Channel Furnace Melting with Jet Flow Inductors

Melting of metal in vessels powered by channel type inductors dates back to early in this century. Until recently, iron foundries requiring 5 to 10 tons of metal per hour relied upon cupolas or arc furnaces. About 15 years ago, the coreless induction furnace began to find acceptance in this field. Now improvements in the basic design of channel induction units result in an alternative to coreless furnaces, and the examples used in this paper list the comparative equipment costs and energy costs and illustrate the potential savings that can result from the use of channel melting equipment.
