Definitions

  • the input thickness is measured by means of a front thickness gauge upstream of the considered roll stand.
  • a front thickness gauge is used arranged between the first and the second roll stand of the rolling train.
  • This embodiment can also be maintained within the scope of the present invention.
  • the arrangement of the front thickness measuring device - if required - freely selectable. It could, for example, also be arranged in front of the first roll stand of the rolling train.
  • FIG. 1 has a multi-stand rolling mill several rolling stands 1 to 5.
  • the rolling stands 1 to 5 are run through by a band 6 in succession. Shown here are in FIG. 1 five rolling mills 1 to 5.
  • the rolling mill could alternatively more or less rolling mills 1 to 5, for example 3, 4, 6, 7, ... rolling mills.
  • the rolling mill of FIG. 1 designed as a cold rolling mill (tandem mill). This embodiment is the standard case. Exceptionally, however, the present invention could also be applied to a hot strip mill.
  • FIG. 1 In front of the first rolling stand 1, a uncoiler 7 and a front S-roller set 8 are arranged. Behind the last rolling stand 5, a rear S-roller set 9 and a reel 10 are arranged. The presence of the reel 7, 10 and the S-roller sets 8, 9 is common, but not mandatory.
  • the rolling stands 1 to 5, the reel 7, 10, the S-roller sets 8, 9 and the thickness measuring devices 11, 12 are connected to a control device 13 for the multi-stand rolling train data technology.
  • the control device 13 is configured to operate the rolling mill in accordance with an operating method which will be described below in connection with FIGS FIGS. 2 to 7 will be explained in detail.
  • the computer program 14 may have already been deposited in the control device 13 during the production of the control device 13. Alternatively, it is possible to supply the computer program 14 to the control device 13 via a computer-computer connection.
  • the calculator-computer connection is in FIG. 1 not shown here. It can be designed, for example, as a connection to a LAN or to the Internet. Again alternatively, it is possible to store the computer program 14 on a data carrier 16 in machine-readable form and to feed the computer program 14 to the control device 13 via the data carrier 16.
  • the design of the data carrier 16 is arbitrary nature. For example, it is possible that the data carrier 16 is designed as a USB memory stick or as a memory card. Is shown in FIG. 1 an embodiment of the data carrier 16 as a CD-ROM.
  • step S6 the control device 13 determines a setting command for the second rolling stand 2 (or one of the following rolling stands 3 to 5), also taking into account the strip thickness d1 detected on the outlet side of the first rolling stand 1.
  • the outputting of the control command to the second rolling stand 2 (or the corresponding downstream rolling stand 3 to 5) is preferably not immediately after the determination of the control command, but only when the corresponding section 17 of the belt 6 in the second rolling stand 2 (or the corresponding subsequent roll stand 3 to 5) is rolled.
  • the corresponding time can be determined on the basis of the tracking of the sections 17 without further ado.
  • the further measures include at least one of the steps S16, S17 and S18. Since each one (but not all of them) of steps S16, S17 and S18 is optional, steps S16, S17 and S18 in FIG FIG. 3 dashed lines.
  • step S17 the control device 3 determines a setting command for the third rolling mill 3 (or a subsequent roll stand 4, 5).
  • the determination of the control command for the third roll stand 3 (or the corresponding following roll stand 4, 5) takes place here also taking into account the strip thickness d2, with which the belt 6 expires from the second roll stand 2.
  • the control command for the third rolling stand 3 (or the corresponding downstream rolling stand 4, 5) is preferably not immediately output to the third rolling stand 3 (or the corresponding downstream rolling stand 4, 5), but only when the corresponding section 17 in the third rolling stand 3 (or the corresponding nearby rolling stand 4, 5) enters.
  • the last roll stand 5 of the rolling mill whose input thickness is d4 according to the above in connection with FIG. 3 determined method determined. Furthermore, the last rolling stand 5 is operated in a manner according to the invention. However, it differs from the above in connection with FIG. 3 explained procedure. The procedure for the last roll stand 5 will be described below in connection with FIG. 4 explained in more detail. Since the procedure of FIG. 4 however, over long distances with the practices of FIG. 2 and 3 If possible, reference is made to the explanations given there.
  • Step S32 to S34 be present.
  • the controller 13 determines the value of a logical variable OK.
  • the logical variable OK assumes the value TRUE then and only if the determined strip thickness d5 does not deviate too much from the measured outlet thickness d5 '. Otherwise, the logical variable OK assumes the value FALSE.
  • the measuring device based on the location for which the respective speed v1 to v5 apply, are formed as rollers 21 of the upstream rolling stand 3 and that the measured variable with the peripheral speed vW of the respective rollers 21 corresponds.
  • the peripheral speed vW of the rollers 21 is fed to a model 22 in which the lead of the belt 6 in the respective rolling stand 3 is modeled.
  • the model 22 is usually implemented within the control device 13 here.
  • the model 22 determines in this case the respective speed v0 to v5 of the belt 6 on the basis of the respective roller peripheral speed vW and the lead of the belt 6 in the respective rolling stand 1 to 5.
