Channel Melting Furnaces

Induction Channel Melting Furnaces

Induction channel furnaces are designed to fit most ferrous alloy foundry needs and are most well known for their continuous melting capabilities, maximum efficiency, flexibility (they can be used as melters, holders, off-peak melting, and have the advantage of holding large volumes of metal required for large or continuous casting), precise temperature control, low operating costs, and clean, quiet working conditions.

Channel furnace designs are typically configured in a vertical or drum layout. Where in a coreless furnace, the power coil surrounds the crucible, in a channel furnace, the induction field is concentrated around a channel loop housed within an inductor. This loop is attached to the uppercase (upper body), creating an induction field to heat colder molten metal within the channel loop. The inductor is the heart of a channel furnace and must be extremely reliable and predictable.
