Components and Design of Channel Inductor Furnaces
An induction channel furnace consists of a tiltable furnace vessel with refractory lining onto which an inductor or several inductors are flange mounted. This article includes a discussion on the design for holding and dosed-pouring of the iron melts, design for melting the materials, and refractory lining of furnace vessel. It provides information on the structural changes and refractory lining of channel inductors. The article also includes a discussion on power supplies deployed in channel inductor furnaces: line-frequency power supply for melting iron, and converter power supply for melting nonferrous metals. It concludes with an overview of the inductor cooling circuit.
