Abstract

A method and a system for configuring a strand guiding system (8, 8a, 8b) of a continuous casting machine (2) and such a strand guiding system (8, 8a, 8b). A strand guiding segment (10g-r) guides a metal strand in the strand guiding system (8, 8a, 8b). The strand guiding system (8, 8a, 8b) has a plurality of strand guiding segments (10g-r) and respective control units (22g-r), wherein each control unit (22g-r) identifies its strand guiding segment (10g-r), and each control unit (22g-r) automatically depends on the strand guiding segments (10g-r) identified by the control unit (22g-r). The strand guiding system (8, 8a, 8b) and the strand guiding segment (10g-r) are prepared for the performance of the method herein disclosed.

First claim

The invention claimed is:

1. A method for configuring a strand guiding system of a continuous casting machine, wherein the strand guiding system has a plurality of strand guiding segments and a plurality of control units, and respectively one control unit is assigned to each strand guiding segment, the method comprising:
causing each control unit to identify the respective strand guiding segment assigned thereto by using a segment-specific item of information, which is software and/or hardware coded; and
configuring each control unit substantially automatically in dependence on the strand guiding segment identified by it, by at least one of setting operating parameters and by selection of a computer-readable program code,
wherein the control units are at least one of logically and physically separate, and at least some of the control units that are substantially the same are assigned to strand guiding segments of differing structural types.

2. The method as claimed in claim 1 , wherein the software coding comprises a data item, the method further comprising storing the data item in a storage unit of the strand guiding segment.

3. The method as claimed in claim 1 , wherein the hardware coding comprises a strand segment-specific plug connection of the strand guiding segment.

4. The method as claimed in claim 1 , further comprising assigning a main control unit to the control units substantially automatically in dependence on the identified strand guiding segments by at least one of setting of operating parameters and by selection of a computer-readable program code.

5. The method as claimed in claim 4 , further comprising:
basing the strand guiding system on an open-loop control or a closed-loop control of the strand guiding system by determining open-loop or closed-loop control signals of the strand guiding system depending upon the identified strand guiding segments;
determining setpoint values for the open-loop control or the closed-loop control of at least one of setting positions of the strand guiding rollers and setting forces of the settable strand guide rollers;
determining the setting forces or the setting positions of the strand guide rollers by use of a simulation model comprised of a computer-readable program code on a processor unit of the main control unit; and
using the respective determined setpoint value to determine a manipulated value for at least one of the setting positions and the setting forces and using the determined manipulated value by means of the open-loop or closed-loop control signals for influencing at least one of the setting positions and the setting forces of the settable strand guiding rollers.

6. The method as claimed in claim 5 , wherein one of the closed-loop control elements is assigned to a strand guiding roller of a strand guiding segment assigned to one of the control units.

7. The method as claimed in claim 1 , further comprising configuring the strand guiding system after at least one of demounting and mounting of a strand guiding segment from or into the strand guiding system.

8. A strand guiding system comprising:
a plurality of strand guiding segments, each strand guiding segment configured for guiding a respective metallic strand, each strand guiding segment has at least one of a software coding and a hardware coding for identification thereof, and a plurality of control units,
wherein one of the control units is respectively assigned to each strand guiding segment and is configured for controlling the strand guiding segment by transmission of an open-loop or a closed-loop control signal;
the control units are configured for identification of the strand guiding segment respectively assigned thereto by use of at least one of the software coding and the hardware coding of the respective strand guiding segment; and
each control unit has a configuration that is configured to be adapted substantially automatically, in dependence on the identified strand guiding segment, by at least one of setting of operating parameters and by selection of a computer-readable program code,
wherein each strand guiding segment comprises a storage unit comprising at least one of an RFID storage element and a RAM storage module configured to store the software coding.

9. The strand guiding system as claimed in claim 8 , wherein the hardware coding comprises a mechanical element of a segment-specific plug connection.

10. The strand guiding system as claimed in claim 8 , wherein each control unit comprises a plurality of closed-loop control elements, wherein each closed-loop control element is respectively assigned to a strand guiding roller of the strand guiding segment assigned to the respective control unit,
wherein the strand guiding roller is set individually against the strand.

11. The strand guiding system as claimed in claim 8 , further comprising a main control unit assigned to the control units and connected to the control units via a network connection,
wherein the main control unit controls the control units by transmission of a respective setpoint value signal for forming open-loop or closed-loop control signals.

12. The strand guiding system as claimed in claim 11 , further comprising:
the main control unit is configured to identify the strand guiding segments indirectly assigned thereto; and
has a configuration that is adapted substantially automatically, in dependence on the identified strand guiding segments, by at least one of setting of operating parameters and by selection of a computer-readable program code.

13. The strand guiding system of claim 8 , further comprising a plurality of the control units which are substantially the same are assigned to strand guiding segments of differing structural types.

14. A strand guiding system comprising:
a plurality of strand guiding segments, each strand guiding segment configured to guide a respective metallic strand, each strand guiding segment has at least one of a software coding and a hardware coding for identification thereof, and a plurality of control units,
wherein one of the control units is respectively assigned to each strand guiding segment and is configured to control the strand guiding segment by transmission of an open-loop or a closed-loop control signal;
the control units are configured to identify the strand guiding segment respectively assigned thereto by use of at least one of the software coding and the hardware coding of the respective strand guiding segment; and
each control unit has a configuration that is configured to be adapted substantially automatically, in dependence on the identified strand guiding segment, by at least one of setting of operating parameters and by selection of a computer-readable program code,
wherein each control unit comprises a plurality of closed-loop control elements, wherein each closed-loop control element is respectively assigned to a strand guiding roller of the strand guiding segment assigned to the respective control unit, and
wherein the strand guiding roller is set individually against the strand.

15. A strand guiding system comprising:
a plurality of strand guiding segments, each strand guiding segment configured to guide a respective metallic strand, each strand guiding segment has at least one of a software coding and a hardware coding for identification thereof, and a plurality of control units,
wherein one of the control units is respectively assigned to each strand guiding segment and is configured to control the strand guiding segment by transmission of an open-loop or a closed-loop control signal;
the control units are configured to identify the s
