A plate manufacturing method capable of substantially reducing cold leveling by first performing leveling process and then performing cooling process in a manufacturing process of a plate, thereby securing flatness of the plate after finishing final accelerated cooling process is provided. In a method for manufacturing a plate in a plate rolling facility comprising a rolling mill, an accelerated cooler and a hot leveler, a method for manufacturing a plate excellent in flatness comprises the steps of: passing a steel plate rolled in the rolling mill through the accelerated cooler without water injection, and hot leveling the steel plate passing through the accelerated cooler; accelerated cooling the steel plate while transferring the hot rolled steel plate in a reverse direction to the front of the accelerated cooler and retransferring the steel plate in a forward direction; and hot leveling the accelerated cooled steel plate. |
