Abstract
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 pouring device is provided, the opening through a vertically movable diving bell is closable.
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.Pouring devices of this type are used, for example, in foundries to dispense liquid Metal (such as iron, steel, aluminum, gray cast iron, nodular cast iron, graphite cast iron, etc.) e.g. in Pouring watering boxes. As a rule, there is a spout made of refractory material in the floor embedded, which is flush with the bottom of the pouring device. The spout will closed by a rod-shaped plug, the generally rounded end of which Closes the opening of the spout and can be raised for the pouring process, whereby the opening is released. The problem arises here that when the Casting process is not finished in time, the floating on the liquid metal Slag emerges from the pouring device at the end of the pouring process and the respective one Batches contaminated. On the other hand, if the casting process is stopped too soon, remains Metal unused in the casting device, which is also a disadvantage.
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 therefore to ensure that virtually everything in the Pouring device located metal can be shed without the risk of a Pouring slag.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Ausguß um seine dem Innenbereich der Vergießeinrichtung zugewandte Öffnung eine Erhebung aufweist, so daß die Öffnung oberhalb des Bodens der Vergießeinrichtung angeordnet ist und daß die Tauchglocke an ihrer Unterseite eine der Erhebung entsprechende Aussparung aufweist, so daß der Ausguß durch die Tauchglocke formschlüssig verschließbar ist.This object is achieved in that the spout to its Interior of the potting device facing an elevation, so that the Opening is arranged above the bottom of the potting device and that the diving bell has on its underside a recess corresponding to the elevation, so that the spout is positively closable by the diving bell.
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, when the diving bell is raised, So with the spout open, insert the metal from below into the recess in the diving bell and leaves the pouring device through the opening. The diving bell holds back the slag, until there is no more metal in the casting device and the slag at the bottom of the Pouring device has arrived. The opening arranged around the opening of the spout 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 elevation or the recess in is essentially semicircular.
Eine andere Ausbildung besteht darin, daß die Erhebung bzw. die Aussparung im wesentlichen konisch ausgebildet ist.Another training is that the collection or recess in is essentially conical.
Im Rahmen der Erfindung liegt auch, daß der Durchmesser der Tauchglocke in ihrem unteren Bereich zu dem unteren Ende hin zunimmt.It is also within the scope of the invention that the diameter of the diving bell is in its lower Area increases towards the lower end.
Schließlich besteht eine Weiterbildung der Erfindung darin, daß die Tauchglocke radiale Vorsprünge zum Abhalten von Schlacke aufweist.Finally, a development of the invention is that the diving bell is radial Has protrusions for holding slag.
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 What is possible because of the lower amount of inclusions that can be achieved in this way cast metal means an increase in quality. They are also longer in this way Pouring times possible because the metal contained in the casting device is practically complete can be emptied.
Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung erläutert.An exemplary embodiment of the invention is explained below with reference to a drawing.
Es zeigt
- Fig. 1
- eine geschnittene Darstellung einer erfindungsgemäßen Vergießeinrichtung.
- Fig. 1
- a sectional view of a potting device according to the 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 halbkreisförmig 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 potting device according to the invention consists of a
Container, in the bottom 1 of which a
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 bottom of the diving bell 5 which closes the
Wie dargestellt, kann der untere Bereich 8 der Tauchglocke 5 einen zum freien Ende der Tauchglocke 5 hin zunehmenden Durchmesser aufweisen. Weiterhin können Vorsprünge 9 vorgesehen sein, um am Ende des Gießvorganges das Eintreten der Schlacke in die Öffnung 3 zu verhindern.As shown, the lower region 8 of the diving bell 5 can one to the free end of the Diving bell 5 have increasing diameter. Projections 9 be provided in order to prevent the slag from entering the opening 3 at the end of the casting process to prevent.
