Chattering in Rolling of Advanced High Strength Steels

Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. The book highlights the latest advances in rolling technologies of AHSSs. It introduces the history, types and advances of AHSSs and their processes; proposes new theory that is applicable to the rolling of AHSSs, presents mathematical and numerical modelling of AHSSs in rolling; covers thermomechanical processing technologies of AHSSs; provides case studies on the rolling practice of the most popular AHSSs and includes other rolling-related technologies of AHSSs. The specific chapter is about the chatter in rolling mill process: an undesired phenomenon generating detrimental conditions for the plant and the quality of rolled products. Since the improvement of manufacturing processes are, in many cases, key contributors to the implementation of AHSS technologies, models of chatter phenomena in rolling mill process are showed.
