Abstract:
The disclosure relates to a method for producing feedstock in piece form from metal, in particular aluminium and/or aluminium alloys, for a metal-casting installation, in particular aluminium-casting installation, in which scrap parts of metal, in particular of aluminium and/or aluminium alloys, are sorted on the basis of their alloying constituents and/or alloy contents and subsequently, on the basis of an alloy to be produced in the feedstock, the scrap parts are mixed into a composition having a homogeneous distribution of the alloy and fed to a press, in which the scrap parts of the composition are subjected to a pressure that compresses the scrap parts while generating a temperature, wherein, as a result of the application of pressure, the scrap parts are heated up to the transition temperature between solid and liquid of at least some of the scrap parts and/or the alloys and/or alloying constituents thereof before the feedstock is discharged in a specific geometrical form.
