<p>A melting device (1) for aluminium and aluminium alloys which comprises a melting furnace (2) having a melting chamber (3), arranged to keep a volume of aluminium, provided with at least one burner (9) arranged for the purpose of heating and melting solid aluminium charged into said melting chamber (3), and at least one electromagnetic stirrer (11) inducing an electromagnetic field in the molten aluminium (13), thereby causing a stirring of the molten aluminium (13). The melting device further comprises a gas- supplying device arranged to supply gas comprising oxygen into said volume of molten aluminium (13) kept in said melting chamber (3) and thereby establish an exothermic reaction between the molten aluminium (13) and the oxygen. Further, the electromagnetic stirrer (11) is arranged to stir the molten aluminium (13) so that the heat generated by said exothermic reaction is spread in the melt.</p> |
