Definitions

  • the metal strand emerges vertically downwards from the continuous casting mold and is gradually diverted to the horizontal later on. This situation is usually also present within the scope of the present invention. However, it is of secondary importance in the sense of the invention. It is important, however, that the term "withdrawal direction" does not mean a direction that is once determined and then unchangeable over the entire strand guide, but always locally the direction in which the cast metal strand is currently moving. The withdrawal direction can therefore depend on the location within the strand guide. At a certain location, the withdrawal direction is of course constant over time.
  • the cutting device can be designed as a flame cutting machine or as a hydraulic shear, as required, both in the prior art and within the scope of the present invention.
  • the cutting point is the location along the strand guide where the separation of the respective section begins.
  • the present invention is further based on a control device for at least one separating device of a continuous casting plant of a plant in the metal industry, wherein the control device is programmed with such a control program so that it carries out such an operating method during operation.
  • the cast metal strand emerges from the continuous casting mold with an already solidified strand shell and a still liquid core. It is cooled intensively in the subsequent strand guide and gradually solidifies until it is completely solidified. After complete solidification, sections of the cast metal strand are often separated and then further processed, for example fed directly or indirectly to a rolling mill.
  • a casting and rolling plant is operated in continuous operation.
  • the cutting location i.e. the location where the separating device is located and where the separation of the respective section begins.
  • the cutting location is determined in such a way that the metal strand is completely solidified at the cutting location even if the metal strand is withdrawn from the continuous casting mold at the maximum possible withdrawal speed.
  • the maximum possible withdrawal speed is determined by the design of the continuous casting plant, in particular the casting format.
  • the continuous casting plant is operated at the maximum possible withdrawal speed (or slightly below this). However, this is not always possible. For example, disruptions in the casting process can occur which require the withdrawal speed to be reduced.
  • a disruption is a shell stick, which must be eliminated in good time before a strand breakage occurs.
  • disruptions can also occur in downstream processes.
  • An example of a planned "disruption" is a roll change in a rolling stand of a rolling mill downstream of the continuous casting plant.
  • An unplanned disruption is, for example, a walkover when threading a rolled stock into a rolling stand. Even in the event of disruptions, casting as such is maintained - as far as possible. However, the withdrawal speed must be reduced.
  • Reducing the withdrawal speed means that the place where the core has completely solidified, i.e. the metal strand has completely solidified, migrates towards the continuous casting mold. Furthermore, this means that the cast metal strand has already cooled down considerably when it reaches the cutting point in the current technology. This means that high forces or large amounts of energy are required to separate the respective section from the cast metal strand. Subsequent processes, such as rolling in a downstream rolling mill or heating up before rolling in the rolling mill, are also adversely affected. If a casting and rolling plant is operated in continuous operation, it may also be necessary to switch from continuous operation to batch operation. In some circumstances, it may even be possible that separation is no longer possible at all, resulting in the casting being aborted.
  • the further separating device is arranged in front of the first-mentioned separating device in the withdrawal direction. Depending on the operating conditions of the continuous casting plant, one or the other separating device is operated.
  • the object of the present invention is to provide possibilities by means of which the disadvantages of the prior art can be avoided in a simple manner.
  • the control device therefore always positions the separating device according to the cutting location known to it for the respective separating process.
  • the cutting location is determined, if possible, in such a way that the cutting location - if necessary while maintaining a safety distance - is as close as possible to the solidification location.
  • the solidification location is the location of the sump tip of the liquid core.
  • control device It is possible for the control device to receive the respective cutting location from an operator before each separation.
  • the specification is made as required as an absolute value ("move the cutting device to the specified position") or by specifying travel commands ("continue to move as long as the operator wishes"). This procedure is particularly simple.
  • control device it is possible for the control device to know a solidification location within the strand guide (5) before each separation, at which the cast metal strand has completely solidified, and for the control device to determine the cutting location depending on from the solidification location.
  • the solidification location can be known to the control device, for example, through a specification by the operator.
  • control device determines the solidification location based on operating data of the continuous casting plant known to the control device. This procedure is particularly flexible.
  • the operating data that can be used include the casting format (width and thickness of the cast metal strand) and the withdrawal speed. If necessary, the extent to which the cast metal strand is cooled in the strand guide may also be relevant.
  • the control device determines the solidification location by modeling the solidification behavior of the cast metal strand. In particular, when determining the solidification location, the control device takes into account the period of time during which the individual areas of the cast metal strand are cooled.
  • the severed section is transported further by means of the strand guide from the point of separation from the cast metal strand at a transport speed which is greater than the withdrawal speed. This minimizes the time it takes to reach the next processing station.
  • the severed section can therefore be fed to the next treatment facility with relatively low thermal losses.
  • the metal industry plant includes a rolling mill arranged in line with the strand guide, the severed sections of the metal strand can in particular be fed to the rolling mill and rolled in the rolling mill using the casting heat.
  • the metal industry plant is therefore not designed as a pure continuous casting plant, but as a casting and rolling plant. If necessary, a furnace can be arranged between the strand guide and the rolling mill.
  • control device During the separation of the respective section of the metal strand, the control device often moves the cutting device by a cutting path in the pull-off direction, starting from the cutting location.
  • the extent to which the control device moves the cutting device during the cutting of the respective section of the metal strand, i.e. the cutting path, is quite small.
  • the cutting path is usually in the lower single-digit meter range, for example in the case of hydraulic shears in the range between 1 m and 2 m and in the case of a flame cutting machine between 2 m and 4 m.
  • the possible travel path within which the control device can position the cutting device is, however, larger than the cutting path, often even considerably larger.
  • the possible travel path satisfies the condition that the possible travel path is at least three times, preferably at least five times and particularly preferably at least ten times as large as the cutting path and/or is at least 10 m and preferably at least 25 m.
  • even larger values are also possible, for example 20 times, 30 times or an even larger multiple of the cutting path. or a possible travel distance of 50 m, 80 m or 100 m.
  • the numerical values given are purely exemplary.
  • the cast metal strand is guided on at least one side (namely at the bottom) by transport rollers of the strand guide.
  • transport rollers are usually only attached to the cast metal strand on the underside of the cast metal strand.
  • those transport rollers of the strand guide that are located between an initial location, where the separating device is located before positioning at the cutting location, and the cutting location are retracted from the metal strand during positioning of the separating device and then reattached to the metal strand. This results in considerable structural simplifications of the strand guide.
  • the retraction and re-attachment can be carried out individually for the respective transport roller or in groups for several transport rollers at a time.
  • the retraction and repositioning of the transport rollers can be implemented as required.
  • corresponding actuators can be assigned to the transport rollers.
  • the actuators can be controlled in particular by the control device.
  • the actuators can be designed as hydraulic cylinders, for example.
  • the transport rollers can be pivotably mounted and for counterweights to apply a force that causes them to be deflected upwards until they either hit stationary stops on the strand guide or the cast metal strand.
  • the separating device or a carriage on which the separating device is arranged can, for example, have a guide rail that temporarily deflects the transport rollers downwards from their raised position.
  • control program with the features of claim 9.
  • An advantageous embodiment of the control program is the subject of dependent claim 10.
  • the processing of the machine code by the control device also causes the control device to carry out the method steps of at least one of the advantageous embodiments of the operating method explained above.
  • the advantages achieved in each case correspond, as before, to those of the operating method.
  • control device with the features of claim 11.
  • the control device is programmed with a control program according to the invention, so that the control device executes an operating method according to the invention during operation.
  • a rolling mill of the metal industry plant is arranged downstream of the strand guide, whereby the separated sections of the metal strand can be fed to the rolling mill by means of the strand guide and can be rolled by the rolling mill from the casting heat.
  • This means that the separated sections can be fed to the rolling mill immediately after separation with little temperature loss and can be rolled there.
  • the possible travel path is advantageously at least 10 m and preferably at least 25 m. Furthermore, the separating device is generally moved by one cutting path in the withdrawal direction starting from the cutting location during the separation of the respective section of the metal strand. In this case, the possible travel path is advantageously greater than, preferably at least three times as large as, particularly preferably at least five times and in particular at least ten times as large as the cutting path. This increases the flexibility when operating the plant in the metal industry.
  • the strand guide usually has transport rollers for transporting the cast metal strand and/or the separated sections.
  • those transport rollers that are located within the possible travel path are designed as transport rollers that can be retracted from the metal strand and then placed back onto the metal strand. This design leads to a considerable structural simplification in the design of the strand guide, in particular the implementation of the movable separating device.

  • the plant in the metal industry can have further components in addition to the continuous casting plant 1. This will become clear from later explanations.
  • the continuous casting plant 1 in turn has a continuous casting mold 2.
  • Liquid metal 3 is fed to the continuous casting mold 2 from above.
  • the liquid metal 3 is cast into a metal strand 4 by means of the continuous casting mold 2.
  • the feeding of the liquid metal 3 is generally known to experts and is of secondary importance within the scope of the present invention. It is therefore not explained in more detail.
  • the liquid metal 3 can be, for example, liquid steel or liquid aluminum. Other metals or metal alloys are also possible.
  • the strand shell 6 surrounds a core 7 of the metal strand.
  • the core 7 is initially still liquid and gradually solidifies while the metal strand 4 passes through the strand guide 5.

  • the transport rollers 9 can surround the metal strand 4 on several sides.
  • the metal strand 4 is often arranged as shown in FIG 1 initially cast vertically and then gradually deflected to the horizontal. As long as the metal strand 4 is guided essentially vertically and also during deflection to the horizontal, the metal strand 4 is generally supported on both sides by the transport rollers 9. After deflection to the horizontal, it is possible that the metal strand 4 is only supported on its underside by the transport rollers 9. Alternatively, it is possible that the metal strand 4 is also supported in this area on both its top and bottom by the transport rollers 9.

  • the metal industry plant also has a control device 14.
  • the control device 14 controls at least the separating device 10. It therefore outputs control signals C to the separating device 10. Furthermore, the control device 14 can also receive information from the separating device 10 or other components and also from outside. This is in FIG 1 not shown for reasons of clarity.

  • step S4 the control device 14 controls the separating device 10 in such a way that the separating device 10 separates the section 11 to be separated from the cast metal strand 4.

From step S4, the control device 14 returns to step S1.
