Abstract：In order to improve the evenness of cooling strip and reduce the accessional residual stress of laminar cooling system of 1 700 mm hot tandem mills of Jinan Steel, mathematical optimization models of up-down water distribution and side spray of the laminar cooling system are built by which the key parameters of up-down water distribution and side spray angle are optimized. The corresponding scaling standard is built and used in the production. The application result indicates that the optimized up-down water distribution and side spray angle improve the evenness of cooling strip toward thickness and width directions and redundant water and various shape problems are reduced clearly.
