Abstract: Electromagnetic separation of inclusion particles from aluminum melt only by industrial frequency current was investigated. The influence of processing variables including current density, imposed time, the types of separator on the migration behavior of inclusion particles were studied. The results show that the higher current density and longer imposed time result in higher removal efficiency. When the applied current density is 4.7×106 A/m2 and the imposed time is 40s, there are observable effects in all kinds of pipes. The electromagnetic separation from molten metal only by alternating current is feasible.
Key words: electromagnetic separation; inclusion; industrial frequency current; aluminum alloy melt
