Beschreibung
Zusammenfassung:	The invention relates to a device for closing a tap hole of a metallurgical vessel, in particular a converter, for the purpose of separating a molten metal and slag, having a slag stopper 1, which is situated outside the vessel, which provides an actuable closure element 8 that can be inserted into a tap hole, leaving an annular gap relative to the wall of the tap hole, and which provides a number of lines, in particular a pressurized-gas line 10 intended for the supply of the closure element, the slag stopper 1 comprising a connecting frame 2, which carries and fixes the parts of the slag stopper, this connecting frame, for its part, being secured releasably at a connecting point 11 on the metallurgical vessel 12. This allows a significant reduction in the time required for servicing or changing the slag stopper.
