Combined smelting and holding furnace, primarily for aluminium alloys, comprises a vat (2) for a melt (11), the furnace having one filling-up part (4), one heat-emitting element part (5) and one discharge part (6). The furnace is designed for continuous operation in such a way that the temperature of the removed, molten metal is not lowered when the furnace is being refilled; also a reduction of oxidation of the metal is achieved. The furnace has the closed heat-emitting element part (5), separated from the filling-up part via a partition wall (22, 23) which has a lower part (22), made from a heat-insulating material and creating, at the bottom of the vat, a passage (21) through the smelt between the filling-up part and the heat-emitting element part. The partition wall also has an upper part (23). constructed from a heat- conducting material to radiate heat from the element part to the filling-up part in order to preheat material entering the furnace. <IMAGE> |
