Abstract
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
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.It is to dissipate the heat generated during the continuous casting of metals known to install a mold tube in a water jacket. Here is for it Care that due to the inner dimensions of the water jacket on the one hand and the outer dimensions of the mold tube on the other thermally precisely defined gap is formed by the bottom Cooling water flows above, which absorbs the heat and transports it away. If a mold tube in beam blank format is used, the inner contour must also be used correspond 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 dissipation of heat by means of the cooling water is largely due to the water speed in the gap between the mold tube and the water jacket certainly. However, this gap increases with each recalibration Chill pipe due to wear-related wear and tear inevitably caused reduction in the wall thickness of a mold tube. The Increasing the water gap is, however, with a reduction in the water speed and consequently associated with a reduction in 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 use molds for the continuous casting of metals To provide cooling holes, which are both in the longitudinal direction and in Extend the transverse direction of the mold tube. For mold tubes in beam blank format However, there is the problem that cooling bores cross to Longitudinal extension can only be introduced into the mold tubes with great effort can. In addition, the special geometry of the beam blank format creates extreme local heat loads in the transitions between one side Flange area and on the other hand wall sections delimiting a web area. This local heat load leads to unfavorable geometric conditions the transitions to overheating the mold tube and to a drastic one 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.Based on the prior art, the invention is based on the object To provide mold tube for the continuous casting of metals, which improved Has service life and at which local overheating is avoided.
Eine erste Lösung der Aufgabe besteht in den Merkmalen des Patentanspruchs 1.A first solution to the problem consists in the features of
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
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 is initially associated with the advantage that one on the outer contour Pipe mold to be adapted water guiding jacket can basically be omitted. This Significant reduction in production costs is particularly the case with one Mold tube in a beam blank format is noticeable.
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.The heat is dissipated via the cooling channels in the pipe wall changing heat dissipation conditions 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 ducts can in principle be used in all wall sections on the end faces emerge from the pipe wall. In these areas it is easy to install and secure sealing of a mold tube after recalibration without any problems possible to carry out welds, which are then easy after recalibration reworked to new dimensions.
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, the result is further advantage after bending a tube mold to a beam blank format, that the cross sections of many cooling channels are also oval shaped, namely in the sense that the surface areas increase towards the pouring channel, so that a higher heat dissipation can be expected.
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 solution consists in the features of
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 also possible according to the features of
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 can differ from the upper one Face of the pipe wall up to about the middle height range of the pipe wall extend. This is thermally strong for a more intensive heat dissipation in locally claimed wall sections worried (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
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 fundamentally possible to supply the cooling medium and coolant discharge to a separate cooling circuit to join. But that can be advantageous between the tube wall and the Coolant flowing through the water guiding jacket also flows through the cooling channels and for intensive heat dissipation in areas subject to higher thermal stress (Claim 7). To keep the coolant from entering the gap between the Water guiding jacket and the pipe wall in the cooling ducts can be facilitated at the The outer contour of the pipe wall and / or the water guide jacket suitable guide means be provided, the flow of the cooling medium into the cooling channels to steer.
Die erfindungsgemäßen Merkmale machen sich besonders vorteilhaft bei einem Kokillenrohr mit einem Doppel-T-förmigen Querschnitt nach Patentanspruch 8 bemerkbar.The features according to the invention are particularly advantageous for one 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.
