Description

Die Erfindung betrifft ein Kokillenrohr zum Stranggießen von Metallen gemäß den Merkmalen im Oberbegriff des Patentanspruchs 1.The invention relates to a mold tube for the continuous casting of metals according to the features in the preamble of patent claim 1.

Zum Abführen der beim Stranggießen von Metallen anfallenden Wärme ist es bekannt, ein Kokillenrohr in einen Wasserleitmantel einzubauen. Hierbei ist dafür Sorge getragen, daß aufgrund der Innenabmessungen des Wasserleitmantels einerseits und der Außenabmessungen des Kokillenrohrs andererseits ein wärmetechnisch genau definierter Spalt gebildet wird, durch den von unten nach oben Kühlwasser fließt, welches die anfallende Wärme aufnimmt und abtransportiert. Wird ein Kokillenrohr im Beam-Blank-Format eingesetzt, so muß auch die Innenkontur des Wasserleitmantels der Außenkontur eines solchen Formats entsprechen.To dissipate the heat generated during the continuous casting of metals, it is known to install a mold tube in a water-conducting jacket. In this case, care is taken that due to the inner dimensions of the Wasserleitmantels one hand, and the outer dimensions of the Kokillenrohrs on the other hand, a thermally well-defined gap is formed through which flows from bottom to top cooling water, which absorbs the heat accumulated and transported away. If a mold tube in the beam blank format used, so must the inner contour of the water jacket corresponding to the outer contour of such a format.

Die Abfuhr der Wärme mittels des Kühlwassers wird weitgehend durch die Wassergeschwindigkeit im Spalt zwischen dem Kokillenrohr und dem Wasserleitmantel bestimmt. Dieser Spalt vergrößert sich jedoch bei jeder Rekalibrierung eines Kokillenrohrs aufgrund der verschleißbedingten Abnutzung und der dadurch zwangsläufig hervorgerufenen Reduzierung der Wanddicke eines Kokillenrohrs. Die Vergrößerung des Wasserspalts ist indessen mit einer Reduktion der Wassergeschwindigkeit und folglich auch mit einer Reduzierung der Wärmeabfuhr verbunden.The removal of heat by means of the cooling water is largely determined by the water velocity in the gap between the mold tube and the Wasserleitmantel. However, this gap increases with each recalibration of a Kokillenrohrs due to the wear-related wear and thereby inevitably caused reduction in the wall thickness of a Kokillenrohrs. The enlargement of the water gap is, however, associated with a reduction of the water velocity and consequently also with a reduction of the heat dissipation.

Aus der GB 954 719 ist es bekannt, Kokillen zum Stranggießen von Metallen mit Kühlbohrungen zu versehen, die sich sowohl in Längsrichtung als auch in Querrichtung des Kokillenrohrs erstrecken. Bei Kokillenrohren im Beam-Blank-Format ergibt sich allerdings das Problem, daß Kühlbohrungen quer zur Längserstreckung nur mit großem Aufwand in die Kokillenrohre eingebracht werden können. Zudem entstehen bei der speziellen Geometrie des Beam-Blank-Formats extreme lokale Wärmebelastungen in den Übergängen zwischen einerseits einen Flanschbereich und andererseits einen Stegbereich begrenzenden Wandabschnitten. Diese lokale Wärmebelastung führt bei ungünstigen geometrischen Verhältnissen der Übergänge zu einer Überhitzung des Kokillenrohrs und zu einer drastischen Reduzierung seiner Standzeit.From GB 954 719 it is known to provide molds for the continuous casting of metals with cooling holes which extend both in the longitudinal direction and in the transverse direction of the mold tube. In mold tubes in the beam blank format, however, the problem arises that cooling holes can be introduced transversely to the longitudinal extent only with great effort in the mold tubes. In addition, with the special geometry of the beam-blank format, extreme local heat loads occur in the transitions between, on the one hand, a flange region and, on the other hand, a wall region delimiting wall regions. In the case of unfavorable geometrical conditions of the transitions, this local heat load leads to overheating of the mold tube and to a drastic reduction of its service life.

Die Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, ein Kokillenrohr zum Stranggießen von Metallen zu schaffen, das eine verbesserte Standzeit besitzt und bei welchem lokale Überhitzungen vermieden werden.The invention is - based on the prior art - the object of the invention to provide a mold tube for the continuous casting of metals, which has an improved life and in which local overheating be avoided.

Eine erste Lösung der Aufgabe besteht in den Merkmalen des Patentanspruchs 1.A first solution of the problem consists in the features of patent claim 1.

Nach den Merkmalen des Patentanspruchs 1 ist jetzt der Abstand von zwei in den Übergängen einander benachbarter Kühlkanäle kleiner als der Abstand benachbarter Kühlkanäle in den übrigen Wandabschnitten.According to the features of claim 1, the distance between two adjacent cooling channels in the transitions is smaller than the distance between adjacent cooling channels in the other wall sections.

Hiermit ist zunächst der Vorteil verbunden, daß ein an die Außenkontur einer Rohrkokille anzupassender Wasserleitmantel grundsätzlich entfallen kann. Diese deutliche Reduzierung des Fertigungsaufwands macht sich insbesondere bei einem Kokillenrohr in einem Beam-Blank-Format bemerkbar.This initially has the advantage that a to be matched to the outer contour of a tube mold water jacket can be omitted in principle. This significant reduction of the manufacturing effort is particularly noticeable in the case of a mold tube in a beam blank format.

Durch die Abfuhr der Wärme über die Kühlkanäle in der Rohrwand entstehen keine sich verändernden Wärmeabfuhrbedingungen mehr. Die Anzahl der Rekalibrierungen ist ohne Einfluß auf die Kühlleistung.By dissipating the heat through the cooling channels in the pipe wall, no changing heat removal conditions arise more. The number of recalibrations has no influence on the cooling capacity.

Die Kühlkanäle können grundsätzlich in allen Wandabschnitten an den Stirnseiten der Rohrwand austreten. In diesen Bereichen ist es für ein problemloses Einbauen und eine sichere Abdichtung eines Kokillenrohrs nach der Rekalibrierung problemlos möglich, auch Schweißungen durchzuführen, die dann nach der Rekalibrierung einfach auf Neumaß nachbearbeitet werden.The cooling channels can basically emerge in all wall sections on the end faces of the pipe wall. In these areas, it is easily possible for a trouble-free installation and a secure sealing of a mold tube after recalibration to perform welds, which are then post-recalibrated easily to Neumaß.

Wenn die Kühlkanäle mit einem runden Querschnitt versehen werden, ergibt sich der weitere Vorteil nach dem Biegen einer Rohrkokille zu einem Beam-Blank-Format, daß hierbei auch die Querschnitte vieler Kühlkanäle oval verformt werden, und zwar in dem Sinne, daß sich die Oberflächenbereiche zum Gießkanal hin vergrößern, so daß mit einer höheren Wärmeabfuhr gerechnet werden kann.If the cooling channels are provided with a round cross section, there is the further advantage after bending a tube mold to a beam blank format, that in this case also the cross sections of many cooling channels are deformed oval, in the sense that the surface areas for Enlarge pouring channel, so that can be expected with a higher heat dissipation.

Eine zweite Lössung besteht in den Merkmalen des Patentanspruchs 2. Danach ist es auch möglich, nur in den gerundeten Übergängen Kühlkanäle vorzusehen, während die übrigen Wandabschnitte sowie die gerundeten Übergänge über einen an die Außenkontur der Rohrwand angepaßten Wasserleitmantel kühlbar sind. Bei dieser Lösung ist nicht die gesamte Rohrwand mit Kühlkanälen durchsetzt. Vielmehr sind ausschließlich in den Bereichen Kühlbohrungen vorhanden, in denen lokale Überhitzungen zu einer Verringerung der Standzeit des Kokillenrohrs führen würden. Durch die Kombination eines Wasserleitmantels mit in die gerundeten Übergänge der Rohrwand eingebrachten Kühlkanälen können lokale Überhitzungen in den gerundeten Übergängen vermieden und die Standzeit des Kokillenrohrs erhöht werden.A second Lössung consists in the features of claim 2. Thereafter, it is also possible to provide cooling channels only in the rounded transitions, while the remaining wall sections and the rounded transitions are cooled by a matched to the outer contour of the pipe wall Wasserleitmantel. In this solution, not the entire pipe wall is interspersed with cooling channels. Rather, cooling holes are present only in the areas in which local overheating would lead to a reduction in the service life of the mold tube. By combining a water jacket with introduced into the rounded transitions of the pipe wall cooling channels local overheating in the rounded transitions can be avoided and the life of the mold tube can be increased.

Es ist nach den Merkmalen des Patentanspruchs 3 auch möglich, einen Wasserleitmantel und gleichzeitig sowohl in den gerundeten Übergängen als auch in den übrigen Wandabschnitten der Rohrwand Kühlbohrungen vorzusehen, wobei der Abstand von zwei in den Übergängen einander benachbarten Kühlkanälen kleiner ist als der Abstand in den übrigen Wandabschnitten.It is according to the features of claim 3 also possible to provide a Wasserleitmantel and at the same time both in the rounded transitions and in the other wall sections of the pipe wall cooling holes, wherein the distance of two mutually adjacent in the transitions cooling channels is smaller than the distance in the rest wall sections.

Die in den Übergängen vorgesehenen Kühlkanäle können sich von der oberen Stirnseite der Rohrwand bis etwa zum mittleren Höhenbereich der Rohrwand erstrecken. Hierdurch wird für eine intensivere Wärmeabfuhr in lokal thermisch stark beanspruchten Wandabschnitten gesorgt (Patentanspruch 4).The cooling channels provided in the transitions may extend from the upper end side of the pipe wall to approximately the middle height region of the pipe wall. As a result, a more intensive heat dissipation in locally thermally stressed wall sections provided (claim 4).

Nach Patentanspruch 5 ist vorgesehen, daß in der Außenkontur der Rohrwand an die Kühlkanäle angeschlossene Kühlmediumzuführungen und Kühlmediumabführungen vorgesehen sind. Diese können besonders vorteilhaft im mittleren Höhenbereich an der Außenkontur der Rohrwand vorgesehen sein (Patentanspruch 6). Zur Ausbildung eines Kühlkanalsystems werden die von den Stirnseiten der Rohrwände her eingebrachten Kühlkanäle verschlossen und durch Überströmkanäle miteinander verbunden.According to claim 5, it is provided that in the outer contour of the pipe wall connected to the cooling channels Kühlmediumzuführungen and Kühlmediumabführungen are provided. These can be particularly advantageously provided in the middle height range on the outer contour of the pipe wall (claim 6). To form a cooling channel system, the cooling channels introduced from the end faces of the tube walls are closed and connected to one another by overflow channels.

Zur Kühlung des Kokillenrohrs ist es grundsätzlich möglich, die Kühlmediumzuführungen und Kühlmediumabführungen an einen separaten Kühlkreislauf anzuschließen. Vorteilhaft kann aber das zwischen der Rohrwand und dem Wasserleitmantel strömende Kühlmedium auch die Kühlkanäle durchströmen und für eine intensive Wärmeabfuhr in thermisch höher beanspruchten Bereichen sorgen (Patentanspruch 7). Um den Kühlmitteleintritt aus dem Spalt zwischen dem Wasserleitmantel und der Rohrwand in die Kühlkanäle zu erleichtern, können an der Außenkontur der Rohrwand und/oder dem Wasserleitmantel geeignete Leitmittel vorgesehen sein, die den Strömungsverlauf des Kühlmediums in die Kühlkanäle lenken.To cool the mold tube, it is basically possible to connect the cooling medium supply and cooling medium discharges to a separate cooling circuit. Advantageously, however, the cooling medium flowing between the pipe wall and the water-conducting jacket can also flow through the cooling channels and ensure intensive heat dissipation in areas subjected to higher thermal stresses (claim 7). In order to facilitate the coolant inlet from the gap between the Wasserleitmantel and the pipe wall in the cooling channels, suitable conductive means may be provided on the outer contour of the pipe wall and / or the Wasserleitmantel, which direct the flow of the cooling medium in the cooling channels.

Die erfindungsgemäßen Merkmale machen sich besonders vorteilhaft bei einem Kokillenrohr mit einem Doppel-T-förmigen Querschnitt nach Patentanspruch 8 bemerkbar.The features of the invention are particularly advantageous in a mold tube with a double-T-shaped cross section according to claim 8 noticeable.

Das Kokillenrohr besteht vorzugsweise aus Kupfer oder einer Kupferlegierung.The mold tube is preferably made of copper or a copper alloy.

Die Erfindung ist nachfolgend anhand eines in den Zeichnungen veranschaulichten Ausführungsbeispiels näher erläutert. Es zeigen:

The invention is explained in more detail with reference to an embodiment illustrated in the drawings. Show it:

FIG. 2
the mold tube of Figure 1 in a slightly extended view in a different perspective and
FIG. 3
the upper end portion of a mold tube in the beam blank format according to another embodiment.

Mit 1 ist in den Figuren 1 und 2 ein Kokillenrohr im Beam-Blank-Format bezeichnet.1, a mold tube in the beam blank format is designated in FIGS. 1 and 2.

Das Kokillenrohr 1 weist einen Doppel-T-förmigen Querschnitt auf mit einer über den gesamten Umfang gleichbleibenden Dicke D der Rohrwand 2.The mold tube 1 has a double-T-shaped cross-section with a constant over the entire circumference thickness D of the tube wall. 2

Die Innenkontur 3 des Kokillenrohrs 1 bestimmt den Querschnitt des Gießstrangs.The inner contour 3 of the mold tube 1 determines the cross section of the cast strand.

Um die beim Gießen anfallende Wärme abzuführen, sind in die Rohrwand 2 sich über die gesamte Länge L des Kokillenrohrs 1 erstreckende Kühlkanäle 4 eingebracht, welche gemäß dem Pfeil KW von unten nach oben mit Kühlwasser beaufschlagbar sind. Das heißt die Kühlkanäle 4 enden in den Stirnseiten 5 der Rohrwand 2, wobei nur die eine Stirnseite 5 erkennbar ist.In order to dissipate the heat generated during casting, 1 cooling channels 4 are provided in the tube wall 2 extending over the entire length L of the mold tube 1, which are acted upon in accordance with the arrow KW from bottom to top with cooling water. That is, the cooling channels 4 terminate in the end faces 5 of the tube wall 2, wherein only one end face 5 can be seen.

Die Kühlkanäle 4 werden durch eine Bohroperation in die Rohrwand 2 eingebracht, und zwar bevor das Kokillenrohr 1 gebogen wird. Durch das Biegen können sich die Kühlkanäle 4 teilweise dann so oval verformen, daß zur Innenkontur 3 hin größere Oberflächenbereiche gebildet werden, wodurch die Wärmeabfuhr verbessert wird.The cooling channels 4 are introduced by a Bohroperation in the pipe wall 2, and that before the mold tube 1 is bent. By bending the cooling channels 4 can then partially deform so oval that the inner contour 3 towards larger surface areas are formed, whereby the heat dissipation is improved.

Die spezielle Innenkontur 3 des Kokillenrohrs 1 besitzt gerundete Übergänge 6 zwischen einerseits einen Flanschbereich 7 und andererseits einen Stegbereich 8 begrenzenden Wandabschnitten 9. Der Abstand A von zwei in den Übergängen 6 einander benachbarten Kühlkanälen 4 ist kleiner als der Abstand B in den übrigen Wandabschnitten 9.The specific inner contour 3 of the mold tube 1 has rounded transitions 6 between a flange region 7 on the one hand and a wall region 9 delimiting a web region 8 on the other hand. The distance A between two cooling passages 4 adjacent to one another in the transitions 6 is smaller than the distance B in the remaining wall sections 9.

Während bei den Ausführungsbeispielen der Figuren 1 und 2 die Kühlkanäle 4 die Kokillenrohre 1 über ihre gesamte Länge L durchsetzen, ist es auch denkbar, daß sich die in den Übergängen 6 vorgesehenen Kühlkanäle 4 von der oberen Stirnseite 5 der Rohrwand 2 bis etwa zum mittleren Höhenbereich der Rohrwand 2 erstrecken. Diese Kühlkanäle 4 können zur Ausbildung eines Kühlkreislaufs an ihren oberen Stirnseiten miteinander verbunden sein und über Kühlmediumzuführungen und Kühlmediumabführungen im mittleren Höhenbereich der Rohrwand 2 mit einem Kühlmedium gespeist werden.While in the embodiments of Figures 1 and 2, the cooling channels 4, the Kokillenrohre 1 enforce over its entire length L, it is also conceivable that provided in the transitions 6 cooling channels 4 from the upper end face 5 of the pipe wall 2 to about the middle height range the pipe wall 2 extend. These cooling channels 4 can be connected to one another to form a cooling circuit at their upper end sides and fed via Kühlmediumzuführungen and Kühlmediumabführungen in the middle height range of the pipe wall 2 with a cooling medium.

Zusätzlich kann das Kokillenrohr 1 in einen an die Außenkontur 10 der Rohrwand 2 angepaßten Wasserleitmantel eingebettet sein, so daß das Kokillenrohr 1 insgesamt von einem mit einem Kühlmedium durchströmten Kühlspalt umgeben ist.In addition, the mold tube 1 may be embedded in a matched to the outer contour 10 of the pipe wall 2 Wasserleitmantel, so that the mold tube 1 is surrounded in total by a flow-through with a cooling medium cooling gap.

Figur 3 zeigt in einer etwas anderen Perspektive eine weitere Ausführungsform eines Kokillenrohrs 11 mit einer Innenkontur 12 im Beam-Blank-Format, ebenfalls mit gerundeten Übergängen 13 zwischen einerseits einen Flanschbereich 14 und andererseits einen Stegbereich 15 begrenzenden Wandabschnitten 16. Bei diesem Ausführungsbeispiel sind Kühlbohrungen 4 nur in den Übergangsbereichen 13 vorhanden. Das gesamte Kokillenrohr 11 ist in nicht näher dargestellter Weise in einen an die Außenkontur 17 der Rohrwand 18 angepaßten Wasserleitmantel eingebettet, über den sowohl die übrigen Wandabschnitte 16 als auch die mit Kühlbohrungen 4 versehenen Übergangsbereiche 13 gekühlt werden.FIG. 3 shows, in a somewhat different perspective, another embodiment of a mold tube 11 with an inner contour 12 in the beam blank format, likewise with rounded transitions 13 between, on the one hand, a flange region 14 and, on the other hand, a web region 15 delimiting wall sections 16 Embodiment cooling holes 4 are present only in the transition areas 13. The entire mold tube 11 is embedded in a manner not shown in a matched to the outer contour 17 of the tube wall 18 Wasserleitmantel over which both the remaining wall portions 16 and provided with cooling holes 4 transition areas 13 are cooled.
