PROBLEM TO BE SOLVED: To provide a method for controlling a speed of a press apparatus for a width direction in hot rolling, wherein the method can shorten the time of the width direction rolling by the press apparatus and can enhance the ability of the press apparatus to a maximum. SOLUTION: A rolling torque in the width direction rolling is estimated from a reduction amount of the width direction rolling, etc., and the rotational speed of a motor 11 for driving a press die 12 is set to a maximum speed which can generate the estimated rolling torque.
