ABSTRACT OF THE DISCLOSURE Combined smelting and holding furnace, primarily for aluminium alloys, comprising a vat (2) for a melt (11), the furnace having one filling-up part (4), one element part (5) and one discharge part. The furnace is designed for continuous operation in such a way that the temperature of the removed, molten metal is not lowered when the furn- ace is being refilled ; also for a reduction of oxidation of the metal. According to the invention the furnace has a closed element part (17), 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 element part. The part- ition 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.
