| Abstract: | According to the thermal crown and wear calculation method of work roll in hot strip mill, combined with the theory of roll elastic deformation and metal plastic deformation, the calculation models of on-line roll profile and dynamic loaded roll gap were established based on field application and model parameter optimization. According to the actual rolling scheme, the higher calculation accuracy of the model is verified compared with the measured results and the calculation model can meet the need of engineering calculation and analysis. In addition, the influences of on-line roll profile and unsmooth surface on outlet strip profile were calculated and analyzed, and the optimization methods of strip profile were proposed, which provided theoretical basis for improvement of the outlet strip shape quality in hot strip mill. |
