主　　题：metallurgical-grade silicon vacuum induction refining multi-fields coupling numerical simulation 

摘      要：The temperature and velocity distribution of melting pool fields is very important effect to the silicon purification in vacuum induction furnace.A numerical model for the electromagnetic-thermal-hydrodynamic coupling fields have been developed by using the finite element method(FEM)and a 2D numerical simulation for electromagnetic、 temperature and velocity fields of metallurgical-grade silicon melting in vacuum induction furnace were performed with a software Multi-physics Comsol 3.5a in this *** results showed that the temperature field was dependent observably on input power of coils and induction heating times and the maximum temperature gradient in melting pool was 215K in holding *** the silicon molted gradually a clockwise vortex was come into being for electromagnetic stirring in the smelting *** variation of velocity field in melting silicon is mainly influenced with the change of the current intensity and power *** numerical predications of temperature distribution are in good agreement with experiments.
