Abstract
A method of cooling control for a steel plate, a cooling control device, and a method of manufacturing a steel plate, which adjust an upper/lower water ratio and prevent C-warping during cooling. The method of cooling control includes: determining an upper/lower water ratio of a steel plate being cooled wherein at least one of a C-warping amount and a curvature is within a target permissible range, based on a past operating condition, a past upper/lower water ratio when cooling under the past operating condition has been implemented, and at least one of a past C-warping amount and a past curvature measured by a shape measuring meter at an outgoing side of a cooling zone when the cooling under the past operating condition is implemented; and adjusting an amount of cooling water to be blown onto the steel plate to reach the upper/lower water ratio.
