Abstract

Beim Abstechen einer Metallschmelze (11) durch eine seitlich im Boden (2) eines kippbaren runden oder ovalen metallurgischen Gefäßes (1), insbesondere eines Elektrolichtbogenofens, angeordnete Abstichöffnung (7), wird ein schlackenfreies Abstechen dadurch erzielt, daß im Bereich oberhalb der Abstichöffnung (7) durch mindestens eine innen an der Seitenwand des Gefäßes angeordnete Blasvorrichtung (Brenner 10) vorgesehen ist, durch die die Schlacke (12) aus diesem Bereich entfernt wird. When tapping a molten metal (11) through one laterally in the bottom (2) of a tiltable round or oval metallurgical vessel (1), especially an electric arc furnace, arranged tap opening (7), is a slag-free tapping achieved in that Area above the tap hole (7) at least one inside on the side wall of the Vessel arranged blowing device (burner 10) is provided, through which the slag (12) this area is removed.
