Superconducting induction heating system for production line

Abstract

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.

Description

technical field [0001] The invention relates to a superconducting induction heating system used in a production line, which belongs to the field of metal heat treatment, and can be used in the process of continuous casting and steelmaking, including metal smelting, casting and hot rolling processing of nonferrous metals. Background technique [0002] my country is a big country in metal smelting and deep processing, which consumes a lot of energy, accounting for more than 30% of the country's energy consumption. The traditional induction heating device uses a magnet coil wound with copper material, and an alternating current is passed into the magnet, and the metal workpiece is inserted into the copper Inside the coil, the alternating current generates an alternating magnetic field and eddy current loss in the metal workpiece, thereby heating the metal. This type of heating equipment has low heating efficiency, shallow heat penetration depth, and the electrothermal conversion ...
