High performance induction melting coil

摘要

An improved induction melting coil apparatus encapsulated with homogeneous inserts for controlling the direction of inductor flux density is disclosed. The inserts are relatively thick and rigid members which provide a low reluctance path within which the magnetic field travels while inhibiting inductive coupling of the magnetic field with surrounding auxiliary components. The inserts can be easily formed or machined into any desired shape for effectively encapsulating virtually any type of coreless induction melting coil.
