Improved Drive Control for Multi-Stand Cold Rolling Mills
In multi-stand cold rolling mills an accurate synchronization of the mill drives is necessary for a good product quality and for a safe process operation. During the standard commissioning procedure the control performance of each drive is optimized individually. However, in normal operation mode the performance is then not always optimal due to the coupling of the drives by the strip being rol...
متن کاملControl of a Continuous Tandem Cold Metal Rolling Process
The continuous tandem cold rolling of metal strip is a highly nonlinear multi-variable complex process the control of which presents additional challenges over those encountered in the control of stand-alone tandem cold rolling. These challenges arise during the passage of the weld, which joins the head of the next strip to the tail of the present strip to maintain the continuity of rolling. Th...
متن کاملNovel Laboratory Lubrication Tests for Cold Rolling Emulsions
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...
متن کاملInvestigations on Cold Rolling of Strip in Attendance of Hydrodynamic Lubrication
In this paper an analytical model for cold rolling of strip has been described. This model is developed based on the slab method of analysis and the hydrodynamic lubrication. The characteristics of rolling are obtained from the equations of equilibrium and the plate was allowed to strain harden assuming that the lubricant behaves as a Newtonian fluid. The shear stress to the plate is obtained b...
