Superconducting induction heating device for simultaneous heating of multiple workpieces based on split iron core

Abstract

The application discloses a superconducting induction heating device for simultaneously heating multiple workpieces based on a split iron core, which includes a permeable core, a superconducting coil surrounding the permeable core, and an iron yoke. Wherein, the magnetically permeable core is composed of a plurality of divided iron cores cut longitudinally from the cylindrical iron core; the upper end of each divided iron core is correspondingly provided with an upper magnetically conductive plate, and the lower end of each divided iron core is correspondingly provided with a lower guide plate. Magnetic plates; the number of iron yokes is the same as the number of sub-iron cores, the upper end face / lower end face of each iron yoke is connected with the upper / lower magnetic permeable plate of the corresponding sub-iron core, and each iron yoke is provided with a gas The air gap is used to place the workpiece to be heated; the workpiece to be heated can be rotated under the action of an external force to generate an induced current to heat the workpiece to be processed. The device provided by the present application can simultaneously heat multiple workpieces to be heated and increase the heating efficiency of the workpieces to be heated. The split iron core in the device constructs an independent magnetic circuit so that the device has more stable heating adjustment characteristics.
