By means of the wear model, the expected current wear of the respective roller is determined as a function of the rolled section of the rolling stock, the course of the rolling force over this route, etc. The wear model makes the determined expected present wear and tear available to other control systems, for example for the corresponding correction of the employment.

  • roll travel is familiar to any person skilled in the art. These are the individual lengths of the various flat rolled goods 1, which have already been rolled by means of the considered roll 3 and - in the future roll travel - are still rolled. The roll travel can be visualized as if the flat rolled stock 1 were to stand still in the nip of the rolling stand 2 in which the considered roll 3 was installed, and the corresponding rolling stand 2 would move along the flat rolled stock 1 during the rolling.

Also, the control computer 4, for example, a maximum allowable width for future to be rolled flat rolling 1 determine and spend.
  • Step S4 the control computer 4 checks whether - with respect to the roller 3 considered - a roll change is performed. If this is the case, the roll change is performed in a step S5.
  • Step S5 is in FIG. 2 only dashed lines, because the roll change itself - ie the removal of the previously used roller 3 and the incorporation of another roller 3 - although in the course of FIG. 2 must be taken into account, but as such is not performed by the control computer 4.

  • the control computer 4 determines in step S10 the new expected present actual wear V of the roller 3 under consideration.
  • the control computer 4 starts from the already given actual wear V of the considered roller 3, determined by means of the wear model 8 an incremental wear increase ⁇ V for the respective execution of step S7 and adds the incremental wear increase ⁇ V to the already existing actual wear V.
  • the result corresponds to the new expected actual wear V.
  • the expected current actual wear V starting from the initial state of the considered roll 3, is determined step by step by adding up the respective incremental wear increases ⁇ V.
  • the control computer 4 therefore determines the expected present actual wear V from the initial state of the roller 3 under consideration.

As a result, the control computer 4 thus determines the expected present actual wear V on the basis of the actual variables I detected during the previous roller travel of the roller 3 considered.

  • the respective wear model 8 (or the corresponding parameters) follow, so to speak, the respective roller 3 on its way from the rolling mill in the grinding shop 11, from there to warehouse 10 and from there back to the rolling mill.
  • the wear model 8 is initialized in a roll change (see the step S6 in FIG. 2 ).
  • the initialization may, for example, be designed as described below in connection with FIG. 10 is explained in more detail.
  • the roller 3 to be installed does not always have to be installed in the same rolling stand 2.

As a rule, the same type of roller 3 is always installed in a specific one of the rolling stands 2. In some cases, however, the type can vary. For example, in the second rolling mill 2 of FIG. 1 Alternatively, a roller of the surface material "high speed steel” (HSS) or from the surface material “high chrome cast iron” (HC, high chrome) or from the surface material "shell casting” (IC, English indefinite chill) are installed , In practice, it has been found that the wear of a roll 3 may also depend on which type of roll 3 in the immediately upstream roll stand 2 is installed.

The value of the logical variable OK is retrieved in a step S66. Depending on the value of the logical variable OK, steps S63 and S64 are executed or skipped. As an alternative to skipping steps S63 and S64, it is further possible for the control computer 4 to issue a corresponding warning to the operator 9 of the rolling mill or to another person. In this case, the steps S63 and S64 are executed only if the control computer 4 is externally specified by a human an explicit corresponding statement.

Alternatively, it is according to FIG. 13 possible that the control computer 4 additionally takes into account at least one actual actual wear VE and the corresponding expected present actual wear V at at least one point of the considered roller 3, which lies outside the middle of the considered roller 3.
