Definitions
- the invention relates to a cooling device for cooling a metallic item, in particular a metal strip.
- the invention also relates to a method for operating a corresponding cooling device.

- the cooling device has nozzles for applying a coolant to the metallic material, the nozzles being arranged distributed over the width. At least one of the nozzles can be adjusted in its position with respect to the width of the metallic material. This means that it is possible to influence non-uniform temperature distributions over the width of the metal strip to a limited extent. A subdivision of the cooling bar into individual spray areas is not known from this patent.
- the subdivision of a cooling bar into individual spray areas is, for example, from the European patent EP 2 986 400 B1 known.
- the cooling device disclosed there has at least one cooling beam which extends transversely to the transport direction of the metallic goods when they pass through the cooling device.
- the at least one cooling beam has - in its longitudinal direction, that is to say transversely to the transport direction of the metallic good - two outer and one central spray area arranged between the two outer spray areas.
- each of the spray areas can be individually controlled via specially assigned Valves are fed a cooling medium, which is then applied to the metallic material to be cooled via the spray nozzles assigned to the respective spray area.
- the invention is based on the object of developing a known cooling device and a known method for its operation in such a way that the application of coolant to the metallic goods is improved and the starting point of a degressive decrease or a positive increase in the volume flow of the coolant is variable along the longitudinal extent of the cooling beam becomes determinable.
- At least one partition is provided in the at least one cooling beam of the cooling device according to the invention for dividing the interior of the cooling beam into at least two chambers, each of the spray areas being assigned to a different one of the chambers.
- the partition is shaped at least approximately according to the course of the temperature distribution in a predetermined width section of the metallic material before it enters the cooling device, and the partition wall is arranged in the cooling beam over this width section.
- the cooling device comprises at least one control element - also controllable by the control device - for the variable positioning of the partition walls within the cooling bar, in particular for moving the partition walls in the longitudinal direction of the cooling bar, and thus for changing the chambers and the spray areas of one cooling bar in each case
- the claimed division of the interior of the cooling beam into a plurality of chambers with the help of partition walls and in particular the claimed special shape of the partition walls according to the course of the temperature distribution over the width of the goods to be cooled advantageously enables particularly effective and targeted cooling of the goods.
- the cooling can be adapted particularly well to the actual cooling requirement across the width of the goods. In this way, constant, degressive or progressive cooling strategies can advantageously be implemented over the width of the goods to be cooled.
- the starting point of a degressive decrease or a positive increase in the volume flow of the coolant along the longitudinal extension of the cooling bar can be variably determined and suitably adapted to cooling requirements in individual cases.

- At least one of the spraying areas has a plurality of spray nozzles distributed over the area of the spraying area, preferably arranged in parallel rows in the longitudinal direction of the cooling bar, this offers the advantage that over the width of the item to be cooled there are also curved or curved distributions of the coolant discharge are possible which run relatively smoothly, d. H. do not have excessive jumps or discontinuities in the transition between individual subsections of the distribution.
- At least three chambers are formed in a cooling beam, ie a left, a middle and a right spray area, because the Edge areas of the goods to be cooled generally require less cooling than the middle area of the goods to be cooled.
- the cooling device can have a plurality of cooling bars arranged in parallel, which are each arranged above or below the item to be cooled.
- Such a group-wise combination of several chilled beams offers the advantage that the distribution of the coolant over the width of the goods is even smoother, i. H. can be implemented without jumps or pronounced kinks in the volume flow of the coolant.
- the control device can be designed either in the form of a pilot control or in the form of a regulating device. In both cases, it is used to achieve a pre-calculated target distribution of the coolant across the width of the metal item. In both cases, the volume flow or the pressure of the coolant can be used by suitable setting of the valves and / or the actuators for positioning the partition walls to generate the respectively desired target distribution of the coolant over the goods to be cooled.
- the target distributions of the volume flow or the pressure of the coolant over the width of the goods to be cooled are preferably calculated using a cooling model. This applies both to the design of the control device in the form of a pilot control and to its design in the form of a regulating device.

- valves 120 can be seen by way of example for individually setting the pressure or the volume flow of the coolant in each of the spray areas I, II, III.
- the coolant 300 is fed individually from a coolant tank with the aid of a pump 160 through the valves 120 into the individual spray areas I, II, III.
- a control device 150 is provided for the individual control of the pump 160 and the valves 120.
- two partition walls 140 are provided for dividing the cooling bar 110 into three chambers or three spray areas I, II, III.
- the three areas are designed symmetrically; this means that an equal number of spray nozzles is allocated to the middle spray area II to the right and left of the center in particular.
- Figure 1 shows the temperature distribution of the goods, typically measured with the help of a temperature determination device, over its width before entering the cooling device or before entering under the cooling beam 110.
- the partition walls are shaped in a width section ⁇ Y1, ⁇ Y2 corresponding to the temperature profile over the same width section ⁇ Y1, ⁇ Y2 .
- Figure 2 shows a second embodiment for dividing the cooling bar 110 into individual chambers and spray areas, here five spray areas I, II, III, IV and V. Accordingly, five valves 120 are provided for individually feeding the coolant 300 into the individual chambers or spray areas .
- the arrangement or the number of spray nozzles 130 relative to the center M of the metallic material asymmetrically. This can be seen in particular from the fact that more spray nozzles 130 are arranged in the right half of the central spray area III than in its left part.
- the partition walls 140 each run between the spray nozzles 130.
- the partition walls are step-shaped; alternatively, however, they can also be designed to run straight or arcuate, in particular parabolic.
- the partition walls are shaped exactly in accordance with the temperature distribution in a corresponding width section. In practice, it is often sufficient to approximate the shape of the partition walls to the temperature distribution, for example by means of the step or staircase function or a straight line.
- the number of chambers or spray areas per cooling beam is basically arbitrary. The more chambers or spray areas that are implemented, the more precisely a desired distribution for the coolant over the width of the product can be set.
- control device can be designed in the form of a pilot control for suitable setting of the valves 120 and / or the actuators 144 for positioning the partition walls with regard to setpoint values, in particular a calculated or predetermined setpoint distribution for the coolant 300 over the metallic material .

- the individual data or parameters or setpoints mentioned are to be understood as merely exemplary. This means that for the calculation of certain setpoints it is not absolutely necessary that all of the input variables mentioned as examples on the input side of the cooling model have to be used.
- Figure 4 shows a selection of different temperature profiles over the width of the goods to be cooled before they enter the cooling device 100 according to the invention qualitative representation of exemplary useful cooling strategies.
- the dashed curve profile denotes the temperature profile of the metallic material before it enters the cooling device.
- the solid line shown above is characteristic of the distribution according to the invention of the coolant within the cooling device for treating the incoming temperature profile.
- top and middle figures in Figure 4 require a symmetrical distribution of the coolant, which goes hand in hand with a symmetrical division of the spray areas along the length of the cooling bar and a symmetrical arrangement of the spray nozzles and preferably also a symmetrical arrangement of the spray nozzles within the spray areas, as shown in the lower figure in Figure 4 an asymmetrical temperature and coolant curve.
- the temperature at the left edge area shows no difference to the center of the goods, while the temperature in the right edge area has dropped significantly.
- the coolant distribution required for this in the left edge area must be almost constant or unchanged compared to the central area of the goods to be cooled, while the output of the coolant volume flow at the right edge must be significantly reduced.
- FIG. 8 shows an exemplary embodiment of the present invention in which the partition walls 140 can be moved in the longitudinal direction of the cooling bar 110.
- a movement of the partition walls 140 causes a shift in the starting time for the Beginning of a degressive course of the coolant distribution.
- the right and left partition walls 140 in the in Figure 5 the embodiment shown move outwards (see dashed line); This has the consequence that the starting times for the degressive decrease in the coolant volume flow are shifted to the right and left to the outside, ie towards the edges of the metallic material.

Description
Die Erfindung betrifft eine Kühleinrichtung zum Kühlen eines metallischen Gutes, insbesondere eines Metallbandes. Die Erfindung betrifft darüber hinaus ein Verfahren zum Betreiben einer entsprechenden Kühleinrichtung.The invention relates to a cooling device for cooling a metallic item, in particular a metal strip. The invention also relates to a method for operating a corresponding cooling device.
Kühleinrichtungen dieser Art sind im Stand der Technik hinlänglich bekannt, so beispielsweise aus den europäischen Patentschriften
Die europäische Patentschrift
Die Unterteilung eines Kühlbalkens in einzelne Spritzbereiche ist jedoch beispielsweise aus der europäischen Patentschrift
Die japanische Patentanmeldung
Der Erfindung liegt die Aufgabe zugrunde, eine bekannte Kühleinrichtung sowie ein bekanntes Verfahren zu deren Betrieb dahingehend weiterzubilden, dass die Beaufschlagung des metallischen Gutes mit Kühlmittel verbessert und der Startpunkt eines degressiven Abfalls bzw. eines positiven Anstieges des Volumenstroms des Kühlmittels entlang der Längserstreckung des Kühlbalkens variabel festlegbar wird.The invention is based on the object of developing a known cooling device and a known method for its operation in such a way that the application of coolant to the metallic goods is improved and the starting point of a degressive decrease or a positive increase in the volume flow of the coolant is variable along the longitudinal extent of the cooling beam becomes determinable.
Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst. Demnach ist bei dem mindestens einen Kühlbalken der erfindungsgemäßen Kühleinrichtung mindestens eine Trennwand vorgesehen ist zum Unterteilen des Innenraums des Kühlbalkens in mindestens zwei Kammern, wobei jeder der Spritzbereiche einer anderen der Kammern zugeordnet ist. Die Trennwand ist zumindest näherungsweise entsprechend dem Verlauf der Temperaturverteilung in einem vorbestimmten Breitenabschnitt des metallischen Gutes vor Einlauf in die Kühleinrichtung geformt und die Trennwand ist in dem Kühlbalken über diesem Breitenabschnitt angeordnet. Weiterhin umfasst die Kühleinrichtung mindestens ein - ebenfalls von der Steuereinrichtung ansteuerbares - Steuerelement zum variablen Positionieren der Trennwände innerhalb des Kühlbalkens, insbesondere zum Verfahren der Trennwände in Längsrichtung des Kühlbalkens, und damit zum Verändern der Kammern und der Spritzbereiche jeweils eines KühlbalkensThis object is achieved by the subject matter of claim 1. Accordingly, at least one partition is provided in the at least one cooling beam of the cooling device according to the invention for dividing the interior of the cooling beam into at least two chambers, each of the spray areas being assigned to a different one of the chambers. The partition is shaped at least approximately according to the course of the temperature distribution in a predetermined width section of the metallic material before it enters the cooling device, and the partition wall is arranged in the cooling beam over this width section. Furthermore, the cooling device comprises at least one control element - also controllable by the control device - for the variable positioning of the partition walls within the cooling bar, in particular for moving the partition walls in the longitudinal direction of the cooling bar, and thus for changing the chambers and the spray areas of one cooling bar in each case
Die beanspruchte Unterteilung des Innenraums des Kühlbalkens in eine Mehrzahl von Kammern mit Hilfe von Trennwänden sowie insbesondere die beanspruchte spezielle Formgebung der Trennwände entsprechend dem Verlauf der Temperaturverteilung über der Breite des zu kühlenden Gutes ermöglicht vorteilhafterweise eine besonders effektive und gezielte Kühlung des Gutes. Insbesondere durch die beanspruchte Formgebung der Trennwände, vorzugsweise in Verbindung mit einer unterschiedlichen Einspeisung von Kühlmittel in die durch die Trennwand separierten Kammern, kann die Kühlung besonders gut an den tatsächlichen Kühlbedarf über der Breite des Gutes angepasst werden. Vorteilhafterweise können so konstante, degressive oder progressive Kühlstrategien über der Breite des zu kühlenden Gutes realisiert werden.The claimed division of the interior of the cooling beam into a plurality of chambers with the help of partition walls and in particular the claimed special shape of the partition walls according to the course of the temperature distribution over the width of the goods to be cooled advantageously enables particularly effective and targeted cooling of the goods. In particular by the claimed shape of the partition walls, preferably in conjunction with a different supply of coolant into the chambers separated by the partition wall, the cooling can be adapted particularly well to the actual cooling requirement across the width of the goods. In this way, constant, degressive or progressive cooling strategies can advantageously be implemented over the width of the goods to be cooled.
Durch diese beanspruchte Verfahrbarkeit der Trennelemente kann insbesondere der Startpunkt eines degressiven Abfalls bzw. eines positiven Anstieges des Volumenstroms des Kühlmittels entlang der Längserstreckung des Kühlbalkens variabel festgelegt und geeignet an Kühlerfordernisse im Einzelfall angepasst werden. Der Startpunkt kann bezogen auf die Breite des zu kühlenden Gutes symmetrisch auf beiden Seiten oder alternativ auch asymmetrisch nur auf einer Seite des zu kühlenden Gutes verstellt werden, je nach Temperaturprofil des in die Kühleinrichtung einlaufenden metallischen Gutes.As a result of this claimed movability of the separating elements, in particular the starting point of a degressive decrease or a positive increase in the volume flow of the coolant along the longitudinal extension of the cooling bar can be variably determined and suitably adapted to cooling requirements in individual cases. The starting point can be adjusted symmetrically on both sides based on the width of the goods to be cooled or, alternatively, asymmetrically only on one side of the goods to be cooled, depending on the temperature profile of the metallic goods entering the cooling device.
Wenn gemäß einem ersten Ausführungsbeispiel zumindest einer der Spritzbereiche eine Mehrzahl von Spritzdüsen aufweist, die über die Fläche des Spritzbereiches verteilt, vorzugsweise in parallelen Reihen in Längsrichtung des Kühlbalkens verlaufend angeordnet sind, bietet das den Vorteil, dass über der Breite des zu kühlenden Gutes auch bogenförmige bzw. gekrümmte Verteilungen der Kühlmittel-Ausbringung möglich sind, die relativ glatt verlaufen, d. h. keine allzu starken Sprünge bzw. Unstetigkeitsstellen im Übergang zwischen einzelnen Teilabschnitten der Verteilung aufweisen.If, according to a first exemplary embodiment, at least one of the spraying areas has a plurality of spray nozzles distributed over the area of the spraying area, preferably arranged in parallel rows in the longitudinal direction of the cooling bar, this offers the advantage that over the width of the item to be cooled there are also curved or curved distributions of the coolant discharge are possible which run relatively smoothly, d. H. do not have excessive jumps or discontinuities in the transition between individual subsections of the distribution.
Bezogen auf die Mitte des zu kühlenden metallischen Gutes kann es vorteilhaft sein, die Anordnung und/oder die Anzahl der Spritzdüsen in den Spritzbereichen symmetrisch oder asymmetrisch zu wählen, je nach Temperaturprofil des in die Kühleinrichtung einlaufenden Gutes, wobei das Temperaturprofil jeweils in geeigneter Weise abzuändern ist.In relation to the center of the metallic material to be cooled, it can be advantageous to choose the arrangement and / or the number of spray nozzles in the spraying areas symmetrically or asymmetrically, depending on the temperature profile of the material entering the cooling device, with the temperature profile being modified in a suitable manner is.
Vorteilhafterweise sind bei einem Kühlbalken mindestens drei Kammern ausgebildet, d. h. ein linker, ein mittlerer und ein rechter Spritzbereich, weil die Randbereiche des zu kühlenden Gutes in der Regel eine weniger starke Kühlung benötigen als der mittlere Bereich des zu kühlenden Gutes.Advantageously, at least three chambers are formed in a cooling beam, ie a left, a middle and a right spray area, because the Edge areas of the goods to be cooled generally require less cooling than the middle area of the goods to be cooled.
Die Kühleinrichtung kann eine Mehrzahl von parallel angeordneten Kühlbalken aufweisen, die jeweils oberhalb oder unterhalb des zu kühlenden Gutes angeordnet sind. Eine solche gruppenweise Zusammenfassung mehrerer Kühlbalken bietet den Vorteil, dass die Verteilung des Kühlmittels über der Breite des Gutes noch glatter, d. h. ohne Sprünge oder stark ausgeprägte Knicke im Volumenstrom des Kühlmittels realisiert werden kann.The cooling device can have a plurality of cooling bars arranged in parallel, which are each arranged above or below the item to be cooled. Such a group-wise combination of several chilled beams offers the advantage that the distribution of the coolant over the width of the goods is even smoother, i. H. can be implemented without jumps or pronounced kinks in the volume flow of the coolant.
Die Steuereinrichtung kann entweder in Form einer Vorsteuerung oder in Form einer Regeleinrichtung ausgebildet sein. In beiden Fällen dient sie dazu, eine vorberechnete Soll-Verteilung des Kühlmittels über der Breite des metallischen Gutes zu realisieren. In beiden Fällen kann der Volumenstrom oder der Druck des Kühlmittels durch geeignetes Einstellen der Ventile und/oder können die Stellglieder zum Positionieren der Trennwände verwendet werden zum Generieren der jeweils gewünschten Soll-Verteilung des Kühlmittels über dem zu kühlenden Gut. Die Soll-Verteilungen des Volumenstromes oder des Druckes des Kühlmittels über der Breite des zu kühlenden Gutes werden vorzugsweise mit einem Kühlmodell berechnet. Dies gilt sowohl für die Ausbildung der Steuereinrichtung in Form einer Vorsteuerung wie auch für deren Ausbildung in Form einer Regeleinrichtung.The control device can be designed either in the form of a pilot control or in the form of a regulating device. In both cases, it is used to achieve a pre-calculated target distribution of the coolant across the width of the metal item. In both cases, the volume flow or the pressure of the coolant can be used by suitable setting of the valves and / or the actuators for positioning the partition walls to generate the respectively desired target distribution of the coolant over the goods to be cooled. The target distributions of the volume flow or the pressure of the coolant over the width of the goods to be cooled are preferably calculated using a cooling model. This applies both to the design of the control device in the form of a pilot control and to its design in the form of a regulating device.
Die oben genannte Aufgabe der Erfindung wird weiterhin gelöst durch ein erfindungsgemäßes Verfahren nach Anspruch 14. Die Vorteile dieses Verfahrens entsprechen den oben in Bezug auf die beanspruchte Vorrichtung genannten Vorteilen.The above-mentioned object of the invention is further achieved by a method according to the invention according to claim 14. The advantages of this method correspond to the advantages mentioned above with regard to the claimed device.
Das Verfahren der Trennwände kann außerhalb oder während eines laufenden Kühlbetriebs erfolgen.The partition walls can be moved outside or during ongoing cooling operations.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Kühleinrichtung und des erfindungsgemäßen Verfahrens zu deren Betrieb sind Gegenstand der abhängigen Ansprüche.Further advantageous configurations of the cooling device according to the invention and the method according to the invention for its operation are the subject matter of the dependent claims.
