Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur kontinuierlichen Behandlung einer Metallschmelze nach dem Oberbegriff des Hauptanspruchs.The The invention relates to a device for continuous treatment a molten metal according to the preamble of the main claim.
Eine
solche Vorrichtung ist beispielsweise in der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur kontinuierlichen Behandlung einer Metallschmelze zu schaffen, bei dem die Reinigung leicht und über die gesamte Oberfläche der behandelten Schmelze möglich ist, ohne dass der Behandlungsprozess unterbrochen werden muss.Of the Invention is therefore based on the object, a device for to provide continuous treatment of a molten metal at the cleaning is easy and over the entire surface the treated melt possible is, without the treatment process must be interrupted.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs in Verbindung mit den Merkmalen des Oberbegriffs gelöst.These The object is achieved by the characterizing features of the main claim in connection with the Characteristics of the preamble solved.
Dadurch, dass der Einlass zur Zuführung der Schmelze in die Behandlungskammer und der Auslass zum Abführen der behandelten Schmelze aus der Behandlungskammer versetzt zueinander an gegenüberliegenden Seitenwänden angeordnet sind, und dass an mindestens einer Wand zwischen den Seitenwänden eine Reinigungstür zum Entfernen von Verunreinigungen vorgesehen ist, ist die Reinigung der Behandlungskammer möglich, ohne den Behandlungsprozess zu unterbrechen und ohne dass die Behandlungseinheiten aus der Schmelze gehoben werden müssen. weiterhin ist der Innenraum der Behandlungskammer, insbesondere die gesamte Oberfläche der be handelten Schmelze einfach zugänglich. Die mindestens eine Reinigungstür kann dabei relativ klein ausgeführt sein, so dass ein dichtes Abschließen sichergestellt ist und Lufteintritt in die Behandlungskammer sicher verhindert wird.Thereby, that the inlet to the feeder the melt into the treatment chamber and the outlet for discharging the Treated melt from the treatment chamber offset from each other at opposite sidewalls are arranged, and that at least one wall between the side walls a cleaning door is intended for removing impurities, is cleaning the treatment chamber possible, without interrupting the treatment process and without the treatment units must be lifted from the melt. continues the interior the treatment chamber, in particular the entire surface of the be treated melt easily accessible. The at least one cleaning door can run relatively small so that a tight seal is ensured and Air is safely prevented in the treatment chamber.
Durch die in den Unteransprüchen angegebenen Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen möglich.By in the subclaims specified measures Advantageous developments and improvements are possible.
Besonders vorteilhaft ist, dass im Bereich der Reinigungstür eine Rampe in die Schmelze hineinführt, wodurch Verunreinigungen auf der Oberfläche der Schmelze oder am Boden der Behandlungskammer mit einem geeigneten Werkzeug über die Rampe oder Reinigungsschräge (letztere soll durch den Begriff Rampe umfaßt sein) aus der Reinigungstür gezogen werden können.Especially It is advantageous that in the area of the cleaning door a ramp into the melt ushers, causing impurities on the surface of the melt or on the ground the treatment chamber with a suitable tool over the Ramp or cleaning slope (The latter should be covered by the term ramp) pulled out of the cleaning door can be.
Vorteilhaft ist, dass bei einer Ausführung des Behälters vorzugsweise eines Ofens mit lang gestreckten Seitenwänden an beiden kleineren Stirnflächen jeweils eine Reinigungstür mit Rampe vorgesehen ist, da auch in diesem Fall die gesamte Oberfläche der Schmelze zugänglich ist, ohne dass die an den Längsseiten vorgesehenen Schmelzezuführungen stören könnten.Advantageous is that in one execution of the container preferably a furnace with elongated side walls two smaller faces one cleaning door each provided with ramp, since in this case the entire surface of the Melt accessible is without those on the long sides provided melt feeds to disturb could.
In einem besonders vorteilhaften Ausführungsbeispiel ist der Einlass und/oder der Auslass für die Schmelze mit einem Siphon oder einem Wehr versehen, so dass keine Umgebungsluft durch den Ein- und Auslass in die Behandlungskammer gelangen kann, da die Schmelze unter dem Siphon oder dem Wehr der Behandlungskammer zu- oder aus der Behandlungskammer abströmt. Durch Vorsehen einer Inertgaszuführung kann in der Behandlungskammer nach dem Reinigungsvorgang schnell eine Inertgasatmosphäre erreicht werden.In In a particularly advantageous embodiment, the inlet and / or the outlet for the Melt provided with a siphon or a weir, so no Ambient air through the inlet and outlet into the treatment chamber can reach, as the melt under the siphon or the weir of the Treatment chamber on or flows out of the treatment chamber. By Providing an inert gas supply can be fast in the treatment chamber after the cleaning process an inert gas atmosphere be achieved.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Die einzige Figur zeigt eine schematische Darstellung der erfindungsgemäßen Vorrichtung in einem horizontalen Längsschnitt.One embodiment The invention is illustrated in the drawing and will be described in the following Description closer explained.
