vertical side roll with bronze bearing for hot section mill 8

A coupled vibration model of hot rolling mill rolls under multiple nonlinear effects is established by considering the nonlinear spring force produced by the hydraulic cylinder the nonlinear friction between the work rolls the dynamic variation of rolling force and the effect of external excitation as well as according to the structural constraints of a fourhigh hot rolling mill in the [email protected]
