Title:
INDUCTION HEATING TYPE HEAT TREATMENT DEVICE FOR WOUND CORE AND HEAT TREATMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/131131
Kind Code:
A1
Abstract:
This heat treatment device is formed from: a magnetic core 7 which is disposed so as to penetrate through the inside of one or more wound cores 1, each formed into a closed circuit by winding a metal foil body into a coil shape and by electrically connecting winding ends 3, 4 of the coil together by means of an electrical connection means 5; and a heating coil 8 which is wound on the outer side of the outer periphery of the wound core 1 so as to enclose the wound core 1, and which is configured to induce an induction current 6 in the wound core 1 by applying a fluctuating current and to heat the wound core 1 using the induction current 6. Because of this, long objects and multiple products can be uniformly heated, and rapid heating can be achieved for improved productivity and reduced treatment time.
