ABSTRACT:
A method is disclosed for melting metals in a channel-type induction furnace which has a double channel-type unit with two inductors, each inductor being located at a separate magnetic core. The method consists of variable magnetic fluxes, which induce electric current in the channels of the channel unit being generated in the cores and a through flow of metal along the channels being created. This flow is provided by reducing the hydrodynamic turbulence at the outlet of the central channel, the phase shift between the magnetic fluxes being maintained at an angle less than 90 electrical degrees. The rate of the metal flow is adjusted by changing the phase shift angle during the course of melting.
