In the process of electromagnetic separation of aluminum melt impurities easy to produce eddy current eddy current will reduce the effect of separation of impurities in order to curb the eddy current and improve the separation effect of impurities in different magnetic induction intensity, different separator and magnetic field relative position, different induced current Density and other experimental conditions to observe the surface state of the aluminum melt · The experimental results show that the eddy current generated in the aluminum melt with the magnetic field intensity increases violently with the aluminum melt surface and the magnetic pole perpendicular to the surface of the vertical distance decreases and increases with Increasing and increasing the horizontal current density in the aluminum melt · Eddy current generation can be suppressed by adjusting the magnetic field and changing the separator structure
