Abstract:Using the electromagnetic repulsive force resulting from the conductivity diversity between alloys and inclusions, the inclusions were removed successfully under high frequency magnetic field. The experiment materials included Al-10%Al2O3, Al-10%SiC and Al-24%Si. The aluminum alloys mixed with the inclusions were first placed in separators with different pipe diameters, then the high frequency electrical source was turned on and the output power was adjusted, finally the aluminum alloy was melted and the inclusions were separated. Moreover, the separation efficiency of each technological parameter, such as pipe diameter, particle size, magnetic density and acting time was analyzed. It is found that the spherical Al2O3 and SiC particles are more easily separated compared to the acicular primary silicon particles, and higher magnetic density and finer pipe diameter are beneficial to the separation of inclusions.
