Definitions
- the invention relates to a mold for the continuous casting of metal with the features of the preamble of claim 1.
- Tubular molds of copper or copper alloys for casting profiles of steel and other high melting point metals have been widely described in the art.
- the mold tubes are cooled by cooling water, which flows through a water gap between the inside of the wall of a surrounding the mold tube water box and the outside of the mold tube.
- the mold tube is oriented by way of adjusting screws in the water box so that adjusts the desired width of the water gap on the circumferential side of the mold tube. Since the mold tube is subject to extreme thermal stresses, the exact alignment of the mold tube in the water box must be done very carefully so that it does not come due to different widths of the water gap at different flow velocities and thus to a different degree of heat dissipation. This would result in a different strand shell growth and different degrees of shrinkage. This in turn can lead to material tensions and cracks in the strand shell, which increases the risk of strand penetration.
- the invention has the object to show a liquid-cooled mold for continuous casting of metal, in which the complex orientation of the mold is simplified within the water box.
- the solution is seen in a mold with the features of claim 1.
- Advantageous embodiments of the inventive concept are the subject of the dependent claims.
- the mold according to the invention it is provided that at least one water baffle is arranged in the water gap.
- the water guide plate leads to cross-sectional changes of the water gap, the cross-sectional changes resulting in a change in the flow velocity. Since the mold tube is mounted freely displaceable relative to the water tank at least in one direction, the working position of the mold tube can be adjusted by the flow conditions in the water gap itself. As a result, the mold tube is self-centering in the water box orientation. Self-centering is achieved by balancing the hydrodynamic forces in the water gap. If, for example, the width of the water gap on one side of the mold tube becomes greater, the flow velocity drops in this area. The hydrodynamic force acting on the outer wall of the mold tube also decreases in this area.
- the water guide plate is arranged in the region of the cooling grooves.
- the flow cross section in the area of the cooling grooves increases, which leads to a reduction in the flow velocity.
- the water guide plate at least partially reduces the flow cross section in the region of the cooling grooves.
- the water baffle has an end-side bypass section, which is designed such that cooling water is directed from the water gap targeted into the cooling grooves.
- the bypass section is configured in a streamlined manner, so that as far as possible no turbulence forms in the coolant gap.
- the diverting section is configured arcuate.
- the flow velocity in the inflow and outflow region of the cooling grooves is increased by the water guide plate.
- the local increases in the flow velocities also lead to an increase in the hydrodynamic forces in this area. It is favorable if the regions of increased flow velocity are arranged diametrically at the same height of the mold tube. Preferably, therefore, all Wasserleitbleche are configured identically.
- Figure 1 shows a mold tube 1 rectangular cross-section, which is placed in a water tank, not shown.
- the mold tube 1 is liquid-cooled from the outside, wherein between the inside of the wall of the channel box and the outside 2 of the mold tube 1, a water gap is formed.
- the Wasserleitbleche 3 shown are arranged.
- the Wasserleitbleche 3 are clearly visible in their spatial arrangement in the perspective view of Figure 2.
- four Wasserleitbleche 3 are provided, with always two Wasserleitbleche 3 are opposite to the same height.
- the water guide plates 3 are identically configured and extend almost over the entire width of a side wall 5 of the mold tube 1, wherein the corner regions 6 are recessed.
- a partial region of the outer sides 2 of the mold tube is provided with a cooling groove 7 extending in the flow direction.
- the cooling grooves 7 do not extend over the entire length of the mold tube 1, but only in the region of the G fauxLitesolllage, since the largest heat flux densities occur and a correspondingly intensive cooling of the mold tube 1 is required.
- the cooling grooves 7 lead to an enlargement of the cooling surface, so that the heat transfer is facilitated in the cooling water.
- the water guide plates 3 are placed in the region of the cooling grooves 7, wherein the water guide plates 3 are somewhat shorter than the cooling grooves 7. That is, the cooling grooves 7 protrude below the water guide plate 3 both in their inflow and outflow regions.
- a guide groove 8 can be seen at the upper end 4 of the mold tube 1, via which the mold tube 1 is held in the vertical direction on the water tank, not shown.
- the guide groove 8 is configured so that a displacement transverse to the flow direction of the cooling water is possible.
- the Wasserleitbleche 3 are rectangularly configured and have a flat central portion 9, which at each end, ie seen in the flow direction Umleitabitese 10, 11 connect.
- the Umleitabitese 10, 11 are issued in the direction of the mold 1 and are configured arcuately.
- the diverting sections 10, 11 are identical, that is trough-shaped.
- the exact contour or the radius of the channel-shaped sections is preferably matched to the depth profile of the cooling grooves 7.
- the cooling grooves 7 preferably have a radius in the inflow and outflow region in order to avoid turbulence in the cooling water flow when entering the cooling grooves 7. This radius can also be used in the curved diverting sections.

Abstract
Description
Die Erfindung betrifft eine Kokille zum Stranggießen von Metall mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a mold for the continuous casting of metal with the features of the preamble of claim 1.
Rohrförmige Kokillen aus Kupfer oder Kupferlegierungen zum Gießen von Profilen aus Stahl und anderen Metallen mit hohem Schmelzpunkt sind vielfach im Stand der Technik beschrieben worden. Die Kokillenrohre werden dabei durch Kühlwasser gekühlt, das einen Wasserspalt zwischen der Innenseite der Wandung eines das Kokillenrohr umgebenden Wasserkastens und der Außenseite des Kokillenrohrs durchströmt. Üblicherweise wird das Kokillenrohr über Einstellschrauben derart in dem Wasserkasten lageorientiert, dass sich umfangsseitig des Kokillenrohrs die gewünschte Breite des Wasserspalts einstellt. Da das Kokillenrohr extremen thermischen Belastungen unterliegt, muss die exakte Ausrichtung des Kokillenrohrs im Wasserkasten sehr sorgfältig erfolgen, damit es nicht aufgrund unterschiedlicher Breiten des Wasserspalts zu unterschiedlichen Strömungsgeschwindigkeiten und damit zu einem unterschiedlich starken Wärmeabfluss kommt. Dies hätte ein unterschiedliches Strangschalenwachstum und unterschiedlich starke Schrumpfungen zur Folge. Dies kann wiederum zu Materialspannungen und Rissen in der Strangschale führen, wodurch sich das Risiko eines Strangdurchbruches erhöht.Tubular molds of copper or copper alloys for casting profiles of steel and other high melting point metals have been widely described in the art. The mold tubes are cooled by cooling water, which flows through a water gap between the inside of the wall of a surrounding the mold tube water box and the outside of the mold tube. Usually, the mold tube is oriented by way of adjusting screws in the water box so that adjusts the desired width of the water gap on the circumferential side of the mold tube. Since the mold tube is subject to extreme thermal stresses, the exact alignment of the mold tube in the water box must be done very carefully so that it does not come due to different widths of the water gap at different flow velocities and thus to a different degree of heat dissipation. This would result in a different strand shell growth and different degrees of shrinkage. This in turn can lead to material tensions and cracks in the strand shell, which increases the risk of strand penetration.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine flüssigkeitsgekühlte Kokille zum Stranggießen von Metall aufzuzeigen, bei welcher die aufwendige Ausrichtung der Kokille innerhalb des Wasserkastens vereinfacht wird. Die Lösung wird in einer Kokille mit den Merkmalen des Patentanspruchs 1 gesehen. Vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand der Unteransprüche.Proceeding from this, the invention has the object to show a liquid-cooled mold for continuous casting of metal, in which the complex orientation of the mold is simplified within the water box. The solution is seen in a mold with the features of claim 1. Advantageous embodiments of the inventive concept are the subject of the dependent claims.
Bei der erfindungsgemäßen Kokille ist vorgesehen, dass in dem Wasserspalt wenigstens ein Wasserleitblech angeordnet ist. Das Wasserleitblech führt zu Querschnittsveränderungen des Wasserspalts, wobei die Querschnittsveränderungen in einer Veränderung der Strömungsgeschwindigkeit resultieren. Da das Kokillenrohr zumindest in eine Richtung frei verschiebbar gegenüber dem Wasserkasten gelagert ist, kann sich die Arbeitslage des Kokillenrohrs durch die Strömungsverhältnisse im Wasserspalt selbst einstellen. Dadurch wird das Kokillenrohr selbstzentrierend in dem Wasserkasten lageorientiert. Die Selbstzentrierung wird dadurch erreicht, dass sich die hydrodynamischen Kräfte im Wasserspalt gegenseitig ausgleichen. Wird die Breite des Wasserspalts auf einer Seite des Kokillenrohrs beispielsweise größer, sinkt in diesem Bereich die Strömungsgeschwindigkeit. Die hydrodynamische Kraft, die auf die Außenwand des Kokillenrohrs wirkt, sinkt in diesem Bereich ebenfalls. Im gleichen Maß führt die Reduzierung der Breite des Wasserspalts auf der gegenüberliegenden Seite des Kokillenrohrs zu einer Erhöhung der Strömungsgeschwindigkeit, wodurch sich in diesem Bereich höhere hydrodynamische Kräfte einstellen, die sich aufgrund des seitlich frei verschiebbaren Kokillenrohrs dahingehend auswirken, dass das Kokillenrohr geringfügig verschoben wird, bis sich wieder ein Kräftegleichgewicht ergibt. Die Wasserleitbleche sind daher in sich jeweils gegenüber liegenden Bereichen des Kokillenrohrs bzw. des Wasserspalts angeordnet.In the mold according to the invention it is provided that at least one water baffle is arranged in the water gap. The water guide plate leads to cross-sectional changes of the water gap, the cross-sectional changes resulting in a change in the flow velocity. Since the mold tube is mounted freely displaceable relative to the water tank at least in one direction, the working position of the mold tube can be adjusted by the flow conditions in the water gap itself. As a result, the mold tube is self-centering in the water box orientation. Self-centering is achieved by balancing the hydrodynamic forces in the water gap. If, for example, the width of the water gap on one side of the mold tube becomes greater, the flow velocity drops in this area. The hydrodynamic force acting on the outer wall of the mold tube also decreases in this area. To the same extent, the reduction of the width of the water gap on the opposite side of the mold tube leads to an increase in the flow velocity, which sets higher hydrodynamic forces in this area, which have an effect due to the laterally freely displaceable mold tube in that the mold tube is slightly displaced. until there is an equilibrium of forces again. The Wasserleitbleche are therefore arranged in each opposite areas of the mold tube or the water gap.
Insbesondere wird es als zweckmäßig angesehen, wenn zumindest ein Teilbereich der Außenfläche des Kokillenrohrs mit Kühlnuten versehen ist, wobei das Wasserleitblech im Bereich der Kühlnuten angeordnet ist. Bei einem Wasserspalt konstanten Querschnitts vergrößert sich der Strömungsquerschnitt im Bereich der Kühlnuten, was zu einer Reduzierung der Strömungsgeschwindigkeit führt. Um Kühlwasser mit hoher Geschwindigkeit durch die Kühlnuten zu führen, ist vorgesehen, dass das Wasserleitblech den Strömungsquerschnitt im Bereich der Kühlnuten zumindest bereichsweise verkleinert. Hierfür besitzt das Wasserleitblech einen endseitigen Umleitabschnitt, welcher derart ausgebildet ist, dass Kühlwasser aus dem Wasserspalt gezielt in die Kühlnuten geleitet wird. Der Umleitabschnitt ist strömungsgünstig konfiguriert, so dass sich möglichst keine Verwirbelungen im Kühlmittelspalt bilden. Zweckmäßigerweise ist der Umleitabschnitt bogenförmig konfiguriert.In particular, it is considered expedient if at least a portion of the outer surface of the mold tube is provided with cooling grooves, wherein the water guide plate is arranged in the region of the cooling grooves. In the case of a water gap of constant cross section, the flow cross section in the area of the cooling grooves increases, which leads to a reduction in the flow velocity. In order to guide cooling water through the cooling grooves at high speed, it is provided that the water guide plate at least partially reduces the flow cross section in the region of the cooling grooves. For this purpose, the water baffle has an end-side bypass section, which is designed such that cooling water is directed from the water gap targeted into the cooling grooves. The bypass section is configured in a streamlined manner, so that as far as possible no turbulence forms in the coolant gap. Conveniently, the diverting section is configured arcuate.
Gemäß der Ausführungsform des Patentanspruchs 6 wird die Strömungsgeschwindigkeit im Einström- und Ausströmbereich der Kühlnuten durch das Wasserleitblech erhöht. Die lokalen Erhöhungen der Strömungsgeschwindigkeiten führen auch zu einem Anstieg der hydrodynamischen Kräfte in diesem Bereich. Es ist günstig, wenn die Bereiche erhöhter Strömungsgeschwindigkeit diametral auf gleicher Höhe des Kokillenrohrs angeordnet sind. Vorzugsweise sind daher sämtliche Wasserleitbleche identisch konfiguriert.According to the embodiment of claim 6, the flow velocity in the inflow and outflow region of the cooling grooves is increased by the water guide plate. The local increases in the flow velocities also lead to an increase in the hydrodynamic forces in this area. It is favorable if the regions of increased flow velocity are arranged diametrically at the same height of the mold tube. Preferably, therefore, all Wasserleitbleche are configured identically.
Die Erfindung wird nachfolgend anhand des in den Figuren 1 und 2 schematisch dargestellten Ausführungsbeispiels näher erläutert. Figur 1 zeigt ein Kokillenrohr 1 rechteckigen Querschnitts, das in einem nicht näher dargestellten Wasserkasten platziert wird. Das Kokillenrohr 1 wird von außen flüssigkeitsgekühlt, wobei zwischen der Innenseite der Wandung des Wasserkastens und der Außenseite 2 des Kokillenrohrs 1 ein Wasserspalt ausgebildet wird. In diesem Wasserspalt werden die dargestellten Wasserleitbleche 3 angeordnet.The invention will be explained in more detail with reference to the embodiment shown schematically in Figures 1 and 2. Figure 1 shows a mold tube 1 rectangular cross-section, which is placed in a water tank, not shown. The mold tube 1 is liquid-cooled from the outside, wherein between the inside of the wall of the channel box and the outside 2 of the mold tube 1, a water gap is formed. In this water gap the
Die Wasserleitbleche 3 sind in ihrer räumlichen Anordnung in der perspektivischen Darstellung der Figur 2 gut zu erkennen. Bei diesem Ausführungsbeispiel sind vier Wasserleitbleche 3 vorgesehen, wobei sich immer zwei Wasserleitbleche 3 auf gleicher Höhe gegenüber liegen. Die Wasserleitbleche 3 sind identisch konfiguriert und erstrecken sich nahezu über die gesamte Breite einer Seitenwand 5 des Kokillenrohrs 1, wobei die Eckbereiche 6 ausgespart werden.The Wasserleitbleche 3 are clearly visible in their spatial arrangement in the perspective view of Figure 2. In this embodiment, four
In Figur 1 ist zu erkennen, dass ein Teilbereich der Außenseiten 2 des Kokillenrohrs mit einer sich in Strömungsrichtung erstreckenden Kühlnut 7 versehen ist. Die Kühlnuten 7 erstrecken sich nicht über die gesamte Länge des Kokillenrohrs 1, sondern ausschließlich im Bereich der Gießspiegelsolllage, da hier die größten Wärmestromdichten auftreten und eine entsprechend intensive Kühlung des Kokillenrohrs 1 erforderlich ist. Die Kühlnuten 7 führen zu einer Vergrößerung der Kühlfläche, so dass der Wärmeübergang in das Kühlwasser erleichtert wird. Im Bereich der Kühlnuten 7 sind die Wasserleitbleche 3 platziert, wobei die Wasserleitbleche 3 etwas kürzer sind als die Kühlnuten 7. Das heißt, die Kühlnuten 7 ragen sowohl in ihrem Einström- als auch in ihrem Ausströmbereich unter dem Wasserleitblech 3 hervor. Des weiteren ist in Figur 1 eine Führungsnut 8 am oberen Ende 4 des Kokillenrohrs 1 zu erkennen, über welche das Kokillenrohr 1 in Hochrichtung an dem nicht näher dargestellten Wasserkasten gehalten ist. Die Führungsnut 8 ist so konfiguriert, dass eine Verlagerung quer zur Strömungsrichtung des Kühlwassers möglich ist.It can be seen in FIG. 1 that a partial region of the
Die Wasserleitbleche 3 sind rechteckig konfiguriert und besitzen einen ebenen Mittelabschnitt 9, an welchen sich jeweils endseitig, das heißt in Strömungsrichtung gesehen Umleitabschnitte 10, 11 anschließen. Die Umleitabschnitte 10, 11 sind in Richtung zur Kokille 1 ausgestellt und sind dabei bogenförmig konfiguriert. In diesem Ausführungsbeispiel sind die Umleitabschnitte 10, 11 identisch, das heißt rinnenförmig ausgebildet. Die genaue Kontur bzw. der Radius der rinnenförmigen Abschnitte ist bevorzugt auf den Tiefenverlauf der Kühlnuten 7 abgestimmt. Die Kühlnuten 7 besitzen im Ein- und Ausströmbereich vorzugsweise einen Radius, um Verwirbelungen im Kühlwasserstrom beim Eintritt in die Kühlnuten 7 zu vermeiden. Dieser Radius kann auch bei den bogenförmigen Umleitabschnitten verwendet werden.The
