Abstract:The coupling field of electromagnetic toree and flow was simulated tor the self-developed double-loop induction furnace. The results show that under the vertex electromagnetic field in channel, there exist the flow along the channel axes and the secondary circulation flow in the inlet and outlets of the channel. The magnetic flux density of liquid metal surface is in inverse proportion to the current frequency and in direct proportion to the input volt/current. The maximum electromagnetic force is in direct proportion to the square of magnetic flux density and in inverse proportion to the current frequency. The average flow rate along the. channel axes of the molten channel is in direet proportion to the magnetic flux density and in inverse proportion to the square root of the density of the molten meta
