Analysis of bearing load distribution and elastic deformation of roll system for four high strip mill

• 摘要：

  To precisely analyze the bearing load distribution and its influence on the strip shape of four-high strip mill, the dynamic explicit three-dimensional elastic-plastic finite element model (FEM) was established based on ANSYS/LS-DYNA software, which includes backup roll bearings and its chock components, strip, backup rolls and work rolls. The bearing force conditions of different rolling processes such as biting stage, steady rolling stage and exiting stage were analyzed. The bearing load distribution rules of the whole rolling process were obtained. Compared to the results of the traditional FEM with rigid roll neck, the predicted transverse strip thickness distribution of the new model is much closer to the experimental result.
