Abstract
The present invention relates to a method of arranging and setting spray nozzles in a cooling apparatus comprising a plurality of pairs of constraining rolls for constraining and conveying a hot steel plate and one or more lines of spray nozzles between the pair of constraining rolls, each line having a plurality of spray nozzles and is disposed in a direction perpendicular to processing, and to the cooling apparatus and the method of cooling. The invention is characterized in that the spray nozzles are arranged such that a distribution of values ∫Pbetween two edges of the steel plate in the direction perpendicular to processing is not less than 80% of its highest value, with P being cooling water impact pressure on the cooling surface, ∫Pbeing the value of n power of P integrated in the processing direction between the pairs of constraining rolls, and 0.05≦n≦0.2.
