Abstract
An induction heating method for a metal strip is provided to heat a continuously conveyed metal strip using an induction heating device disposed at a first position on a pass line. The induction heating method includes a step of detecting a displacement from a predetermined datum line of a width direction center line of the metal strip at a second position on the pass line that is different from the first position, a step of computing an estimated displacement of the width direction center line of the metal strip at the first position by temporal and spatial extrapolation of the displacement based on a function expressing a time series of changes in the displacement, and a step of controlling a relative positional relationship between the induction heating device and the metal strip in a width direction of the metal strip based on the estimated displacement.
