ABSTRACT:
A metallurgical furnace has a cover (20) for a vessel (10) and a charging device (30) for charging material that will be melted in the vessel. The charging device has a rotatable retaining means (31) and a projection (40) is provided at a charging opening (42). The furnace has a maximum filling level (H2) and the rotatable retaining means is pivoted into the projection for the charging operation. The pivotable range of the retaining means does not extend below the maximum filling level (H2). At least two self-supporting material baskets (32) can be positioned in a removable manner above the projection (40), and each comprises an inner chamber that can be closed on the lower side thereof by the retaining means (31) and a volume (C) for receiving the charging materials. A change device (33) interchanges and positions the material baskets (32).
