Abstract The horizontal vibration mechanism of hot tandem rolling mill was studied, and the relationship between the horizontal vibration and the rolling process parameters was obtained. Considering the gap between the bearing chock and the housing, the offset of work roll and backup roll, and the nonlinear damping, the nonlinear dynamic model of horizontal vibration of strip rolling mill was established, and the relationship model of horizontal vibration and rolling process parameters was also established. Then, the online horizontal vibration test was carried out on the F2 rolling mill of some steel plant. The test result shows that the horizontal vibration of the work roll is very strong, with an amplitude up to 4.5 g in the middle and later periods and more than 5 g at the end phase, and the main vibration frequencies are 40 Hz and 118 Hz. At the same time, based on the model established, the vibration simulation in the rolling process was made to investigate the effect of strip thickness, rolling speed and tensile stress on horizontal vibration. The simulation results show that: the acceleration amplitude of horizontal vibration is 4.8 g in the simulation, which agrees with the measured results, thus validating the model established. When the strip thickness is thinner, the influence on the horizontal vibration is larger; the influence of rolling speed on the horizontal vibration is strong, and the influence of tension on the horizontal vibration is small compared to other factors.
