Superconducting induction heating system for production line

A superconducting induction heating system for a production line comprises a superconducting magnet system, an iron core, an iron yoke, gradient adjustable iron yokes, a rotating motor, a mechanical transmission system, a control system, a conveying system, a supporting system, a PLC control system, a four-jaw chuck, a metal workpiece to be heated and heating air gap spaces. The iron yoke placed on the upper side of the iron core and the gradient adjustable iron yokes placed on the single side form heating air gap spaces of different configurations, and the heating air is gathered in the heating air gap spaces. The metal workpiece is dragged by the rotating motor, the mechanical transmission system and the control system to rotate in the heating air gap spaces, magnetic induction lines generated by the superconducting magnet system in the heating air gap spaces are cut, eddy current loss is generated, joule heat is generated, and therefore the metal workpiece is heated. The heating air gap spaces of different configurations are formed through the gradient adjustable iron yokes, different heating gradients are provided for metal workpieces with special heating requirements, and convenience and high efficiency are achieved.
