Abstract

Zur metallurgischen Behandlung von Stahlschmelzen wird eine Lanze (7) durch ein Führungsrohr (8) mit Stopfbüchse (14) in ein Reaktionsgefäß geführt, auf welchem sich ein wassergekühlter Stutzen (1) mit Anschlussflansch (4) und einem vakuumdichten Gehäuse (5) mit Gehäuseflansch (3) befindet sowie einem zwischen Gehäuse und Stopfbüchsen-Führungsrohr (8) eingebauten Kompensator (12) zum Ausgleich von lateralen als auch axialen oder angularen Relativbewegungen zwischen Führungsrohr (8) und Gehäuse (5) während des Bewegungsablaufs. Dabei wird der untere Flansch des Kompensators (12) mit einem am Führungsrohr (8) mit Stopfbüchse (14) angebrachten Flansch (10) verbunden und der obere Flansch des Kompensators (12) mit dem oberen Gehäuseflansch (11) verschraubt, so daß der im Inneren zwischen den Kompensatorwänden und den Flanschen einerseits und der Außenfläche des Führungsrohres (8) andererseits gebildete ringförmige Raum (6) in Verbindung mit der Außenluft steht, wogegen der den Kompensator (12) umgebende Innenraum (5) der Gehäusekammer mit dem im Reaktionsgefäß herrschenden Vakuumdruck in Verbindung steht.
