Abstract
A meandering control method for steel strip includes: an imaging step of imaging the surface of a traveling steel strip using a line sensor camera installed between adjacent rolling mills; a meandering amount calculation step of calculating the meandering amount of the steel strip by detecting the positions of both end portions in the width direction of the steel strip from a one-dimensional brightness distribution based on the captured image; and a leveling control arithmetic operation step of arithmetically operating a roll opening difference between the operation and drive sides of the rolling mill located on the immediately downstream side of the line sensor camera based on the calculated meandering amount. The imaging is performed in a period of 5 msec or less.
