This paper is focused on the inherent characteristics of main drive system F5 cold-rolling mill in a steel plant. First, transmission mechanical structure was simplified to five-inertia torsional vibration model. Secondly, coupled model strip and roll established. The electromechanical coupling motor control rotor established again. Finally, AMESim software used calculate natural frequency unde...

research scientist, Quaker Chemical Corp., Uithoorn, The Netherlands [email protected] Cold rolling involves intensive frictional contact between two highly loaded metallic surfaces in sliding contact. Together with the deformation-related parameters, such as hardness and reduction, the frictional conditions in the roll bite determine the roll forces and torques required for rolling (Figu...

Controlling the tandem cold rolling of metal strip is a significant challenge to the control engineer. This is due mostly to complex interactions between the process variables, nonlinearities that change with process conditions, and long speed-dependent time delays. The present technology is limited in its capability for improvement in performance. This paper describes a new control strategy th...

To minimize the longitudinal strip thickness error in the hydraulic cold rolling industries and improve traditional AGC control scheme on this problem, we put forward a secure gauge control system based on Advanced RISC Machines (ARM) and intelligent PI control strategy. The traditional automatic gauge control (AGC) scheme depended on personal experience about the parameters. The new gauge cont...
