Zusammenfassung:	PROBLEM TO BE SOLVED: To enable reduction of a physical burden of a worker and proper heat control in a method for peeling a coating film on a steel surface by induction heat.MEANS: An induction generator 12 has an induction head 18 including an induction coil therein, and an electric winch 28 for moving up or down the induction generator 12 is provided. The electric winch 28 is provided at a balance arm 22. The induction generator 12 is suspended by a cable 42 of the electric winch 28. A sensor for detecting a surface temperature of a steel plate or a surface temperature of a coating film is provided in the induction generator 12. A moving speed of the induction head 18 moved by the electric winch 28 is controlled so that the surface temperature of the steel plate or the coating film is in a predetermined range.SELECTED DRAWING: Figure 1 【課題】本発明は鋼材表面の塗膜を誘導熱により剥離する方法に関し、作業員の体力的負担の軽減及び適性な熱管理を可能とすることを目的とする。【手段】誘導発生器１２は内部に誘導コイルを備えた誘導ヘッド１８を有し、誘導発生器１２の昇降のため電動ウインチ２８が設けられる。電動ウインチ２８はバランスアーム２２に設けられ、誘導発生器１２は電動ウインチ２８のケーブル４２によって吊り下げられる。誘導発生器１２には鋼板の表面温度若しくは塗膜の表面温度を検出するためのセンサが設けられ、電動ウインチ２８による誘導ヘッド１８の移動速度は鋼板若しくは塗膜の表面温度が所定範囲となるように制御される。【選択図】図１
