Abstract
Rolling mill should have high operational reliability to avoid unscheduled shutdowns, since it significantly affect production. During the operational process high levels of vibration in certain production velocities were observed, causing Chatter Marks. In order to understand the dynamic behavior of these equipment in different conditions, and consequently to propose actions avoiding such events, field testing and numerical simulation were performed. Field testing highlighted vibrational problems caused by failures in internal components, as well as operational deflection forms related to each excitation source due to these events. Correlation of results with those obtained numerically showed their impact on the quality of the material produced. Vibrational levels and resulting problems were attenuated after application of suggested recommendations.
