Original Kurzfassung:
Temper rolling represents the final stage in the production chain of cold rolled flat steel products. During temper rolling, material and surface properties as well as flatness of cold rolled strip are tailored and customised. To generate the desired surface structure on uncoated or zinc-coated steel strip, textured work rolls are utilized. Based on the knowledge resulting from extensive temper rolling tests [1], FEM-simulations [2, 3]have been established as an important tool for the quantitative description of such rolling and stamping processes.
For the accurate and reliable simulation of temper rolling processes, special emphasis has to be put on typical characteristics, such as a small contact length between work roll and strip as well as pronounced elastic roll flattening resulting in a non-circular arc roll contour. The FEM-models presented recently in [4] and also in this context were
developed by utilizing the commercial FEM-package Abaqus [5] and take into account both uncoated and zinc-coated elasto-plastic steel strip and elastic work rolls. Highly
sophisticated submodelling techniques are applied, in order to reach reasonable calculation time and storage capacities for 3D models. Submodelling techniques divide the whole process simulation into two parts. The first calculation step is a coarse large scale analysis of the rolling process e.g. with a smooth work roll surface and takes into
consideration elastic work roll flattening. Currently, a regularised Coulomb friction law is incorporated to account for the global effects of the roughness transfer. Based on the results of the coarse global analysis, the subsequent simulation step performs a detailed local analysis on the length scale of the roughness structures. In this simulation step, only a small cut-out of work roll and strip with detailed modelling of the roughness structures is analysed.
