In a method and a device for melting down metal-containing material, preferably fine-particulate metal-containing material, such as sponge iron, in a metallurgical melting furnace ( 1 ), wherein, in an interior space ( 11 ) of the melting furnace ( 1 ), a metal melt ( 5 ) and a slag layer ( 6 ) floating on top of the metal melt ( 5 ) are maintained, the metal-containing material is added by means of a supply means dipping into the slag layer ( 6 ) and energy is added in the form of electric arcs ( 14 ), the metal-containing material is charged directly into the central region (Z) of the melting furnace ( 1 ) by means of at least one charging tube ( 8 ) exclusively serving for conveying material via the charging tube outlet ( 9 ) of the same, the electric arcs ( 14 ) are directed obliquely towards the metal melt ( 5 ) against the central region (Z) of the melting furnace ( 1 ) and the metal-containing material is melted in the slag layer ( 6 ) and a mixed process slag-metal melt is maintained in the region of the charging tube outlet ( 9 ). |
