Abstract
The disclosure relates to a melting furnace, for example a two-chamber furnace, for the recovery of aluminum from aluminum scrap. This has a scrap chamber (2), with a dry hearth (6), the surface of which provided for receiving aluminum scrap is arranged above the surface of an aluminum melt (7) located in the scrap chamber (2) during operation of the melting furnace (1), and a heating chamber (3), which has at least one burner (9) for fuel firing, the heating chamber (3) and the scrap chamber (2) being separated from one another by a partition wall (11), the partition wall (11) having at least one opening (12) for recirculation of the aluminum melt (7) between the heating chamber (3) and the scrap chamber (2). Further, a refractory lining of the surface of the dry hearth (6) and/or a refractory lining of the inner wall of the scrap chamber (2) in the region of the dry hearth (6) have channels (18) which can be acted upon by hot gas and are designed to absorb heat from the hot gas and to release it to the aluminum scrap located on the surface of the dry hearth (6) for its thermal pretreatment.
