<p>The invention provides a manufacture method and a rolling device for a difference thickness plate. The difference thickness plate with the plate thickness changing at very small intervals in the long side direction of rolled materials is reliably manufactured. The manufacture method is characterized in that, the difference thickness plate with the plate thickness changing at very small intervals in the long side direction of rolling materials is rolled by a rolling machine (1) provided with a pair of rollers (2, 2), wherein, in order to realize the plate thickness change Delta h(x) at the output side of the rolling machine (1), when the rolling machine (1) is about to perform rolling or performs heating of the rolled materials (W) in the long side direction in rolling, the plate temperature of the position corresponding to the plate thickness change Delta h(x) is changed by Delta T(x), and rolling of the rolled materials (W) after change of the plate temperature is performed, thereby manufacturing the difference thickness plate.</p> |
