Automatic and continuous alloying of iron in Al alloys through the charge-well of an electromagnetic pump

摘要

Iron alloying is an important processing step in the production of aluminium alloys, especially if these are consumed for the production of highly demanding surface quality end-products (thin gauge aluminium foils, lithographic and high bright sheet, etc). Various tabletted or briquetted iron additives for alloying aluminium have been in use for many years for manufacturing high-quality aluminium alloys in applications such as rolling ingot for foilstock and canstock, billet for precision extrusions and high-quality foundry casting alloys. Current trends in improving the melting rate and melting recovery of aluminium scrap and achieving a uniform distribution of alloying elements favour the development of advanced alloying additives with significantly higher dissolution rates and recovery level.
