Description

Feuerfeste Einheit für einen Schiebeverschluss am Ausguss eines  Refractory unit for a sliding closure on the spout of a
Behälters für Metallschmelze  Container for molten metal
Die Erfindung betrifft eine feuerfeste Einheit für einen Schiebeverschluss am Ausguss eines Metallschmelze enthaltenden Behälters, mit einem am Behälterausguss einsetzbaren feuerfesten Adapterstein, einer daran anschliessenden feuerfesten Bodenplatte, an welche eine verschiebbare feuerfeste Schieberplatte anschliessbar ist, welche ein Öffnen bzw. Schliessen des Schiebeverschlusses ermöglicht, wobei neben der an den Adapterstein anschliessenden ersten Bodenplatte eine zweite Bodenplatte angrenzt, welche für einen Wechsel der ersten Bodenplatte unterhalb den Adapterstein einschiebbar ist. 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 B l 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. The invention relates to a refractory unit for a sliding closure at the spout of a molten metal containing container, with a usable at the container nozzle refractory adapter stone, an adjoining refractory bottom plate to which a sliding refractory slide plate is connected, which allows opening or closing of the sliding closure, wherein adjacent to the adapter plate adjoining the first bottom plate, a second bottom plate adjacent, which is inserted for a change of the first bottom plate below the adapter stone. 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 disclosed, for example, in EP 0 819 488 B1. 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 sealingly pressed with its upper sliding surface to a lower sliding surface of the bottom plate. 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, the housing frame must be detached from the base plate in each case.
