Schiebeverschlüsse am Ausguss von Behältern für Metallschmelze sind in verschiedensten Ausgestaltungen bekannt. Ein Schiebeverschluss, der insbesondere zum Öffnen und Schliessen einer Konverter-Ausgussöffnung verwendet wird, ist beispielsweise in der EP 0 819 488 B1 offenbart. Er umfasst einen Gehäuserahmen, in welchem eine stationäre feuerfeste Verschlussplatte (eine sogenannte Bodenplatte) sowie eine dieser gegenüber verschiebbare, in einer Schiebereinheit gehaltene feuerfeste Schieberplatte angeordnet sind. Die Schieberplatte ist mit ihrer oberen Gleitfläche an eine untere Gleitfläche der Bodenplatte dichtend anpressbar. Der Gehäuserahmen ist an einer behälterfesten Grundplatte lösbar angebracht, wobei die Bodenplatte über ihre obere Gleitfläche mit einem in der Grundplatte eingesetzten feuerfesten Ausguss-Kopfteil verspannbar ist. Im Giessbetrieb sind die Feuerfestteile starkem Verschleiss ausgesetzt. Es ist daher erforderlich, sie relativ häufig auszutauschen. Dazu muss der Gehäuserahmen jeweils von der Grundplatte gelöst werden.Slide closures on the spout of containers for molten metal are known in various designs. A sliding closure, which is used in particular for opening and closing a converter spout opening, is for example in EP 0 819 488 B1 disclosed. It comprises a housing frame in which a stationary refractory closure plate (a so-called bottom plate) and one of these opposite sliding, held in a slide unit refractory slide plate are arranged. The slide plate is with its upper sliding surface on a lower sliding surface of the bottom plate sealingly pressed. The housing frame is detachably mounted on a container-fixed base plate, wherein the bottom plate is clamped on its upper sliding surface with a refractory spout head used in the base plate. In the casting operation, the refractory parts are exposed to heavy wear. It is therefore necessary to exchange them relatively frequently. For this purpose, the housing frame must be released in each case from the base plate.

Ein Schiebeverschluss gemäss der Druckschrift WO-A-2009/127333 ist mit einem an einem Ausguss des Behälters anbringbaren Gehäuserahmen versehen, in welchem eine feuerfeste Bodenplatte sowie eine Schiebereinheit mit einer an die Bodenplatte anpressbaren Schieberplatte und einer sich daran anschliessenden feuerfesten Ausgusshülse enthalten sind. Die Kassette ist mit einer neben der Bodenplatte angeordneten zweiten Bodenplatte versehen und kann im Gehäuserahmen quer zur Bewegungsrichtung der Schiebereinheit von einer Ausgangsstellung, in welcher die Bodenplatte sich in Betriebsstellung befindet, zu einer Endstellung, in welcher die zweite Bodenplatte die Betriebsstellung einnimmt, verschoben werden. Dadurch ist es möglich, die besonders bei Konvertern schnell verschleissende Bodenplatte rasch und bequem durch eine neue Bodenplatte zu ersetzen, ohne den Giessbetrieb zu unterbrechen.A sliding closure according to the document WO 2009/127333 is provided with an attachable to a spout of the container housing frame in which a refractory bottom plate and a slide unit are included with a pressure plate can be pressed against the bottom plate and an adjoining refractory spout. The cassette is provided with a second bottom plate arranged adjacent to the bottom plate and can be moved in the housing frame transversely to the direction of movement of the slide unit from a starting position in which the bottom plate is in the operating position to an end position in which the second bottom plate occupies the operating position. This makes it possible to replace quickly and conveniently by a new base plate, especially for converters quickly wearing floor plate without interrupting the casting operation.
