Definitions

  • JP-A 2004268084 It is known to regulate the strip thickness at the exit of a tandem rolling mill by avoiding strong strip tension changes between the individual rolling stands.
  • the roller circumferential speed of the roll stand N upstream of the roll stand N-1 is adjusted by means of a coefficient. The coefficient is determined based on the deviation between the target value of the strip thickness and the tape exit thickness estimated by the mass flow law.
  • the present invention further relates to a computer program comprising machine code which is directly executable by a control device of a multi-stand rolling mill and whose execution by the control means causes the control means to control the cold rolling mill according to such a control method. Furthermore, the present invention relates to a data carrier with a stored on the disk such a computer program.
  • a device for strip thickness control in single-stand cold rolling mills wherein the device comprises a reel for the incoming in the rolling stand of the cold rolling mill strip part and a reel for the expiring from the rolling mill strip part. It is provided a device for controlling the speed of the uncoiler in the sense that the speed of the incoming band part is controlled in relation to the speed of the expiring band part according to the desired stitch reduction.
  • the corresponding mass flow principle is realized by these measures and the application of this principle for the regulation of multistage cold strip mills is basically known.
  • the strip thicknesses and the strip tensions are usually set according to the mass flow control concept, preferably in the extended variant, in which a belt-feed device arranged on the inlet side is considered to be the zero-stage rolling stand.
  • the desired belt thicknesses are quasi-automatically set.
  • the overfeed of the actual speeds of the cold strip in the individual sections relative to the roller speeds is an uncertainty factor.
  • the increasingly high demands on the dimensional stability of the rolled products therefore require new methods in order to be able to eliminate these uncertainties in the overfeed.
  • the object of the present invention is to provide possibilities by means of which the outgoing actual thicknesses of at least one of the rolling stands can be set correctly.
  • the possibility should in this case be combined with a correct setting of the inlet-side mass flow.
  • the computer program is designed such that it causes these measures.
  • the disk has a corresponding computer program.
  • the cold rolling mill according to the invention has such a control device, so that the control device in operation operates the cold rolling mill according to such a control method.
  • the mass flow controller also receives the basic output signal.
  • the zeroth forward regulator emits its output signal when the zeroth forward regulator is switched on. This latter measure results in a smoother, more stable connection of the zeroth forward controller.
  • control device has a first forward regulator, which receives the first actual thickness from the first thickness detection device.
  • first feedforward controller simulates the first setpoint speed and the zero setpoint speed.
  • the first forward regulator emits its output signal when the first forward regulator is switched on. This latter measure results in a smoother, more stable connection of the first forward regulator.
  • control method can also be implemented in the computer program and the control device.
  • control device can be implemented by circuitry. In general, however, the control device is designed as a programmable control device, which executes a computer program of the type described above during operation.
  • the tape feeding device may be formed as needed.
  • it can be designed as an S-roll set or as a uncoiler.
  • 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 cold rolling mill furthermore has a strip feeding device 3.
  • the strip feeding device 3 is arranged upstream of the rolling stand 2-1 which has passed through first.
  • the tape feeder 3 is according to FIG. 1 designed as an S-roll set.
  • the tape feeder 3 will be hereinafter referred to as "zeroth mill stand”. Corresponding elements and sizes that relate to the tape feeder 3, if necessary, provided with the suffix "-0".
  • the cold rolling mill further comprises a first thickness detecting device 4-1.
  • the first thickness detection device 4-1 is arranged downstream of the first continuous rolling mill 2-1, that is to say between the first pass through the rolling stand 2-1 and the next rolling mill 2-2.
  • a first actual thickness d-1 of the cold strip 1 is detected, that is to say the actual thickness d-1, with which the cold strip 1 runs out of the rolling mill 2-1 first passed through.
  • the control device 5 carries out a control method, which will be explained in detail below. Due to the operation of the control device 5, the cold rolling mill is thus operated according to such a control method.
  • the control device 5 of the strip feeding device 3 supplies a zeroth setpoint speed v-0 *.
  • the tape feeder 3 receives the zeroth set speed v-0 * and adjusts itself so that it feeds the cold strip 1 to the first passed through stand 2-1 with a zeroth actual speed v-0.
  • the zeroth actual speed v-0 corresponds in this case to the zeroth setpoint speed v-0 *.
  • the band feeding device 3 may have, for example, a zeroth speed controller 6-0 which correspondingly controls the zeroth actual speed v-0 of the band feed device 3.
  • the tape feeder 3 is, as already mentioned, logically considered zeroth mill stand. However, it does not roll the cold strip 1. An overfeed or the like therefore does not occur with respect to the tape feeder 3.
  • the peripheral speed of the tape feeder 3 therefore corresponds directly to the zeroth actual speed v-0. It only needs to be noted that the cold strip 1 does not slip.
  • control device 5 supplies the first rolling mill 2-1, which has passed through, to a first setpoint speed v-1 *.
  • the first run through stand 2-1 receives the first target speed v-1 * and turns this way in that rollers 7-1 of the first-pass rolling mill 2-1 rotate at a first actual speed v-1 corresponding to the first target speed v-1 *.
  • the first rolled mill 2-1 rolls the cold strip 1.
  • the cold strip 1 therefore exits from the first pass through stand 2-1 with an overfeed.
  • An actual speed v'-1 of the cold strip 1 behind the first passed through stand 2-1 is therefore greater than the first actual speed v-1. This will be discussed later in more detail.
  • the first actual thickness d-1 is detected.
  • the first thickness detection device 4-1 supplies the first actual thickness d-1 of the control device 5 detected by it.
  • the control device 5 receives the first actual thickness d-1.
  • the control device 5 has a thickness regulator 8 internally.
  • the thickness controller 8 may be designed, for example, as a P, PI, PID, or other controller.
  • the thickness regulator 8 is supplied with the first actual thickness d-1 and a first desired thickness d-1 *.
  • the thickness controller 8 determines a basic output signal ⁇ .
  • the control device 5 performs the first setpoint speed v-1 *, so that the first actual thickness d-1 of the cold strip 1 is adjusted to the first setpoint thickness d-1 * of the cold strip 1.
  • the basic output signal ⁇ serves only for tracking the first setpoint speed v-1 *.
  • the zeroth setpoint speed v-0 * is not tracked, at least not based on the basic output signal ⁇ .
  • the cold rolling mill further has a zeroth thickness detecting device 4-0.
  • the zeroth thickness detecting device 4-0 is disposed between the tape feeder 3 and the first passed through stand 2-1. It detects a zeroth actual thickness d-0 of the cold strip 1, that is to say the actual thickness d-0, with which the cold strip 1 enters the first rolling stand 2-1.
  • the zeroth thickness detector 4-0 supplies the zeroth actual thickness d-0 to a zeroth forward controller 9-0.
  • the zeroth forward regulator 9-0 is in this case part of the control device 5.
  • the zeroed forward regulator 9-0 accepts the zeroth actual thickness d-0. It performs the zero setpoint speed v-0 * in such a way that the product of zero setpoint speed v-0 * and zero actual thickness d-0 is set to a desired mass flow.
  • the zeroed forward regulator 9-0 preferably takes into account a distance that the zeroth thickness detection device 4-0 has from the rolling stand 2 - 1 passed through first, a dynamics of the belt feed device 3 and the time course of the zeroed actual speed v - 0. By these measures can - according to a tracking - be achieved that the tape feeder 3 time correct (namely, when the respective corresponding point of the cold strip 1, the first traversed mill stand reached 2-1) with the corresponding zero set speed v-0 * is applied.
  • control device 5 can also have a first forward regulator 9-1.
  • the first forward regulator 9-1 receives the first actual thickness d-1 from the first thickness detection device 4-1.
  • the first forward regulator 9-1 performs the first target speed v-1 * and the zero target speed v-0 * in a similar manner.
  • This embodiment does not contradict the regulation by the thickness controller 8, because the regulation by the first forward regulator 9-1 has a different (greater) dynamic than the regulation by the thickness regulator 8.
  • the mass flow controller 10 may optionally accept the basic output signal ⁇ from the thickness controller 8.
  • the zeroth actual thickness d-0 is supplied to the mass flow controller 10 from the zeroth thickness detector 4-0.
  • the zeroth actual speed v-0 can be detected relatively easily, since the band feed device 3 does not reshape the cold strip 1. It only has to be ensured that the cold strip 1 has no slippage with respect to the strip feed device 3.
  • the speed v'-1 of the cold rolled strip 1 between the first passed rolling stand 2-1 and the next passed rolling stand 2-2 can be determined by modeling the behavior of the cold strip 1 in the first passed through stand 2-1 in conjunction with the first actual speed v 1 of the rolls 7-1 are determined.
  • other approaches are possible.
  • the mass flow controller 10 determines an additional output signal ⁇ on the basis of the quantities supplied to it (ie the two speeds v-0 and v'-1, the zeroth actual thickness d-0 and optionally the basic output signal ⁇ ). Based on the additional output signal ⁇ - analogous to the basic output ⁇ - the first target speed v-1 * tracked, so that the first actual thickness d-1 of the cold strip 1 is equalized to the first target thickness d-1 * of the cold strip 1. On the other hand, analogous to the basic output signal A, the zeroed setpoint speed v-0 * is not tracked on the basis of the additional output signal 8.
  • the embodiment according to FIG. 2 makes sense, since the correction by the additional output signal 8 - in contrast to the correction by the basic output signal A - is relatively inaccurate, but with much greater dynamics is possible.
  • FIG. 3 essentially shows a similar embodiment as FIG. 1 ,
  • the difference to the design of FIG. 1 is that in addition ramp generator 11 and multiplier 12 are present.
  • the ramp generators 11 gradually increase their output signals from zero to one.
  • the multipliers 12 receive the output of their respective ramp generator 11 and the output of the zeroth and the first forward regulator 9-0, 9-1, respectively, and output as their output the product of their two input signals.
  • the multipliers 12 in conjunction with the ramp generators 11 have the effect of outputting the output of the zeroth and first feedforward controllers 9-0, 9-1, respectively.
  • the feeding of the respective start signal S to the ramp generators 11 takes place at a suitable time.
  • the time is chosen such that it falls within a time range at which a tape head of the cold strip 1 has not yet run into the first rolled stand 2-1 or indeed has already leaked out of the first passed rolling mill 2-1, but still was not entered in the next run through rolling mill 2-2.
  • the ramping therefore takes place during rolling of the cold strip 1.
  • the control device 5 of 1 to 3 can be realized in terms of circuitry. In many cases, however, the control device 5 will be correspondingly FIG. 4 be designed as (software) programmable control device which executes a computer program 13 during operation. Regardless of whether the control device 5 is realized in terms of circuitry or is (software-) programmable, the control device 5 may alternatively be a control method according to the above-explained basic principle of the present invention or a control method according to one of the above-explained preferred embodiments of the control method according to the invention realize.
  • control device 5 is software-programmable
  • the corresponding computer program 13 has machine code 14.
  • the machine code 14 can be executed directly by the control device 5.
  • the execution of the machine code 14 by the controller 5 causes the controller 5 to control the cold rolling line according to one of the above-explained control methods.
  • the computer program 13 can already be deposited in the control device 5 during the production of the control device 5. Alternatively, it is possible to supply the computer program 13 to the control device 5 via a computer-computer connection (for example a LAN or the Internet). Again alternatively, it is possible to store the computer program 13 on a data carrier 15 and the computer program 13 to supply the control device 5 via the data carrier 15. Purely by way of example is in FIG. 4 the disk 15 shown as a CD-ROM. However, it could alternatively be designed differently, for example as a USB memory stick or as a memory card.
  • FIG. 4 shows two alternative embodiments of the tape feeding device 3, namely on the one hand as an S-roll set (as in the 1 to 3 ) and on the other hand as uncoiler (only in FIG. 4 ).
  • the latter embodiment of the band feeding device 3 is of course also in the Kaltwalzstra ⁇ en according to the 1 to 3 realizable.
  • the present invention has many advantages. In particular, it is achieved that the first actual thickness d-1 of the cold strip 1 is set correctly. In connection with the zeroth forward regulator 9-0, it is also achieved that the mass flow through the cold rolling mill is also set correctly. Nevertheless, the control engineering structure of the control device 5 on a captivating simplicity. In particular, only a few interlinked regulations are required. Furthermore, during operation of the cold rolling train according to the invention, a significantly improved dimensional accuracy of the actual thickness d-n behind last passed rolling mill 2-n of the cold rolling mill, both under static operating conditions and under dynamic operating conditions (for example, accelerating or decelerating the cold strip 1 or weld pass). Furthermore, the additional output signal 8 of the mass flow controller 10 is a direct indication of the modeling quality of the overfeed and can thus be used in an outstanding manner for a possible adaptation of a process model 16.
