“…Analysis methods and models with low computational cost and high enough accuracy need to be taken into account when analyzing the rolling mill-strip deformation behavior. The model separates the roll stacks and strip steel and applies appropriate conditions for analysis, and the results are usually checked by using the finite element model and test method [12][13][14]. A boundary integral method is commonly used to analyze the deformation of the roll system and obtain reliable results [15].…”

Due to the requirement of magnetic properties of silicon steel sheets, producing high-precision size strips is the main aim of the cold rolling industry. The tapered work roll shifting technique of the six-high cold rolling mill is effective in reducing the difference in transverse thickness of the strip edge, but the effective area is limited, especially for a high crown strip after the hot rolling process. The six-high mill with a small work roll size can produce a strip with higher strength and lower thickness under a smaller rolling load. At the same time, the profile of the strip can be substantially improved. By advancing a well-established analytical method, a series of simulation analyses are conducted to reveal the effectiveness of a small work roll radius for the strip profile in the six-high cold rolling process. Through the analysis of flattening deformation and deflection deformation on the load, the change rule of the strip profile produced by the work roll with a small roll diameter can be obtained. Combined with theoretical analysis and industrial experiments, it can be found that the improvement effect of the small work roll radius on the profile of the silicon strip is as significant.

“…Thermo-mechanical coupling is not activated here. -A 3D semi-analytical elastic roll deformation model called Tec3, fully described in Hacquin et al [21]. It combines roll bending based on Timoshenko's beam model, roll flattening based on Boussinesq equations for a semi-infinite solid arbitrarily loaded on its surface, Hertz contact theory for the work roll/back-up roll contact.…”

Numerical Treatments of Slipping/No-Slip Zones in Cold Rolling of Thin Sheets with Heavy Roll Deformation

2015

Abstract:In the thin sheet cold rolling manufacturing process, a major issue is roll elastic deformation and its impact on roll load, torque and contact stresses. As in many systems implying mechanical contact under high loading, a central part is under "sticking friction" (no slip) while both extremities do slip to accommodate the material acceleration of the rolled metal sheet. This is a crucial point for modeling of such rolling processes and the numerical treatment of contact and friction ("regularized" or not), of the transition between these zones, does have an impact on the results. Two ways to deal with it are compared (regularization of the stick/slip transition, direct imposition of a no-slip condition) and recommendations are given.

“…They noted various differences between the FEM solutions and the classic solutions when studying the effects of strip width, roll diameter to length ratio, and rolling load intensity. Hacquin also studied roll end effects upon enhancement of Berger's strip profile model, which was an improved version of Shohet's original influence coefficient model (Hacquin et al, 1998;Berger et al, 1976). These noted geometric effects on the flattening characteristics between rolls are accommodated by the foundation stiffness moduli formulation of the presented method.…”
