Description
Die Erfindung betrifft eine Vergießeinrichtung für flüssiges Metall, in deren Boden ein Ausguß zum Entleeren der Vergießeinrichtung vorgesehen ist, dessen Öffnung durch eine in vertikaler Richtung bewegliche Tauchglocke verschließbar ist.The invention relates to a pouring device for liquid metal, in the bottom of a spout for emptying the Vergießeinrichtung is provided, the opening of which is closable by a dipping bell movable in the vertical direction.
Derartige Vergießeinrichtungen werden beispielsweise in Gießereien verwendet, um flüssiges Metall (wie Eisen, Stahl, Aluminium, Grauguß, Sphäroguß, Graphitguß, usw.) z.B. in Gießkästen zu gießen. In aller Regel ist im Boden ein Ausguß aus Feuerfestmaterial eingelassen, der bündig mit dem Boden der Vergießeinrichtung abschließt. Der Ausguß wird durch einen stabförmigen Stopfen verschlossen, dessen in der Regel abgerundetes Ende die Öffnung des Ausgusses verschließt und der für den Gießvorgang angehoben werden kann, wodurch die Öffnung freigegeben wird. Hierbei ergibt sich das Problem, daß, wenn der Gießvorgang nicht rechtzeitig beendet wird, die auf dem flüssigen Metall aufschwimmende Schlacke am Ende des Gießvorganges aus der Vergießeinrichtung austritt und die jeweiligen Chargen verunreinigt. Wird andererseits der Gießvorgang zu früh abgebrochen, verbleibt Metall ungenutzt in der Vergießeinrichtung, was ebenfalls von Nachteil ist.Such potting devices are used, for example, in foundries to treat liquid metal (such as iron, steel, aluminum, gray cast iron, nodular cast iron, graphite cast iron, etc.) e.g. to pour into casting boxes. As a rule, a spout made of refractory material is embedded in the bottom, which is flush with the bottom of the Vergießeinrichtung. The spout is closed by a rod-shaped plug, the generally rounded end of which closes the opening of the spout and which can be raised for the casting, whereby the opening is released. This results in the problem that, if the casting is not completed in time, the floating on the liquid metal slag exits the casting at the end of the casting and contaminated the respective batches. On the other hand, if the casting is stopped too early, metal remains unused in the Vergießeinrichtung, which is also disadvantageous.
Aufgabe der Erfindung ist es somit, sicherzustellen, daß praktisch das gesamte in der Vergießeinrichtung befindliche Metall vergossen werden kann, ohne daß die Gefahr eines Vergießens von Schlacke besteht.The object of the invention is thus to ensure that virtually all of the metal contained in the Vergießeinrichtung can be cast without the risk of potting slag exists.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of
Da die leichtere Schlacke auf dem Metall aufschwimmt, tritt bei angehobener Tauchglocke, also bei geöffnetem Ausguß das Metall von unten in die Aussparung der Tauchglocke ein und verläßt die Vergießeinrichtung durch die Öffnung. Die Tauchglocke hält die Schlacke zurück, bis kein Metall mehr in der Vergießeinrichtung enthalten ist und die Schlacke am Boden der Vergießeinrichtung angelangt ist. Die um die Öffnung des Ausgusses angeordnete Öffnung verhindert dann das Austreten der Schlacke.Since the lighter slag floats on the metal, occurs when raised diving bell, so with the spout open, the metal from below into the recess of the diving bell and leaves the Vergießeinrichtung through the opening. The immersion bell retains the slag until no more metal is contained in the casting device and the slag at the bottom of the Vergießeinrichtung has arrived. The opening disposed around the spout opening then prevents the slag from escaping.
Eine Ausbildung der Erfindung besteht darin, daß die Erhebung bzw. die Aussparung im wesentlichen halbkreisförmig ausgebildet ist.An embodiment of the invention is that the survey or the recess is formed substantially semicircular.
Eine andere Ausbildung besteht darin, daß die Erhebung bzw. die Aussparung im wesentlichen konisch ausgebildet ist.Another embodiment is that the survey or the recess is formed substantially conical.
Im Rahmen der Erfindung liegt auch, daß der Durchmesser der Tauchglocke in ihrem unteren Bereich zu dem unteren Ende hin zunimmt.In the context of the invention is also that the diameter of the dipping bell increases in its lower portion to the lower end.
Die Vorteile der Erfindung bestehen im wesentlichen darin, daß ein schlackenfreieres Gießen möglich wird, was aufgrund der dadurch erzielbaren geringeren Menge an Einschlüssen im gegossenen Metall eine Qualitätssteigerung bedeutet. Weiterhin sind auf diese Weise längere Gießzeiten möglich, da das in der Vergießeinrichtung enthaltene Metall praktisch vollständig entleert werden kann.The advantages of the invention consist essentially in that a slag-free casting is possible, which means an increase in quality due to the achievable thereby lower amount of inclusions in the cast metal. Furthermore, longer casting times are possible in this way, since the metal contained in the Vergießeinrichtung can be almost completely emptied.
Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung erläutert.In the following an embodiment of the invention will be explained with reference to a drawing.

- Fig. 1
- a sectional view of a Vergießeinrichtung invention.
Wie in Fig. 1 dargestellt, besteht die erfindungsgemäße Vergießeinrichtung aus einem Behälter, in dessen Boden 1 ein Ausguß 2 angeordnet ist. Dieser Ausguß 2 weist eine Öffnung 3 auf, durch die die Vergießeinrichtung entleert wird. Um die Öffnung 3 herum ist eine Erhebung 4 angeordnet, so daß die Öffnung 3 oberhalb des Bodens 1 der Vergießeinrichtung angeordnet ist. Die Erhebung 4 kann, statt wie hier halbkugelförmig zu sein, beliebige andere Formen aufweisen, z.B. konisch ausgebildet sein. Durch diese Erhebung 4 wird verhindert, daß am Ende des Gießvorganges die auf dem Metall aufschwimmende Schlacke aus der Vergießeinrichtung austritt.As shown in Fig. 1, the Vergießeinrichtung invention consists of a container, in the
Die die Öffnung verschließende Tauchglocke 5 weist an ihrer Unterseite 6, die der Öffnung 3 zugewandt ist, eine Aussparung 7 auf, deren Form der der Erhebung 4 entspricht, so daß die Tauchglocke 5, wenn sie auf der Erhebung 4 aufsitzt, die Öffnung 3 formschlüssig verschließt. Das Metall tritt also bei geöffneter Tauchglocke 5 in den Spalt zwischen Ausguß 2 und Tauchglocke 5 ein, läuft nach oben zu der Öffnung 3 und verläßt durch diese die Vergießeinrichtung. Die Schlacke wird hierbei durch die Form der Tauchglocke 5 und der Erhebung 4 am Austreten aus der Vergießeinrichtung gehindert, wobei die Höhe der Erhebung 4 und die Aussparung 7 der Tauchglocke 5 den jeweiligen Verhältnissen angepaßt werden können.The closing the
Wie dargestellt, kann der untere Bereich 8 der Tauchglocke 5 einen zum freien Ende der Tauchglocke 5 hin zunehmenden Durchmesser aufweisen. Weiterhin sind Vorsprünge 9 vorgesehen sein, um am Ende des Gießvorganges das Eintreten der Schlacke in die Öffnung 3 zu verhindern.As illustrated, the lower portion 8 of the
