Method for improving thermal uniformity in induction heating processes

An induction heating workcell having a fixed solenoid coil heats parts more uniformly by aligning ferrite blocks, generally along the centerline of the coil, to improve uniformity of the magnetic field, magnetic flux, and power density. The blocks are nonconducting but have a high magnetic permeabil...

Beschreibung
Zusammenfassung:	An induction heating workcell having a fixed solenoid coil heats parts more uniformly by aligning ferrite blocks, generally along the centerline of the coil, to improve uniformity of the magnetic field, magnetic flux, and power density. The blocks are nonconducting but have a high magnetic permeability so that flux prefers to travel through the block over surrounding structure. Therefore, the blocks are flux shapers that produce the desired temperature control.
