Mill Vibration Phenomena during Cold Rolling

The simplest type of mill vibration is found in all mills It is a forced vibration due to roll eccentricity and so occurs at roll rotation frequencies These frequencies are usually lower than any of the resonant frequencies of the mill stand Therefore gauge variation is a result of the stiffness response of the mill and the material on the
