational speed or the circumferential speed in dependence on the instantaneous positions of the bending roll involved in the bending process and of State variables of the metal strip is determined.
  • the mathematical model is based on the principles of strength theory and takes into account the material behavior of the metal strip in the elastic and plastic range.
  • the bending device comprises at least three driven, independently controllable bending rollers.
  • the control of the bending rollers here refers exclusively to the rotary drive of the bending rollers.
  • Each rotary drive a bending roller are associated with measuring devices for detecting the rotational speed of the rotary drive or the bending roller and the drive torque or a correlating size of the rotary drive, and a controller for controlling the speed of the bending roller.
  • the detection of the current drive torque can be done for example by a power consumption measurement with a power consumption meter.
  • At least one of the driven bending rollers is supported in bearing blocks for axially parallel displacement of the bending roller, wherein the bearing blocks are connected to an adjustment and the adjusting device comprises an actuator and a position transmitter and this actuator is operatively connected to the control device.
  • the bearing blocks are assigned guides. These guides can equally be arranged on special guide blocks that do not simultaneously form the bearing blocks.
  • two upper driven bending rollers are supported in bearing blocks for axially parallel displacement of the bending rollers.
  • the two upper bending rollers can be positioned so that the continuous metal strip downstream impose a predetermined curvature becomes.
  • the adjusting blocks associated with the bearing blocks can be controlled independently of one another.
  • the two upper, driven bending rollers are supported and guided in a common support frame.
  • FIG. 1 shows a schematic representation of the basic arrangement of a bending device 1 in the inlet region 2 of a thornless band reeling device 3, which connects to a rolling stand 4 or a last rolling stand 4 of a rolling train.
  • a rollable in the rolling stand 4 wound metal strip 5 is fed via a roller table 6 and arbitrarily configured guide means 7 of the bending device 1 and bent during the passage through the bending device 1 and provided with a curvature, after the entry of the metal strip in the thornless tape coiler 3, the winding the metal band to a compact wound collar 8 allows.
  • the collar 8 is indicated by a dashed line with a small diameter in an intermediate position of the winding process and with dotted line with its maximum diameter.
  • the wound collar is supported during the winding process on two rotatable support rollers 10.
  • the bending device 1 comprises three rotationally driven bending rollers 11, 12, 13, of which two bending rollers are arranged above and one bending roller below a band passageway 14. Thus, a three-point bend of the implemented by passing metal strip.
  • Each bending roller 11, 12, 13 is associated with a rotary drive 15, 16, 17 formed by an electric motor, wherein the rotary drives can be controlled independently of one another as required.
  • the rotary actuators are connected to a control device 18 common to all rotary drives via signal lines for transmitting actual values of the rotary drives to the control device and manipulated variables from the control device to the rotary drives.
  • the bending rollers 11, 12, 13 are rotatably mounted in bearing blocks 19, 20, 21, which in turn are supported in a housing, not shown, of the bending device.
  • At least one, in the illustrated embodiment, two of these bearing blocks 19, 20 are slidably supported on guides 22 for axially parallel displacement of the bending rollers 11, 12 and connected to an adjusting device 23 for implementing changes in position of the bending rollers 11,12.
  • the adjusting devices 23 each comprise an actuator 24 formed by a pressure medium cylinder, to which a position transmitter 25 is assigned. From the position sensor, the respective actual position of the bending roller can be transmitted to the control device 18 and manipulated variables are applied to the actuator 24. With the controlled positioning of the bending rollers 11, 12 relative to the further bending roller 13, the curvature of the metal strip can be specified at the output from the bending device as a function of various influencing variables.
  • the invention is in no way limited to the positioning of the upper bending rollers 11, 12 relative to the further bending roller 13.
  • the adjustment of the bending rollers relative to one another can take place more or less equally by the displacement of one or more bending rolls forming the bending device.
  • the employment can hereby with different structural solutions, for example linear, as in FIG. 1 represented, or with a lever or a lever system.
  • FIG. 2 illustrates the strip pass of the progressively curved metal strip through the bending device along the tape passage 14.

  • a largely slip-free transmission of a drive torque from the driven bending roller on the metal strip is only possible if the surface speed of the metal strip at the contact line of the bending roller with the metal strip surface of the peripheral speed of the bending roller or taking into account the roller diameter of the rotational speed n 11 , n 12 , n 13 the driven bending roller corresponds.
  • all bending rollers of the bending device are driven rollers. It is well within the scope of the invention, if one or more of the bending rollers form only with the metal belt follower rollers, however, make a contribution to the bending of the metal strip.

  • inlet and outlet conditions can be defined and taken into account, for example, resulting from the tape length in the inlet side belt run or by transport-related forces or occur on the outlet side by the continuously increasing collar diameter.
  • the rotary actuators are assigned an anti-slip regulation.
  • the rotational speeds of the individual bending rollers or the rotary drives and the current consumption values of the rotary actuators are continuously detected and fed to regulators for speed control.

Sudden changes in the current consumption of individual bending rollers are a criterion for the occurrence of slip and trigger the regulation. This can be done for example by voltage correction signals.
