“…An important geometric requirement is crown, wherein the thickness varies through the width of the strip. Crown is associated with the roll deflection due to the separating forces developed between the strip and the work rolls, causing the deformed rolls to not create a perfectly rectangular gap, but one that is curved from the top and bottom side (work roll sides) and as a result defining the geometry of the strip [1][2][3][4][5][6][7].…”

“…In the production environment, the bending set point is predetermined and defined during the pass schedule design [1]. Many researchers have utilized analytical and numerical modeling techniques in the effort to predict the work roll bending [1][2][3][4][5][6][7]. Guo (1989) [2] implemented a simple model calculating the work roll bending for each individual schedule.…”

“…Gautam [19] correlated the deflection variation of a 2-high rolling mill with the reduction percent for different steel properties. Shigaki et al [20] coupled a commercial FEM model with a Multi-Slab model for strip deformation in order to predict the roll stack deflection. Sun et al and Linghu et al [3,14] employed an elastic-plastic FEM model to determine the work roll bending forces, intermediate roll bending forces and intermediate roll shifting on a CVC 6-High mill under certain rolling conditions for pass schedule strategy allocation.…”
