Description
Summary:The corresponding objectives and principles of the intermediate roll contour design are proposed to improve the strip edge drop problem in the process of 18-High mill production and enhance the regulation ability on strip shape. The intermediate roll contour is designed using the particle swarm optimisation algorithm to satisfy the production requirements. The elastic–plastic coupling finite element model of roll system–rolling piece integration is established, the application effect of the new roll contour is verified, and the regulation ability on strip shape under the new roll contour is analysed. Results show that, compared with the original roll contour, the strip edge drop phenomenon is remarkably improved. The regulation ability on strip shape is evidently improved compared with that of the original roll contour. The regulation ability on strip shape of the intermediate roll shifting is stronger than that of the intermediate roll bending force under the new roll contour. Finally, combined with field data of rolling, the finite element model is verified on site. The simulation and measured values are high, and the error is within 10%. The research results can provide a good theoretical basis for the improvement of the intermediate roll contour and improvement of the regulation ability on strip shape of 18-High mill.
