Abstract
A meandering control device and hot rolling equipment suppress a meandering amount of a hot-rolled steel strip. A roll opening degree difference between an operation side and a driving side in an i-th rolling machine computed in a leveling control computation step (step S) in the meandering control method, satisfies the roll opening degree difference between the operation side and the driving side in the i-th rolling machine (Fi) by Expressions (1), (2), and (3) in a control section j, in a case where the control section j is set when a tail end portion (Sa) of a traveling hot-rolled steel strip () is present between a j-th (j≤i−1) rolling machine (Fj) and a (j+1)th rolling machine (Fj+1) counting from a rolling machine (F) installed on a most upstream side.
