Abstract
A system which provides an improved design capable of removing liquid phase inclusions by combining a filter and an electromagnetic separation device through the addition of baffles to a chamber where molten metal is flowing under the influence of an applied electromagnetic field. The placement and the shape of the baffles reduces vorticity effects of the magnetic field in each of the baffled compartments and eliminates the convective flow resulting from the electromagnetic force in order to trap inclusions against the walls of the baffles.
