PROBLEM TO BE SOLVED: To provide a control method of a rolling mill capable of suppressing the occurrence of meandering in a tail end part of a rolled material, a control device of a rolling mill, and a manufacturing method of a steel plate.SOLUTION: A control method of a rolling mill includes: a tension measurement step of measuring a width direction deviation of tension of a rolled material; a camber amount measurement step of measuring a camber amount of a tail end part of the rolled material; and a control step of calculating a leveling amount of the rolling mill by using the width direction deviation of tension of the rolled material measured in the tension measurement step and the camber amount of the tail end part of the rolled material measured in the camber amount measurement step, and controlling the rolling mill based on the calculated leveling amount.SELECTED DRAWING: Figure 2 |
