Non-Linear Vibrations and Asymmetry in Coupled Tandem Hot Rolling Mills

This paper discusses the computer simulation of the interactions between the torsional vibration mode and linear vibration mode of a vertical edging mill and a horizontal roughing mill which are coupled by a hot steel slab. The influence of the mass, rigidity and damping of the slab in both elastic and plastic regions have been considered. This non-linear simulation also takes into account backlash on the drive shaft and asymmetrical rolling condition in horizontal mill.
