Abstract

Die Erfindung betrifft einen Spülstein für metallurgische Gefäße mit einer Spülkeramik (1), welche an einer Seite ein Bodenabschlussblech (2) mit einer Gaszuführungsvorrichtung aufweist, wobei die Gaszuführungsvorrichtung mit Hilfe einer Verschlussvorrichtung verschließbar ist und eine im Bodenabschlussblech (2) angeordnete Gaseintrittsöffnung (3) umfasst. Dieser Spülstein zeichnet sich dadurch aus, dass der Spülgaseintrittsöffnung (3) eine Federzunge (4) zugeordnet ist, deren erstes Ende (5) am Bodenabschlussblech (2) befestigt ist und deren zweites freies Ende (6) der Gaseintrittsöffnung (3) als Verschlussorgan zugeordnet ist, wobei das freie Ende (6) der Federzunge (4) durch strömendes Spülgas in eine Offenstellung bewegbar ist.

The invention relates to a flushing stone for metallurgical vessels with a flushing ceramic (1) which has a bottom end plate (2) with a gas supply device on one side, the gas supply device being closable with the aid of a closing device and a gas inlet opening (3) arranged in the bottom end plate (2). includes. This flushing stone is characterized in that a spring tongue (4) is assigned to the flushing gas inlet opening (3), the first end (5) of which is attached to the bottom end plate (2) and the second free end (6) is assigned to the gas inlet opening (3) as a closure member The free end (6) of the spring tongue (4) can be moved into an open position by flowing flushing gas.
