TAP ON A METALLURGICAL VESSEL, IN PARTICULAR ON AN ELECTRIC ARC FURNACE

The invention relates to a tap on a metallurgical vessel, in particular on an electric arc furnace, comprising a fireproof end brick (6) having an outlet opening (10). On the lower end face (11) of the end brick (6), a groove (15) is provided, which is shaped in such a way that, during the draining...

Beschreibung
Zusammenfassung:	The invention relates to a tap on a metallurgical vessel, in particular on an electric arc furnace, comprising a fireproof end brick (6) having an outlet opening (10). On the lower end face (11) of the end brick (6), a groove (15) is provided, which is shaped in such a way that, during the draining of the vessel, a separation edge (16) is formed at the outlet opening (10) by means of the groove. Said groove (15) is annular and has an inclined surface (18) tilted radially outward. Thus, said separation edge (16) is formed directly adjacent to the outlet opening (10). Thus, the tap can be cleaned by shearing off by means of the front edge of the plate of the closing device without manual effort after each tapping process.
