Abstract
Electromagnetic forces acting in channel-type induction furnaces are outlined and conditions discussed under which metal flow in the channel meets technological requirements. A mathematical model of the channel furnace is presented and a furnace model used for experimental investigations into metal flow is described. Simulation of metal flow in the axially symmetric mathematical model furnishes a characteristic value vortex efficiency - which describes the ability of a vortex to effect flow. A numerical study of the combined conical and rectangular bulge in the channel shows that with constant amperage in the channel and increasing frequency in the lower range (500 Hz) there is an unexpected increase in flow. At somewhat higher frequencies flow shows the expected decrease. The decrease in flow at rising frequency and constant channel current was confirmed qualitatively by experiment. The results obtained show that it will be necessary to continue the experimental studies using better instrumentation.
