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.
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, characterized in that the slag stopper (1) comprises a connecting frame (2), which carries the parts of the slag stopper, this connecting frame (2), for its part, being secured releasably on the metallurgical vessel (12).
Method for mounting a slag stopper (1) on and for its removal from a metallurgical vessel, the slag stopper having a number of connections (4), which are assigned to significant lines of the slag stopper, characterized in that, as the slag stopper (2) is fixed on the metallurgical vessel, connections (4) on the slag stopper are simultaneously connected to associated connections on the metallurgical vessel.
