摘要：

For the flatness defects of high strength steel, the relationships among the rolling shape, cooling export shape and final strip shape were analyzed. Then, the cooling temperature drop of strip steel in the cold layer zone and the flow deviation on both sides of the cold tube were measured by thermal imager, and it was determined that the uneven cooling problem of laminar flow was the cause of final strip shape. The experiment study shows that by optimizing the uniformity of the flow rate distribution of cold tube, adjusting the angle of the side nozzle, optimizing the spray sweep effect on the side and changing the upper and lower water ratio of the cold layer, the uniformity of strip steel in the cold layer zone is enhanced, and the quality defects of hot rolled high strength steel sheet is improved to meet the requirements of customers.
