Abstract

During the flat rolling process (cold or hot), the strip flatness and thickness profile are highly influenced by the interaction effects between strip and work rolls. To understand and analyze these effects a new modeling concept was developed. Within this concept, the tool simulations are separated from the process simulation. With the help of an automatic coupling module, the influences of the tool effects are realized within the process simulation. With this modeling concept, three types of interaction phenomena are studied and validated using experiments: elastic roll effects during the cold rolling process, work roll thermal effects during the hot rolling process and tribological effects (abrasive wear) on the process simulation. It was also shown that, compared to the single FE model, this modeling concept is relatively faster and suitable for large 3D models without losing the quality of the predicted results.
