  • control method according to the invention can in principle be used in any of the rolling stands of the cold rolling mill. It is also possible to use the control method according to the invention simultaneously in several rolling stands of the cold rolling mill. It is preferred that at least the rolling mill of the cold rolling train, which is first passed through by the cold strip, is regulated in accordance with the invention.

  • the computer program can be stored on a data carrier in machine-readable form.
  • the object is achieved by a cold rolling train, in which - in addition to the features mentioned above - the control device is designed in accordance with the invention, so that the cold rolling train is operated according to a control method according to the invention.
  • a cold rolling mill for rolling a cold strip 1 has a plurality of rolling stands 2.
  • the rolling stands 2 are passed through by the cold strip 1 in succession.
  • the reference numeral 2 As far as below generally speaking only of the rolling stands 2 of the cold rolling mill, only the reference numeral 2 itself is used for the rolling stands 2. Partially, however, the reference numeral 2 - separated by a hyphen - a digit or letter n readjusted.
  • "2-1" denotes the rolling mill 1 first passed through by the cold-rolled strip 1
  • "2-2" the rolling mill etc. next passed by the cold-rolled strip 1
  • “2-n” denotes the rolling stand of the cold rolling line last passed by the cold strip 1.
  • the shorter notation will be referred to briefly as the first rolling stand, the second rolling stand, etc. up to and including the last rolling stand, because of the respective rolling stands 2-1, 2-2, etc.
  • the cold rolling mill is preceded by a strip feeding device 3, via which the cold strip 1 is fed to the first rolling stand 2-1.
  • the tape feeder 3 is according to FIG. 1 designed as a rewinder.
  • the speed detection device 4 an actual speed v is detected by measurement, with which the cold strip 1 from the speed detection device 4 upstream rolling stand 2 (here: the first rolling stand 2-1) expires.
  • the detected actual speed v is - with the exception of unavoidable measuring errors - directly with the actual speed the cold strip 1 identical.
  • the actual speed v is, in particular, not a roller peripheral speed vU of the upstream rolling stand 2, that is to say a size that is linked to the actual speed of the cold strip 1 only via an overfeed. Also, it is not a roller peripheral speed vU 'of a downstream roll stand 2, according to FIG. 1 Rolling mill 2-2.
  • the design of the speed detection device 4 can be made as needed.
  • a role are employed on the cold strip 1, which runs along with the cold strip 1 and whose speed is detected, for example by means of a pulser.
  • Optical measuring methods in particular laser measuring methods, are also known.
  • the same rolling mill 2-1 is further downstream of a thickness detection device 5.
  • a strip thickness d is measured, with which the cold strip 1 from the thickness detection device 5 upstream rolling stand 2 (here: the first rolling stand 2-1) expires.
  • the detection of the actual speed v is possible virtually without delay.
  • the exact arrangement of the speed detection device 4 is therefore of secondary importance.
  • the detection of the strip thickness d can only be delayed, since the strip thickness d can only be detected locally at the location of the thickness detection device 5 and from the expiry of the cold strip 1 from the upstream rolling stand 2-1 passes until reaching the thickness detection device 5, a transport time.
  • the thickness detection device 5 is arranged as close as possible to the upstream rolling stand 2-1 in order to keep the transport time as low as possible and therefore to achieve the highest possible dynamics.
  • the detected actual speed v and the detected strip thickness d are fed to a control device 6 of the cold rolling train.
  • the control device 6 evaluates the actual speed v supplied to it and the strip thickness d fed to it and controls the respective rolling stand 2 - according to the embodiment of FIG. 1 the first rolling stand 2-1 - accordingly. This is done as follows:
  • the control device 6 compares the detected actual speed v of the cold strip 1 with a corresponding desired speed v *, that is, with the speed at which the cold strip 1 is to run out of the upstream rolling stand 2-1. Based on the comparison, the control device 6 performs a desired value vU * for the circumferential roll speed vU of the respective rolling stand 2-1, so that the actual speed v of the cold strip 1 is adjusted to the desired speed v *. Corresponding to the tracked nominal value vU * for the roller circumferential speed vU, the control device 6 controls the relevant rolling stand 2-1.
  • the control device 6 can correspond to FIG. 1 implement an underlying controller structure in the simplest case: an external setpoint-actual controller determines the setpoint vU * for the roller peripheral speed vU based on the difference between the actual speed v of the cold strip 1 and the corresponding setpoint speed v *, an internal controller regulates the difference of the setpoint vU * for the roller peripheral speed vU and the roller peripheral speed vU itself, the roller circumferential speed vU.
  • the procedure is different. The preferred procedure is described below in connection with FIG. 2 explained in more detail.
  • the reciprocal of the overfeed a is fed to a multiplier 8, which determines the corresponding desired value vU * for the circumferential roll speed vU on the basis of the setpoint speed v * of the cold strip 1.
  • FIG. 2 is determined on the basis of the comparison of target speed v * and actual speed v of the cold strip 1 - in particular on the basis of the difference - a correction factor k, based on which the roll gap model 7 is adapted. Due to the adaptation of the roll gap model 7, the overfeed a determined by the roll gap model 7 changes (inter alia). The tracking of the target value vU * for the circumferential roll speed vU is performed according to FIG. 2 Thus realized indirectly, namely the fact that the roll gap model 7 on the basis of the comparison of the actual speed v of the cold strip 1 with the target speed v * is adapted.
  • the control device 6 can be implemented in individual cases circuit technology. In general, the control device 6, however, according to the illustration of FIG. 1 designed as a software programmable controller 6. This is in FIG. 1 indicated by the letters " ⁇ P" (for microprocessor). In this case, the control device 6 executes a computer program 10 with which the control device 6 is programmed.
  • the computer program 10 has according to FIG. 1 Machine code 11, which is directly executable by the control device 6.
  • executing the machine code 11 by the controller 6 causes the controller 6 to control the cold rolling line according to the above-explained control method.
  • the computer program 10 can be supplied to the control device 6 in any manner.
  • a supply via a computer-computer connection is possible.
  • suitable computer-computer connections are a local area network (LAN) and the World Wide Web.
  • LAN local area network
  • LAN local area network
  • a data carrier 12 on which the computer program 10 is stored in machine-readable form.
  • suitable data carriers 12 are a CD-ROM, a USB memory stick or an SD memory card.
  • the data carrier 12 is designed as a USB memory stick.
  • the present invention has many advantages.
  • a defined mass flow and at the same time a correct strip thickness can be achieved in a simple manner. Therefore, it is only necessary for the roll stands 2, which are arranged downstream of the roll stand 2-1 regulated according to the invention, to correctly set the roll peripheral speed vU 'of the respective roll stand 2.
  • This can alternatively take place in that behind the respective rolling stand 2 (for example, the second rolling stand 2-2) by means of a corresponding speed detection device 13, the actual Actual speed is detected and controlled behind this rolling stand 2 or that over a corresponding roll gap model, the respective overfeed is modeled and in this rolling stand 2-2 outlet side desired belt speed is converted into the corresponding circumferential roll speed vU '.
  • a conventional monitor control for the last fine correction of the final strip thickness that is, for the strip thickness of the cold strip 1 behind the last rolling stand 2-n
  • the regulation of the mass flow according to the invention shows its advantages not only under static operating conditions, but above all under dynamically changing operating conditions such as, for example, the threading operation, the passage of a weld seam or the changing of the setpoint speed v *. It also results in these operating conditions improved dimensional accuracy of the final strip thickness. Furthermore, the extent of the required adaptation of the roll gap model 7 is a direct indication of the quality of the roll gap model 7. This indicator can also be used generally for optimizing process models for the cold rolling mill. The dynamic of the control is limited - even in dynamic operating conditions - only by the speed of the cruise control. Furthermore, a continuation of the operation of the cold rolling mill is possible even in case of failure of the speed detection.
