Description

Die Erfindung betrifft ein Kokillenrohr mit einem Doppel-T-förmigen Innen- und Außenquerschnitt im Beam-Blank-Format gemäß den Merkmalen im Oberbegriff des Patentanspruchs 1.The invention relates to a mold tube with a double-T-shaped inner and outer cross-section in the beam blank format according to the features in the preamble of patent claim 1.

Beim Stranggießen von Metallen mit einem Kokillenrohr ergeben sich die Materialtemperaturen in der Kokillenwand aus den beim Stranggießen auftretenden Wärmebelastungen und den Kühlbedingungen durch das jeweilige Kühlmedium, was in aller Regel in Form von Wasser in einem Wasserspalt zwischen einem an die Außenkontur des Kokillenrohrs angepaßten Wasserleitmantel und der äußeren Oberfläche des Kokillenrohrs von unten nach oben strömt, hierbei die anfallende Wärme aufnimmt und abtransportiert. Die Abfuhr der Wärme mittels Kühlwasser wird weitgehend durch die Wassergeschwindigkeit im Wasserspalt bestimmt.In the continuous casting of metals with a mold tube, the material temperatures in the mold wall resulting from the heat loads occurring during continuous casting and the cooling conditions by the respective cooling medium, which usually in the form of water in a water gap between a matched to the outer contour of the mold tube Wasserleitmantel and the outside surface of the Kokillenrohrs flows from bottom to top, this absorbs the heat accumulated and transported away. The removal of heat by means of cooling water is largely determined by the water velocity in the water gap.

Beim Stranggießen von Metallen mit einem Kokillenrohr der in Rede stehenden Gattung hat man beobachtet, daß aufgrund der speziellen Geometrie des Beam-Blank-Formats extreme lokale Wärmebelastungen in den Übergangsbereichen von den einander frontal gegenüber liegenden, zur Längsachse hin eingezogenen mittleren Stegen auf die angrenzenden schräg gestellten Flansche auftreten. Diese lokalen Wärmebelastungen führen bei ungünstigen geometrischen Verhältnissen der Übergangsbereiche zu einer Überhitzung des Kokillenrohrs und demzufolge zu einer drastischen Reduzierung seiner Standzeit.In the continuous casting of metals with a mold tube of the type in question it has been observed that due to the special geometry of the beam blank format extreme local heat loads in the transition areas of the frontally opposite, retracted to the longitudinal axis center webs on the adjacent oblique Asked flanges occur. These local heat loads lead in unfavorable geometric conditions of the transition areas to overheating of the mold tube and consequently to a drastic reduction in its life.

Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, ein Kokillenrohr mit einem Doppel-T-förmigen Innen- und Außenquerschnitt im Beam-Blank-Format zum Stranggießen von Metallen zu schaffen, bei welchem eine lokale Überhitzung der Übergangsbereiche vermieden und dadurch eine längere Standzeit erzielt wird.The invention is - based on the prior art - the object of the invention to provide a mold tube with a double-T-shaped inner and outer cross section in the beam blank format for continuous casting of metals, in which a local overheating of the transition areas avoided and thereby a longer life is achieved.

Diese Aufgabe wird mit den im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmalen gelöst.This object is achieved with the features stated in the characterizing part of patent claim 1.

Durch die zumindest partielle Reduzierung der Wanddicke des Kokillenrohrs in den gerundeten Übergangsbereichen wird hier eine deutlich verbesserte Wärmeabfuhr erreicht, damit eine lokale Überhitzung der Übergangsbereiche vermieden und folglich die Standzeit des Kokillenrohrs deutlich heraufgesetzt.Due to the at least partial reduction of the wall thickness of the mold tube in the rounded transition areas a significantly improved heat dissipation is achieved here, thus avoiding local overheating of the transition areas and consequently significantly increases the service life of the mold tube.

Im Hinblick darauf, daß beim Stranggießen von Metallen die höchste Wärmebelastung im Kokillenrohr in der Regel im Höhenbereich des Badspiegels auftritt, sehen die Merkmale des Patentanspruchs 2 vor, daß die Wanddicke in den Übergangsbereichen nur im Höhenbereich des Badspiegels reduziert ist.In view of the fact that in the continuous casting of metals, the highest heat load in the mold tube usually occurs in the height range of the bathroom mirror, the features of claim 2 provide that the wall thickness is reduced in the transition areas only in the height range of the bathroom mirror.

Die Reduzierung der Wanddicke des Kokillenrohrs in den gerundeten Übergangsbereichen kann auf verschiedene Art und Weise erfolgen.The reduction of the wall thickness of the mold tube in the rounded transition areas can be done in various ways.

Entsprechend den Merkmalen des Patentanspruchs 3 sind außenseitig der Übergangsbereiche längs gerichtete muldenförmige Aussparungen vorgesehen. Die Krümmung der Aussparungen kann hierbei weitgehend an die Krümmung der inneren Oberfläche der Übergangsbereiche angepaßt sein. Außerdem hat die Wanddickenreduzierung in Form von muldenförmigen Aussparungen den Vorteil, daß die äußere Oberfläche des Kokillenrohrs vergrößert wird, so daß ein noch besserer Kühleffekt erreichbar ist.According to the features of claim 3 outside of the transition areas longitudinally directed trough-shaped recesses are provided. The curvature of the recesses in this case can be largely adapted to the curvature of the inner surface of the transition regions. In addition, the wall thickness reduction in the form of trough-shaped recesses has the advantage that the outer surface of the mold tube is increased, so that an even better cooling effect can be achieved.

Eine weitere Möglichkeit der Wanddickenreduzierung wird in den Merkmalen des Patentanspruchs 4 erblickt. Danach sind außenseitig der Übergangsbereiche mehrere längs gerichtete, nebeneinander verlaufende Nuten vorgesehen. Der Querschnitt und/oder die Tiefe der Nuten kann in jedem Übergangsbereich gleich oder unterschiedlich bemessen sein. Der Querschnitt der Nuten kann gerundet oder eckig, z.B. dreieckförmig sein.Another way of reducing wall thickness is seen in the features of claim 4. Thereafter, on the outside of the transition regions a plurality of longitudinally directed, adjacent grooves are provided. The cross-section and / or the depth of the grooves may be the same or different in each transition region. The cross section of the grooves may be rounded or angular, e.g. be triangular.

Ferner ist es entsprechend den Merkmalen des Patentanspruchs 5 denkbar, daß zur Wanddickenreduzierung in den Wandabschnitten der Übergangsbereiche mehrere längs gerichtete, nebeneinander verlaufende Bohrungen vorgesehen sind. Die Größe der Bohrungen, ihre Anzahl, der Abstand zueinander und auch ihre Lage in Relation zur Außen- bzw. Innenkontur des Kokillenrohrs kann variieren. Vorteilhaft ist es jedoch, wenn die Bohrungen eine größere Nähe zur äußeren Oberfläche als zur inneren Oberfläche des Kokillenrohrs haben.Further, it is conceivable according to the features of claim 5, that a plurality of longitudinally directed, side by side extending bores are provided to reduce the wall thickness in the wall portions of the transition regions. The size of the holes, their number, the distance from each other and also their position in relation to the outer or inner contour of the Kokillenrohrs may vary. It is advantageous, however, if the holes have a greater proximity to the outer surface than to the inner surface of the mold tube.

Da die Abfuhr der Wärme mittels Kühlwasser - wie bekannt - durch die Wassergeschwindigkeit im Wasserspalt zwischen dem Kokillenrohr und dem Wasserleitmantel bestimmt wird, sollte dieser Wasserspalt auch im Bereich der Wanddickenreduzierung eingehalten werden, um eine gleichmäßige Wassergeschwindigkeit im gesamten Wasserspalt zu garantieren. Insofern sieht die Ausführungsform gemäß den Merkmalen des Patentanspruchs 6 vor, daß der Wasserleitmantel einen rechteckigen Querschnitt aufweist und zwischen den Wasserleitmantel sowie die Stege bzw. die Flansche an den durch die Außenkontur des Kokillenrohrs sowie die Innenkontur des Wasserleitmantels gebildeten Querschnittsbereich angepaßte Füllstücke eingegliedert sind.Since the removal of heat by means of cooling water - as known - is determined by the water velocity in the water gap between the mold tube and the water jacket, this water gap should also be maintained in the wall thickness reduction to guarantee a uniform water velocity throughout the water gap. In this respect, the embodiment according to the features of claim 6 provides that the Wasserleitmantel has a rectangular cross-section and between the Wasserleitmantel and the webs or flanges are incorporated into the formed by the outer contour of the Kokillenrohrs and the inner contour of the Wasserleitmantels cross-sectional area matched patches.

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

Mit 1 ist in den Figuren 1 bis 4 ein Kokillenrohr mit einem Doppel-T-förmigen Innenund Außenquerschnitt im Beam-Blank-Format bezeichnet. Das Kokillenrohr 1 dient zum Stranggießen von Metallen. In den Figuren 3 und 4 ist die Krümmung des Kokillenrohrs 1 in Längsrichtung nicht dargestellt.1, a mold tube with a double-T-shaped inner and outer cross-section in the beam blank format is denoted by 1 in FIGS. The mold tube 1 is used for continuous casting of metals. In Figures 3 and 4, the curvature of the mold tube 1 is not shown in the longitudinal direction.

Wie Figur 3 näher erkennen läßt, ist die Wanddicke D des Kokillenrohrs 1 in den gerundeten Übergangsbereichen 2 von den einander frontal gegenüber liegenden, zur Längsachse 3 hin eingezogenen mittleren Stegen 4 auf die angrenzenden schräg gestellten Flansche 5 geringer als die Wanddicke D1 in den restlichen Wandabschnitten 6 und 7 bemessen.As can be seen in more detail in FIG. 3, the wall thickness D of the mold tube 1 in the rounded transitional areas 2 is smaller than the wall thickness D1 in the remaining wall sections, from the central webs 4, which are located opposite one another and are inclined towards the longitudinal axis 3, on the adjacent inclined flanges 5 6 and 7.

Die Wanddickenreduzierung erfolgt bei der Ausführungsform der Figuren 1 bis 3 dadurch, daß außenseitig der Übergangsbereiche 2 längs gerichtete muldenförmige Aussparungen 8 vorgesehen sind. Diese Aussparungen 8 erstrecken sich, wie die Figur 2 erkennen läßt, lediglich im Höhenbereich des nicht näher veranschaulichten Badspiegels. Die Krümmung 9 der Aussparungen 8 ist weitgehend an die Krümmung 10 der inneren Oberfläche 11 des Kokillenrohrs 1 in den Übergangsbereichen 2 angepaßt.The wall thickness reduction takes place in the embodiment of Figures 1 to 3, characterized in that the outside of the transition regions 2 longitudinally directed trough-shaped recesses 8 are provided. These recesses 8 extend, as the figure 2 reveals, only in the height range of the not further illustrated bath mirror. The curvature 9 of the recesses 8 is largely adapted to the curvature 10 of the inner surface 11 of the mold tube 1 in the transition regions 2.

Umfangsseitig des Kokillenrohrs 1 befindet sich ein nur aus der Figur 3 erkennbarer Wasserleitmantel 12 mit einem im wesentlichen rechteckigen Querschnitt. Zwischen dem Wasserleitmantel 12 und der äußeren Oberfläche 13 des Kokillenrohrs 1 wird ein Wasserspalt 14 gebildet, durch den Kühlwasser von unten nach oben mit einer vorbestimmten Wassergeschwindigkeit geführt wird.On the circumference of the mold tube 1 is a recognizable only from the figure 3 Wasserleitmantel 12 with a substantially rectangular cross-section. Between the Wasserleitmantel 12 and the outer surface 13 of the mold tube 1, a water gap 14 is formed, is guided by the cooling water from bottom to top with a predetermined water velocity.

Damit auch in den seitlichen Kanälen 15 des Kokillenrohrs 1, welche gemäß den Figuren 1 und 2 am oberen Ende durch Abschlußdeckel 16 verschlossen sind, eine gleichmäßige Wassergeschwindigkeit im Wasserspalt 14 erreicht wird, werden diese Kanäle 15 mit Füllstücken 17 versehen, die im oberen Bereich auch an die muldenförmigen Aussparungen 8 angepaßt sind.Thus even in the lateral channels 15 of the mold tube 1, which are closed according to Figures 1 and 2 at the upper end by end cover 16, a uniform water velocity in the water gap 14 is achieved, these channels 15 are provided with patches 17, which in the upper area also are adapted to the trough-shaped recesses 8.

In der Figur 4 sind vier verschiedene Ausführungsformen dargestellt, wie die Wanddickenreduzierung des Kokillenrohrs 1 auch noch realisiert werden kann.Four different embodiments are shown in FIG. 4, as the wall thickness reduction of the mold tube 1 can also be realized.

In den Übergangsbereichen 2a, 2b, 2c sind außenseitig mehrere längs gerichtete, nebeneinander verlaufende Nuten 18, 18a, 18b vorgesehen. Während in dem Übergangsbereich 2a die Nuten 18 einen dreieckförmigen Querschnitt haben, besitzen die Nuten 18a, 18b in den Übergangsbereichen 2b, 2c gerundete Böden. Dabei haben die Nuten 18b im Übergangsbereich 2c eine größere Tiefe als die Nuten 18a im Übergangsbereich 2b.In the transitional areas 2a, 2b, 2c, a plurality of longitudinally directed, adjacent grooves 18, 18a, 18b are provided on the outside. While in the transition region 2a, the grooves 18 have a triangular cross-section, the grooves 18a, 18b in the transition regions 2b, 2c have rounded bottoms. In this case, the grooves 18b have a greater depth in the transition region 2c than the grooves 18a in the transition region 2b.

Im Übergangsbereich 2d ist die Wanddickenreduzierung durch Bohrungen 19 realisiert. Diese Bohrungen 19 liegen näher zur äußeren Oberfläche 13 des Kokillenrohrs 1 als zur inneren Oberfläche 11.In the transition region 2d, the wall thickness reduction is realized by holes 19. These holes 19 are closer to the outer surface 13 of the mold tube 1 as the inner surface eleventh

Sowohl die Nuten 18, 18a, 18b als auch die Bohrungen 19 erstrecken sich, wie die Aussparungen 8, nur im Höhenbereich des Badspiegels.Both the grooves 18, 18a, 18b and the holes 19 extend, as the recesses 8, only in the height range of the bath level.
