Abstract
Different mathematics and physical models for analyzing the electromagnetic shaping of liquid metal were reviewed. On the basis of the theory of electromagnetic shaping, the concept of dual-frequency electromagnetic shaping of liquid metal was presented, which mean that the one frequency electromagnetic field is used to melt the solid metal above its melt temperature and the other frequency electromagnetic field is used to make the liquid metal to a final shape. The electromagnetic pressure produced by the counteract of magnetic field in coil and the eddy current in liquid metal is mainly determined by the magnetic flux density on the surface and its dissipation in the liquid metal. At last, some problems for electromagnetic shaping complex shapes were discussed and the methods for solving these problems were proposed.
