An unexpected failure of the work rolls and driveshafts operating on the first roughing stand occurred in the early morning hours, resulting in significant equipment damage and downtime. A condition monitoring system was being utilized to measure the transient torsional vibration but did not provide early warning signs of the failure. The monitoring system did, however, reveal that the failure was not caused by high amplitude or oscillating torques, typically the culprit of such occurrences. The detailed analysis that followed showed the origin of the failure occurring in the work roll.
