Abstract
1. Method to empty tiltable metallurgical vessels (1), in particular steel converters, provided with a tap hole (2) in the side wall and containing molten metal on which floats a layer of slag, where the taphole is closed with a plug (3) at incipient slag outflow and where gas blowing is implemented in the vicinity of the tap hole, characterised in that a tight closure of the tap hole (2) is ensured at the latest after the end of the metallurgical operations and before the tilting of the vessel (1), by means of a plug (3) prone to being attached by the molten mass, in that the vessel is tilted, in that a bubbling gas is introduced beside the tap hole into the vessel through gas permeable elements (10), in that the tap hole (2) is closed by means of a new plug at incipient slag outflow and in that the vessel (1) is tilted back into the starting position.
