Document Type and Number:
WIPO Patent Application WO/2020/103452
Kind Code:
A1
Abstract:
An electromagnetic induction heating device for surfacing and preheating a rotor surface of an internal mixer, comprising a rotor to be welded (1). A plurality of electromagnetic induction heating devices (3) are installed at an inner part of the rotor to be welded by means of support legs (2), and the electromagnetic induction heating devices are distributed annularly at equal intervals at the inner part the rotor to be welded. Two ends of an electromagnetic induction heating device are respectively mounted with a left claw disk (5) and a right claw disk (6) by means of claws (4), and a protective pipeline (7) is axially arranged in the middle of the right claw disk. The electromagnetic induction heating device has a fast heating speed, high efficiency, an extremely low metal burning rate, and a low heating cost, and employs closed-loop control. The induction heating may perform real-time and accurate automatic control according to a current state of a workpiece being heated.
