Abstract

Die Erfindung betrifft eine Positioniereinrichtung für Brennstoff/Sauerstoff-Lanzen zum Eintrag von Einsatz- und Brennstoffen sowie Oxidationsmitteln, insbesondere von Sauerstoff oder sauerstoffhaltigen Gemischen, in eine Schmelzzone eines Schmelzofens zur Erzeugung von Metallen, insbesondere von Gußeisen und Metalllegierungen in einem Ofenschacht eines Kupolofens, mittels welcher die Injektionslanze in einem in die Schmelzzone einmündenden Einbringkanal axial verfahrbar angeordnet ist.
Erfindungsgemäß wird dadurch, dass die Positioniereinrichtung ein Führungsgehäuse (1) aufweist, in dessen Schlittenkammer (5) die mit einer Federaufhängung (3) verbundene Injektionslanze (2) mit einem Führungseinbau (4) axial verschiebbar angeordnet ist, ein optimaler Eintrag von Einsatz- und Brennstoffen sowie von Oxidationsmittel in das in der Schmelzzone angeordnete Koksbett gewährleistet und zudem eine Beschädigung oder Zerstörung der Injektionslanze durch thermische Einflüsse der Schmelzzone ausgeschlossen.
