A hybrid magnetic circuit superconducting induction heating device based on a split iron core

Abstract

The application discloses a hybrid magnetic circuit superconducting induction heating device based on a split iron core, which includes a permeable core, a superconducting coil arranged around the permeable core, and a plurality of parallel iron yokes distributed circumferentially around the permeable core , the magnetically permeable core is composed of a plurality of sub-cores cut along the longitudinal direction of the cylindrical iron core; The number of iron yokes is equal to the number of divided iron cores, each iron yoke corresponds to a divided iron core, and the upper end surface / lower end surface of each iron yoke is connected to the upper magnetic conductive plate at the upper end of the corresponding divided iron core / lower end of the lower end There is a first air gap between the side walls of the magnetic conductive plate, and the first air gap is used to place the workpiece to be processed; the workpiece to be heated can rotate under the action of an external force to generate an induced current to heat the workpiece to be processed. The hybrid magnetic circuit superconducting induction heating device based on the split iron core provided by the present application has an independent anti-interference magnetic circuit and thus has better heating regulation characteristics.
