Coil Failures: pt. 10 Contactless Inductors
June 1st, 2010
In other applications such as strip or plate heat treating and coating (galvanizing, galvannealing, galvaluming, nonmetallic coating, and paint drying, for example), the ability to move the induction coil from the heating position to an off-line position is considered an important system requirement. Solenoid induction heaters with water-cooled “doors” are sometime used for such applications. Article discusses patented doorless induction coils that allow increasing coil life and eliminating the maintenance problems associated with high-frequency current interrupting a doored inductor.
