Mill Vibration Phenomena during Cold Rolling

Mill Vibration Phenomena during Cold Rolling. All machines vibrate during operation. However, only a few of these vibrations cause problems to the product or the machine itself. Typically, the most damaging vibrations involve a natural resonance of the machine which significantly increases the motion of critical components. Rolling mill vibration

THE VIBRATION OF COLD ROLLING MILL F5 UNDER MULTI

Serious vibration occurred on the F5 stand when producing thin strips on a 1550 cold tandem mill. The field test showed that the dominant frequency of the vibration is 144 Hz, which was close to the natural frequency of the F5 stand. Moreover, there were many excitation frequencies in the strip excitation spectrum and the servovalve pressure spectrum of the screwdown system.
