• Process control of vertical mills • Control of grinding feed and of classifier speed to achieve the required throughput • Improvement in mill stability • Consideration of process Considering the dynamic influence of the roll vibration on the lubricant film thickness in the rolling deformation area, nonlinear dynamic rolling forces related to film thickness in the Vertical–horizontal coupling nonlinear vibration characteristics of
Vertical Vibration Model for Unsteady Lubrication in RollsStrip
For frequently appeared selfexcited vibration phenomenon in highspeed rolling process on cold strip, this paper comprehensively uses rolling theory, lubrication In the process of high speed rolling, vertical vibration will cause the lubrication system in an unsteady state and may further cause the mill system oscillation instabilityVertical Vibration Model for Unsteady Lubrication in RollsStrip
Vertical Vibration Characteristics of Strip Rolling Mill under
Wang et al11)studied the rolling mill system dynamics of the unstable lubricating state of the gap between two rolls during the rolling mill operation And The results reveal the impact of system parameters upon the vertical nonlinear vibration of the cold rolling mill, which can serve as an academic reference for An advanced model of lubricated cold rolling with its
Control of mill vibration for unsteady lubrication based on metal
On the basis of rolling theory, hydromechanics theory, lubrication and friction theory, mechanic vibration theory, the vertical vibration model of rolling mill This paper presents the results of developing a vibration model for the rolling mill vertical system with respect to the roll gap under the unsteady lubrication Vertical–horizontal coupling nonlinear vibration characteristics of
