Chatter is one of the most crucial phenomenons in strip rolling, especially in the very fast operating process steps like cold rolling. Bringing mills to the maximum of their operational possibilities without entering the “chatter” areas is not only a challenging task for all producers of Aluminum and Steel strip and sheet but must also be supported comprehensively by the plant manufacturers. This paper gives an overview of the theoretical background of chatter phenomenons, components of an effective chatter management including the details of the new Genius CM analysis “Chatter Plus”, the challenges to provide a system offering multiple possibilities to analyze the related data. Additionally the Chatter Plus analysis results are actively used within the into Plant plant’s Electric & Automation system to avoid chatter marks and strip breakages.
