Jan 01, 2005 The new steering control 23 method is more stable, and strip steering has been improved by more than 50. Steering mm 1200 1000 5.CONCLUSION This paper described a newly-developed VSS control system for strip steering in hot rolling mills, which is based on sliding mode control using a steering observer.
The vertical vibration often occurs during the rolling production, which has an influence on the accuracy of rolling mill. In order to effectively suppress the vertical vibration of the rolling equipment, the rolling mill model with vibration absorber device was established. Based on the main resonance singularity of the rolling mill system, the best combination of opening parameters was obtained.

The unsteady lubrication is one of the major causes for self-excited vibration in rolling. But it is difficult to build a rolling chatter model which considers the unsteady lubrication state in roll bite. Using the regression exponential function model of rolling friction coefficient, a dynamic rolling process model was built. Coupling the dynamic rolling process model with a mill stand ...
