Magnetic device for induction heating thereof

Abstract

The present disclosure discloses a magnetic device for induction heating thereof that relates to the field of induction heating technologies. The magnetic device includes at least four coils that are even numbers, wherein the at least four coils are equally divided into two groups, and the two groups of coils are symmetrically arranged around an axis thereof; and a driving unit arranged on a symmetrical central axis of the coil and configured to drive a metal material to be heated to rotate. The present disclosure provides the even number of coils combined to form an annular coil device, so that a larger and more uniform magnetic field is generated in a center of the annular coil device, which can be more favorable for improving an eddy current heating effect thereof.
