Abstract

Die Erfindung betrifft einen feuerfesten Ausguss (1) zur Anordnung in oder an einer Wandung eines metallurgischen Gefäßes (3), insbesondere für Stahlschmelzen, mit einer Durchflussöffnung (2) und einem die Durchflussöffnung umgebenden Durchflussrohr, wobei das Durchflussrohr eine die Durchflussöffnung begrenzende Oberfläche und ein äußeres Gehäuse aufweist. Um die aus dem Stand der Technik bekannten Lösungen zu verbessern, ist der Ausguss dadurch gekennzeichnet, dass das Durchflussrohr ein Oberteil (10) und ein Unterteil (6) aufweist, dass die die Durchflussöffnung (2) begrenzende Oberfläche des Oberteils (10) aus einem anderen Material gebildet ist als die die Durchflussöffnung (2) begrenzende Oberfläche des Unterteils (6) und dass das Unterteil (6) in oder an dem Oberteil (10) fixiert ist bzw. dadurch gekennzeichnet, dass das Durchflussrohr ein Oberteil (10) und ein Unterteil (6) aufweist, dass das Unterteil (6) an oder in dem Oberteil (10) fixiert ist und dass der Durchmesser der Durchflussöffnung (2) im Oberteil (10) größer ist als im Unterteil (6).

The invention relates to a refractory spout (1) for arrangement in or on a wall of a metallurgical vessel (3), in particular for molten steel, with a flow opening (2) and a flow pipe surrounding the flow opening, the flow pipe having a surface delimiting the flow opening and a has outer housing. In order to improve the solutions known from the prior art, the spout is characterized in that the flow tube has an upper part (10) and a lower part (6), that the surface of the upper part (10) delimiting the flow opening (2) consists of a different material is formed than the surface of the lower part (6) delimiting the flow opening (2) and that the lower part (6) is fixed in or on the upper part (10) or characterized in that the flow tube has an upper part (10) and a Lower part (6) has that the lower part (6) is fixed on or in the upper part (10) and that the diameter of the flow opening (2) in the upper part (10) is larger than in the lower part (6).
