摘要
Strip mill vibration greatly affects the quality of products, rolling productivity, and even cause strip broken or equipment damage. In order to explore the serious vibration phenomena occured in CSP (Compact Strip Production) hot strip mill when rolling thin container strips, in this paper we established a mill main drive system nonlinear torsional vibration model, and emphatically studied the influence of rolling load, multi-stand coupling (tension) and interface friction on the torsional vibration of the system; Based on numerical simulation, field measurement and signal time-frequency analysis (Wigner-Ville distribution), we analyzed the mills torsional vibration and horizontal vibration characteristics, the influence of multi-stand coupling (tension) on the rolls torsional vibration.
