Description

Die Erfindung bezieht sich auf einen Warmhalteofen entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a holding oven according to the preamble of claim 1.

Bei einem bekannten Warmhalteofen der vorgenannten Art kann nach dem Entleeren des Ofens bis unterhalb des unteren Randes der waagerechten Gießöffnung die Kokille rasch gegen eine andere Kokille ausgewechselt werden, ohne daß der Warmhalteofen deshalb abzukühlen braucht (DE-A-2 707 533).In a known holding furnace of the aforementioned type, after the furnace has been emptied to below the lower edge of the horizontal pouring opening, the mold can be quickly replaced with another mold without the holding furnace needing to cool down (DE-A-2 707 533).

Ein anderer bekannter Warmhalteofen ist um eine waagerechte Achse kippbar. Zum Wechseln der Stranggießkokille wird der Warmhalteofen so weit hochgekippt, bis der Schmelzspiegel unterhalb der Gießöffnung liegt. Nach dem Auswechseln dieser Kokille wird der Warmhalteofen wieder in seine Betriebslage zurückgeschwenkt (DE-B-2 743 806).Another known holding oven can be tilted about a horizontal axis. To change the continuous casting mold, the holding furnace is tilted up until the melting level is below the pouring opening. After replacing this mold, the holding furnace is pivoted back into its operating position (DE-B-2 743 806).

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Ausstoß des Warmhalteofens wesentlich zu vergrößern. Diese Aufgabe wird durch die Merkmale im Kennzeichnungszeichnungsteil des Anspruchs 1 erfindungsgemäß gelöst. An der zusätzlichen Gießöffnung muß die Kokille ebenfalls mittels eines Zwischenflanschs angeordnet sein, um ohne Abkühlen des Warmhalteofens im wesentlichen auf Umgebungstemperatur eine der Gießöffnungen stillegen oder diese Kokille nach entsprechender Leerung des Warmhalteofens gegen eine andere Kokille auswechseln zu können. Wenn alle Kokillen wegen Änderung oder Unbrauchbarkeit ausgewechselt werden müssen, wird der Warmhalteofen bis zum untersten Rand der untersten Gießöffnung entleert. Nach dem Auswechseln der Kokille oder der Kokillen kann der Warmhalteofen wieder angefahren werden und ist wieder ständig betriebsbereit.The present invention has for its object to significantly increase the output of the holding furnace. This object is achieved according to the invention by the features in the characterizing part of claim 1. At the additional pouring opening, the mold must also be arranged by means of an intermediate flange in order to shut down one of the pouring openings without cooling the holding furnace substantially to ambient temperature or to be able to replace this mold with another mold after the holding furnace has been emptied accordingly. If all molds have to be replaced due to changes or uselessness, the holding furnace is emptied to the bottom of the bottom pouring opening. After changing the mold or the molds, the holding furnace can be restarted and is always ready for use again.

Die Ansprüche 2 und 3 betreffen bevorzugte Weiterbildungen des Gegenstandes der Erfindung.Claims 2 and 3 relate to preferred developments of the subject matter of the invention.

Weitere Vorteile ergeben sich aus der Beschreibung und der Zeichnung. In dieser ist ein Warmhalteofen als Ausführungsbeispiel des Gegenstandes der Erfindung schematisch dargestellt. Es zeigen

  • Fig. 1 und 2 jeweils einen lotrechten Schnitt in zwei senkrecht zueinander stehenden Ebenen,
  • Fig. 3 einen Ausschnitt aus Fig. 1 oder 2 mit zusätzlichen Teilen.
Further advantages result from the description and the drawing. In this a holding oven is shown schematically as an embodiment of the subject of the invention. Show it
  • 1 and 2 each have a vertical section in two mutually perpendicular planes,
  • Fig. 3 shows a detail from Fig. 1 or 2 with additional parts.

Ein Ofenmantel 1 ist aus Grobblechplatten zusammengeschweißt und mit feuerfesten Steinen 2 und einer Schicht 3 aus einer feuerfesten Masse ausgekleidet. Der Warmhalteofen ist im Querschnitt etwa quadratisch ausgebildet und hat auf drei Seiten je eine Gießöffnung 22 bzw. 23 bzw. 24. Jede der Gießöffnungen 22 bis 24 durchsetzt eine auf dem Ofenmantel 1 befestigte gußeiserne Frontplatte 4. An jeder der Frontplatten ist ein Zwischenflansch 5 (Fig. 3) mit Kokille 6 und Kühler 7 befestigt. An der Unterseite des Warmhalteofens ist ein am Ofenmantel 1 fest angeschweißter Flansch 8 zur Anbringung eines Induktors 9 vorgesehen. Auf der Oberseite des Warmhalteofens ist ein abnehmbarer Deckel 10 angeordnet, der mit einer feuerfesten Masse ausgegossen ist und einen Brennerstein 12 zur Aufnahme eines nicht dargestellten Brenners aufweist. Im unteren Bereich des Warmhalteofens ist eine Temperaturmeßstelle 13 vorgesehen, die ein Thermoetement.14 hat. Die Lage des Zwischenflanschs 5 ist auf der Frontplatte 4 mittels Paßstiften genau festgelegt. Der Bereich zwischen der Kokille 6 und der die Steine 2 bedeckenden Schicht 3 wird durch einen von einem Isolierkörper 16 umgebenen Zuführtrichter 17 überbrückt. Der Isolierkörper 16 besteht aus einer Isoliermasse und der Zuführtrichter 17 aus einer feuerfesten Masse. An der Stoßstelle zwischen der Mündung der Gießöffnung 22 oder 23 oder 24 und dem Zuführtrichter 17 sind die lichten Ausnehmungen jeweils gleich. Die Gießöffnungen 22 bis 24 sind im wesentlichen oval ausgebildet und verlaufen mit waagerechten Achsen und im wesentlichen mit waagerechten Wänden, wobei auch eine nach außen sich erweiternde Keilform vorgesehen sein kann.A furnace jacket 1 is welded together from heavy plate and lined with refractory bricks 2 and a layer 3 of a refractory mass. The holding furnace is approximately square in cross-section and has a pouring opening 22 or 23 or 24 on each of three sides. Each of the pouring openings 22 to 24 passes through a cast iron front plate 4 fastened to the furnace casing 1. An intermediate flange 5 ( Fig. 3) with mold 6 and cooler 7 attached. On the underside of the holding furnace, a flange 8 is welded to the furnace jacket 1 to attach an inductor 9. On the top of the holding furnace, a removable cover 10 is arranged, which is filled with a refractory mass and has a burner block 12 for receiving a burner, not shown. In the lower area of the holding oven, a temperature measuring point 13 is provided, which has a thermocouple 14. The position of the intermediate flange 5 is precisely determined on the front plate 4 by means of dowel pins. The area between the mold 6 and the layer 3 covering the stones 2 is bridged by a feed hopper 17 surrounded by an insulating body 16. The insulating body 16 consists of an insulating compound and the feed funnel 17 consists of a refractory compound. At the joint between the mouth of the pouring opening 22 or 23 or 24 and the feed hopper 17, the clear recesses are the same. The pouring openings 22 to 24 are essentially oval in shape and run with horizontal axes and essentially with horizontal walls, it also being possible to provide a wedge shape which widens outwards.

Zwischen der Frontplatte 4 und dem Zwischenflansch 5 ist eine Dichtung 19 in Form einer Asbestplatte oder dergleichen vorgesehen. Der die Kokille 6 umgebende Kühler 7 ist mit seinem Flansch an einem Haltering 20 mittels Schrauben lösbar befestigt, der seinerseits an dem Zwischenflansch 5 ebenfalls mittels Schrauben lösbar befestigt ist. Zum Ausrichten der Kokille können am Befestigungsflansch des Kühlers 7 Langlöcher vorgesehen sein. Es ist möglich, an dem Zwischenflansch 5 mehrere Kokillen 6 anzuordnen.A seal 19 in the form of an asbestos plate or the like is provided between the front plate 4 and the intermediate flange 5. The cooler 7 surrounding the mold 6 is releasably attached with its flange to a retaining ring 20 by means of screws, which in turn is also releasably attached to the intermediate flange 5 by means of screws. To align the mold 7 slots can be provided on the mounting flange of the cooler. It is possible to arrange several molds 6 on the intermediate flange 5.

Jede der Gießöffnungen 22 bis 24 ist mit einer Frontplatte 4 und daran angebrachtem, jeweils mindestens eine Kokille tragendem Zwischenflansch 5 versehen. Die Gießöffnungen 22 bis 24 sind jeweils gleich ausgebildet und in gleicher Höhe angeordnet. Sie können auch unterschiedlich ausgebildet und in unterschiedlichen Höhen angeordnet sein.Each of the pouring openings 22 to 24 is provided with a front plate 4 and an intermediate flange 5 attached to it, each carrying at least one mold. The pouring openings 22 to 24 are each of the same design and arranged at the same height. They can also be designed differently and arranged at different heights.
