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).

Abstract: In a process for at least temporarily simultaneously subjecting a molten metal (5) in a metallurgical vessel (3) to the action of a gas and fine-grain solid materials, with a water-cooled first lance (17) for supplying the gas, in accordance with the invention the solid materials are supplied in the form of a conveyor stream (27) by way of a second lance (19). The solid materials are supplied in such a way that, after leaving the outlet opening (25) of the second lance (19), they are deflected by the gas (29) issuing from the outlet opening (23) of the first lance (17) and are supplied with said gas to the molten metal (5).
