| Popis: | Pushed forward by mill complexification and harder product quality requirements, the mathematical treatment has evolved into very complex, multi-coupled models: roll deformation, thermal transfer, lubrication, and oxide scales are a few examples. The diversity of rolled products and rolling mills makes rolling process modelling a vast field indeed. Beyond general, necessarily very costly models, partial descriptions are developed for more targeted goals. Three methods share the market: the Slab Method (SM), the Upper Bound Method (UBM), and the Finite Element Method (FEM). A few modelling strategies based on the above three are described, providing accurate solutions in an industry-compatible computation time: steady-state FEM modelling; faster 2D SM with large roll flattening to build thin sheet or temper rolling force models; low-cost 3D roll stack deformation package for profile/flatness of sheets; FEM results-based UBM models of width variations in the Tandem Cold Mill; post-bite profile and flatness evolution (interstand behavior); FEM description of oxide scale behavior in descaling; SM with modern lubrication modelling. Evolutions of rolling processes are questioned to point to new demands on modelling and how to answer them. |
