Abstract:The effect of parameters, electrical source power, purification time and
   pipe radius on the purification efficiency of Al-24%Si hypereutectic
   alloy was investigated in an alternating magnetic field. The
   purification effect was better when the electrical source power was
   higher, the purification time was longer and the piper radius of the
   separator was thinner. The end effect occurred in the Al-melt of
   work-coils end. The separated primary Si particles incorporated at the
   separator pipe wall, and grew up into the Al-melt, which affected the
   purification effect ; but it was constrained when the diameter of
   separator pipe was 10 rnm and the power was 10 kW. The optimal effect
   was achieved when the acting time was 30 s.
