electromagnetic separation of aluminum

A novel scheme about the continuouselectromagnetic purification of aluminummelt was put forward based on the utilization of a squareseparation pipeand a 50 Hz alternating current to produceelectromagnetic force. It is experimentally found that withelectricalcurrent of 400 A/cm 2, it takes only 10 s to remove 95% inclusion fromaluminum melt. Comprehensive numerical simulations were …
