Study of Metal Quality and Melt Yield from Remelts of (i) Turnings AA3005 and (ii) Coil AA3003

Abstract:

It is important for aluminum producers to predict metal quality and melt yield when scrap is remelted. Therefore, these parameters are studied in individual remelt experiments with (i) Turnings AA3005 and (ii) Coil AA3003 as scrap, as a function of percent added scrap up to 33 %. To ensure same melting conditions the scrap is melted in crucibles inside a Morgan resistance furnace, measuring temperature and hydrogen. Bifilm index is used as a measure of metal quality. The results indicate that the addition of scrap (up to 33 %) does not alter metal quality. Melt yield is however affected, with a metal recovery of around 90 % for the different types of scrap.
