Cold Mill Modeling
During strip rolling, an initial strip shape undergoes a transformation starting from a crowned initial shape. Depending on mechanical and thermal effects in the rolling procedures, a more or less convex or even concave shape is attained. The present model allows the calculation of all local quantities of the rolling process and the exit strip shape using detailed modeling techniques of the rolling process. The model is a further development of an analysis presented previously, with a variety of enhancements implemented in its present form. A sophisticated submodel for the 3D elastic work roll deformation based on Boussinesq's problem is implemented, as well as a finite-element technique for the deflections of work and backup rolls. The model will be presented with results for hot and cold rolling, as well as comparisons with results of rolling experiments.
