A Review on Theoretical Analyses of Rolling in Europe

Abstract

A review of works on modelling of hot and cold rolling in the European area during the last few years is presented. First, the mechanical and mathematical features of the papers reviewed are presented (rheological assumptions; friction law and contact treatment; time integration schemes; thermomechanical coupling; methods of solutions). Then the results obtained by the various research groups are presented. First hot rolling is investigated; the major problems addressed are then product geometry and thermal evolution with some applications to metallurgical evolution. Finally, papers about cold strip rolling are discussed; these mainly analyze elastic roll deformation (flattening by plane strain approaches, 3D roll bending studies) and its consequences on strip profile and flatness. © 1991, The Iron and Steel Institute of Japan.
