Description
Die Erfindung betrifft eine weitere Ausgestaltung der den Gegenstand des Patentes 702 638 bildenden Vorrichtung. Jene Vorrichtung zum ununterbrochenen Gießen von Metallrohren hat als wesentliches Merkmal eine Zuflußleitung für das flüssige Metall, an die sich unmittelbar der Dorn anschließt und die seitlichen öffnungen für den Übertritt des Metalls in den Ringraum zwischen Dorn und Kokille hat.The invention relates to a further embodiment of the subject matter of the patent 702 638 forming device. That device for the continuous casting of metal pipes has as an essential feature an inflow line for the liquid metal, to which the mandrel directly adjoins and the side openings for the passage of the metal into the annular space between the mandrel and Has mold.
Nun hat sich aber gezeigt, daß bei hoher Gießgeschwindigkeit der unmittelbare Übertritt des Metallstromes in den von dem Dorn und der Kokille gebildeten Ringraum insofern von Nachteil ist, als mit der durch das Aufschlagen des flüssigen Metalls an die Kokillenwandung sich ergebenden Durchwirbelung des Metalls eine Störung der Abkühlungsbedingungen verbunden ist.It has now been shown, however, that at high casting speeds, the immediate transfer occurs of the metal flow in the annular space formed by the mandrel and the mold is disadvantageous than with the impact of the liquid metal on the The swirling of the metal resulting from the mold wall disturbs the cooling conditions connected is.
Die Beruhigung des Metallstromes und gegebenenfalls auch eine gleichzeitige Entgasung des Metalls wird nun durch eine besondere Ausbildung des Kopfes des sich an das untere Ende des Zuflußrohres anschließenden und sich nach unten verjüngenden Domes erreicht. The calming of the metal flow and possibly also a simultaneous degassing the metal is now through a special design of the head of the adjoining the lower end of the feed pipe and the domes tapering downwards.
Erfindungsgemäß ist im Kopf des Domes eine durch einen Kegel gebildete ringmulden-According to the invention, an annular trough formed by a cone is in the head of the dome
förmige Vertiefung vorgesehen, die der Aufnahme und Verteilung des aus dem Zuleitungsrohr zufließenden Metalls dient. Shaped recess is provided, which is used to receive and distribute the metal flowing in from the supply pipe.
Oberhalb des die Ringmulde bildenden Kegels befindet sich das Ende des Zuleitungsrohres, aus der das flüssige Metall in die Ringmulde fließt, von wo es durch seitlich angeordnete Above the cone that forms the trough is the end of the feed pipe from which the liquid metal enters the trough flows from where it is arranged through laterally
Austrittsöffnungen in den durchOutlet openings in the through
den Dorn und die Kokille gebildeten Ringraum übertritt. Diese seitlichen Austrittsöffnungen können nun entweder radial auf die Kokillenwand oder so stark abwärts gerichtet sein, daß die Durchwirbelung des zufließenden Metalls vermieden wird. Oberhalb des Ringraums können ebenfalls ringförmige Schlitze oder öffnungen angeordnet sein, durch die aus dem zufließenden Metall austretende Gase abgeführt werden können. In weiterer Ausbildung der Erfindung wird der Dorn in Richtung des Zuleitungsrohrs heb- und senkbar ausgestattet, wodurch der Zulauf des flüssigen Metalls in die Gießvorrichtung auf eine solche Weise geregelt wird, daß die Mündung des Zuleitungsrohres durch den die Ringmulde bildenden Kegel mehr oder weniger verschlossen werden kann.the mandrel and the mold crosses the annular space formed. These side outlet openings can now either radially the mold wall or so strongly downwards that the turbulence of the inflowing Metal is avoided. Annular slots or openings can also be arranged above the annular space, through which gases escaping from the incoming metal can be discharged. In further development of the invention, the mandrel is lifted in the direction of the feed pipe and lowerable, whereby the inflow of the liquid metal into the casting device is regulated in such a way that the mouth of the supply pipe through the Annular trough forming cone can be more or less closed.
In der Zeichnung zeigt Abb. 1 den schematischen Längsschnitt durch ein erstes Ausführungsbeispiel und Abb. 2 einen Längsschnitt durch ein zweites Ausführungsbeispiel der Erfindung.In the drawing, Fig. 1 shows the schematic longitudinal section through a first embodiment and Fig. 2 is a longitudinal section through a second embodiment of the invention.
Das Ausführungsbeispiel der Abb. 1 zeigt eine Kokille i, die in der beim Stranggießen üblichen Weise von außen mit einem Kühlmittel, z. B. Wasser, bespült wird. In der Kokille i befindet sich der Dorn d, in den das Zuleitungsrohr α mündet. Unterhalb der Austrittsöffnungen b des Zuleitungsrohrs ist der die ringmuldenförmige Vertiefung 2 des Domes d bildende Kegel 1 angeordnet. Der Übertritt und die Verteilung des beruhigten Metalles aus der Vertiefung 2 erfolgt durch Öffnungen 3, die radial auf die Kokillenwandung gerichtet sind und zur Vermeidung der Bildung von gegen die Kokillenwandungen gerichteten Brandungswellen etwas schräg nach unten führen. Die aus dem zufließenden Metall austretenden Gase können aus dem Ringschlitz 5 entweichen. Durch Heben und Senken des an dem Gestänge 9 und 10 aufgehängten Domes kann die Gießgeschwindigkeit geregelt oder das Rohr α ganz abgesperrt werden.The embodiment of Fig. 1 shows a mold i, which in the usual manner in continuous casting from the outside with a coolant, for. B. water is rinsed. In the mold i is the mandrel d, into which the feed pipe α opens. The cone 1 forming the annular trough-shaped recess 2 of the dome d is arranged below the outlet openings b of the supply pipe. The transfer and distribution of the calmed metal from the recess 2 takes place through openings 3, which are directed radially towards the mold wall and lead somewhat obliquely downward to avoid the formation of surf waves directed against the mold walls. The gases emerging from the incoming metal can escape from the annular slot 5. By raising and lowering the dome suspended from the rods 9 and 10, the casting speed can be regulated or the pipe α can be shut off completely.
Bei der in Abb. 2 gezeigten abgeänderten Ausführungsform schließen sich an die muldenförmige Vertiefung 2 im Dorn d noch Öffnungen 6 an, die das Entgasen des aus der Mulde 2 strömenden Metalls erleichtern. Die Ausströmöffnungen 3' sind bei diesem Beispiel, das insbesondere großer Gießgeschwindigkeit dienen soll, ziemlich stark nach unten geneigt, damit die genannten Brandungswellen an der Kokillenwandung nicht entstehen können.In the modified embodiment shown in FIG. 2, the trough-shaped depression 2 in the mandrel d is followed by openings 6 which facilitate the degassing of the metal flowing out of the trough 2. The outflow openings 3 'in this example, which is intended in particular to serve a high casting speed, are inclined quite sharply downward, so that the surfacing waves mentioned cannot arise on the mold wall.
