METHOD FOR PEELING OFF COATING

摘要

PROBLEM TO BE SOLVED: To enable reduction of physical burden on a worker and proper heat control in a method for peeling off a coating film on the surface of a steel material by induction heat.SOLUTION: An induction generator 12 includes an induction head 18 provided with an induction coil therein, and an electric winch 28 is provided for lifting and lowering the induction generator 12. The electric winch 28 is provided to a balance arm 22, and the induction generator 12 is hung by a cable 42 of the electric winch 28. A sensor for detecting the surface temperature of a steel material or a coating film is provided in the induction generator 12, and the movement speed of the induction head 18 by the electric winch 28 is controlled so that the surface temperature of the steel material or the coating film is maintained in a predetermined range.
