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 External cross section in beam blank format according to the features in the preamble of 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.When casting metals continuously with a mold tube, the result Material temperatures in the mold wall from those that occur during continuous casting Heat loads and the cooling conditions caused by the respective cooling medium usually in the form of water in a water gap between one to the Outer contour of the mold tube adapted water jacket and the outer Surface of the mold tube flows from bottom to top, the resulting one Absorbs and removes heat. The heat is dissipated using cooling water 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. When continuously casting metals with a mold tube of the one in question Genus has been observed that due to the special geometry of the beam blank format extreme local heat loads in the transition areas from those that face each other head-on, drawn in towards the longitudinal axis middle ridges occur on the adjacent inclined flanges. This local heat loads lead to unfavorable geometric conditions Transition areas to overheating of the mold tube and consequently to one drastically reducing its service 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.Starting from the prior art, the invention is based on the object Mold tube with a double-T-shaped inside and outside cross section in beam blank format for continuous casting of metals, in which a local Overheating of the transition areas avoided and therefore a longer service life is achieved.

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

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.By at least partially reducing the wall thickness of the mold tube in the rounded transition areas will result in significantly improved heat dissipation achieved so that local overheating of the transition areas is avoided and consequently, the service life of the mold tube is significantly increased.

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 usually occurs in the mold tube at the level of the bath level, provide the features of claim 2 that the wall thickness in the Transitional areas are only reduced in the height area of the bathroom mirror.

Die Reduzierung der Wanddicke des Kokillenrohrs in den gerundeten Übergangsbereichen kann auf verschiedene Art und Weise erfolgen.The reduction in the wall thickness of the mold tube in the rounded transition areas can be done in different 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 are the outside Transition areas provided longitudinally trough-shaped recesses. The Curvature of the recesses can largely match the curvature of the be adapted to 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 enlarged so that a still 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 in the features of Claim 4 sees. Then the transition areas are on the outside several longitudinal, side by side grooves provided. The Cross-section and / or the depth of the grooves can be the same in each transition area or be sized differently. The cross section of the grooves can 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.Furthermore, it is conceivable according to the features of claim 5 that for Wall thickness reduction in the wall sections of the transition areas several longitudinal bores running side by side are provided. The size of the holes, their number, the distance to each other and also their position in relation the outside or inside contour of the mold tube can vary. It is advantageous however, if the holes are closer 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 dissipation of heat by means of cooling water - as is known - through the water speed in the water gap between the mold tube and the water jacket this water gap should also be determined in the area of wall thickness reduction be adhered to in order to maintain an even water speed in the guarantee entire water gap. In this respect, the embodiment according to the features of claim 6 before that the water jacket a has rectangular cross section and between the water jacket and the Web or the flanges on the through the outer contour of the mold tube and the Adapted inner contour of the water guiding jacket formed cross-sectional area Filler pieces are incorporated.

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 in Figures 1 to 4 is a mold tube with a double T-shaped inner and External cross-section in beam blank format. The mold tube 1 is used for the continuous casting of metals. In Figures 3 and 4, the curvature of the Chill tube 1 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 Figure 3, the wall thickness D of the mold tube 1 is in the rounded transition areas 2 from the frontally opposite one another, towards the longitudinal axis 3 drawn in middle webs 4 on the adjacent obliquely provided flanges 5 less than the wall thickness D1 in the rest Dimension wall sections 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 is reduced in the embodiment of FIGS. 1 to 3 in that outside of the transition areas 2 longitudinally trough-shaped Recesses 8 are provided. These recesses 8 extend like that Figure 2 reveals, only in the height range of the not illustrated Bath level. The curvature 9 of the recesses 8 largely matches the curvature 10 of the inner surface 11 of the mold tube 1 in the transition areas 2 customized.

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 circumferential side of the mold tube 1 there is one that can only be seen from FIG. 3 Wasserleitmantel 12 with a substantially rectangular cross section. Between the water jacket 12 and the outer surface 13 of the mold tube 1 a water gap 14 formed by the cooling water from the bottom up with a predetermined water speed is performed.

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.So that also in the side channels 15 of the mold tube 1, which according to the Figures 1 and 2 are closed at the upper end by end caps 16, one uniform water speed in the water gap 14 is reached, these will be Channels 15 provided with filler pieces 17, which in the upper area also to the trough-shaped recesses 8 are adapted.

In der Figur 4 sind vier verschiedene Ausführungsformen dargestellt, wie die Wanddickenreduzierung des Kokillenrohrs 1 auch noch realisiert werden kann.4 shows four different embodiments, such 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 transition areas 2a, 2b, 2c there are a plurality of longitudinal, adjacent grooves 18, 18a, 18b are provided. While in that Transition area 2a, the grooves 18 have a triangular cross section, the grooves 18a, 18b have rounded bottoms in the transition areas 2b, 2c. The grooves 18b in the transition area 2c have a greater depth than that Grooves 18a in the transition area 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 area 2d, the wall thickness is reduced by bores 19 realized. These holes 19 are closer to the outer surface 13 of the Mold tube 1 as to the inner surface 11.

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 bores 19 extend like that Cutouts 8, only in the height area of the bathroom mirror.
