摘　　要：为提高济钢1700层流冷却过程中带钢冷却的均匀性,减小带钢冷却不均带来的附加残余应力,建立了层流上下水量关系和侧喷的数学优化模型,对层流上下水量配比和侧喷角度两个关键参数进行了优化,根据优化结果制定了相应的层流标定标准并在现场进行了应用。结果表明,优化后的层流上下水量和侧喷参数能够改善带钢延厚度和宽度方向冷却的均匀性,减小了层流带水和各类板形不良现象。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.
