Abstract

Apparatus for supplying a molten metal (5) in a metallurgical vessel (3) with a gas and fine-grain solid materials comprising a water-cooled first lance (117) for the supply of the gas and a second lance (119) for the supply of the solid materials. The supply of the solid materials is effected in such a way that, after leaving the outlet opening of the second lance (119), the materials are deflected by the gas (127) issuing from the outlet opening of the first lance (117), and are fed with said gas to the molten metal (5). The lances are inserted through the side wall of the vessel (3).
