Abstract

Die Erfindung betrifft einen feuerfesten Ausguss zur Anordnung in der Wandung von metallurgischen Gefäßen, inbesondere für Stahlschmelzen, mit einer ein oberes und ein unteres Ende aufweisenden Durchlauföffnung, einer die Durchlauföffnung seitlich umschließenden Innenwand (2) aus einem Festelektrolytmaterial, mit wenigstens einer an der der Durchlauföffnung abgewandten Außenseite des Festelektrolytmaterials elektrisch leitend angeordneten Elektrode (3,4), an welcher Anschlussleitungen (5) angeordnet sind und mit einem die Außenseite des Festelektrolytmaterials und die Elektrode mindestens teilweise umschließenden thermischen Isoliermaterial. Um die bekannten Lösungen zu verbessern und eine hohe Funktionssicherheit zu schaffen, ist der Ausguss dadurch gekennzeichnet, dass die mindestens eine Elektrode im wesentlichen aus einem Metall, das einen Schmelzpunkt von mindestens 1400°C aufweist und/oder aus mindestens einem seiner Oxide gebildet ist.
