Working-Stand Equipment Vibrations of Continuous Cold Rolling Mills during the Production of Thin Strip Products

Resumo

The article considers the nature, occurrence mechanism and development of resonant vibrations found in the working stand equipment of cold rolling mills during the production of strips with a thickness of 0.4–0.6 mm at speeds of more than 12 m/s. Vibration causes are possibly based on changes in the metal properties during rolling due to acquired hardening and forming of internal friction peaks.
