Abstract

Bei einem Verfahren zum Verschließen und Öffnen eines Stichloches eines metallurgischen Gefäßes, bei dem ein Verschlußkörper (4) unter Freilassung eines Ringspaltes zwischen dem Verschlußkörper (4) und der Wand des Stichloches aus einer Warteposition (I) in eine das Stichloch verdeckende Schließposition (II) und retour gebracht werden kann, und wobei, zumindest in der Schließposition (II), ein Druckgas in das Stichloch entgegen der Ausströmrichtung einer im metallurgischen Gefäß enthaltenen Schmelze eingeleitet wird, wird zur Vermeidung einer Verbärung der Verschlußkörper (4) mit in unterschiedlichen Flächen liegenden Bewegungsrichtungen aus der Warteposition (I) in die Schließposition (II) und retour bewegt.
