Abstract

Die Erfindung betrifft einen feuerfester Ausguss für ein metallurgisches Gefäß, insbesondere für Stahlschmelzen, mit einer ein oberes und ein unteres Ende aufweisenden Durchlauföffnung (1) und einer die Durchlauföffnung seitlich umschließenden Innenwand. Um die bekannten Ausgüsse, insbesondere hinsichtlich ihrer Thermoschockbeständigkeit zu verbessern, ist in der Durchlauföffnung entlang der Innenwand entweder ein Heizer (2) oder ein thermisch isolierendes, sich bei Berührung mit flüssigem Stahl auflösendes oder verbrennendes Material oder eine Kombination daraus angeordnet.
