Abstract: In a decision control device of a control system, a predetermined pass schedule is decided by adjusting the rolling force per unit width at a last stand of a hot finishing tandem rolling mill to cause the edge profile on the outlet side of the last stand to fall within an allowable range based on the relationship between a strip crown and the edge profile on the outlet side of the last stand with respect to the rolling force per unit width and a strip shape control parameter, obtained regarding the last stand, and adjusting the strip shape control parameter of the last stand to cause the strip shape on the outlet side of the last stand to fall within an allowable range and cause the strip crown to become a predetermined value or smaller.
