摘要：

Three dimensional magnetic field around a cold crucible system has been analysed by using the boundary element method to get the basic information for designing a cold crucible system. From the computed magnetic field distribution, heat generation rates in the charge, the crucible and the coil were calculated. The calculated magnetic field and heat generation rates in the charge, the crucible and the coil showed good agreement with the observed ones. The axial and radial components of magnetic field are dominant in comparison with the azimuthal component. The heat generation rate in the charge increases with decreasing the gap between the charge and the crucible or with increasing the diameter of the charge under the same coil current. Energy efficiency can be improved by increasing the surface of the charge and decreasing the surface of the crucible. The distribution of heat generation rate in the charge along the axis is sensitive to the arrangement of the coil.
