摘要

Induction channel furnace (ICF) and channel type induction heating tundish (IHT)using electromagnetic induction phenomenon are widely applied to metal melting, refining, temperature maintenance, overheating and continuous casting of nonferrous and ferrous metals. It has low power consumption and noise, high quality of molten iron and high thermal efficiency, but it has short-operating life. Due to failures of inductor and other causes, cooling and shrinkage of channel loop caused the break and the high temperature distribution caused premature erosion of refractory. This paper proposes a new Omega-type channel loop of single-phase ICF for steel melting, and determined optimum design parameters of channel loop using Taguchi method and simulation of the commercial software COMSOL Multiphysics and ProCAST to extend the operating life of ICF. The results of simulation and field test data demonstrate full possibilities of intermittent operation and life extension of channel loop over 140 cycles, so the proposed new structure of channel loop can be satisfactorily applied for steel melting and superheating using channel type induction heating technology.
