超電導磁石を利用した電磁分離装置開発の検討

The separation method using electromagnetic force is receiving attention as an elimination method for the removal of impurities from molten metal. In this study, the relation between electromagnetic force and the motion of particles in molten metal was discussed through experiment and calculation using metals with low melting temperatures. Electromagnetic separation was examined under conditions which were decided by the results of calculations (average flow velocity: 0.1 m/s, electric current density: 2.1×10⁴ A/m², magnetic flux density: 10 T).The relation between particle size and separation efficiency can be obtained through calculation. It was successfully demonstrated that the insulating lead balls in metals melted at low temperature could be separated by electromagnetic force.
