Numerical and experimental analysis of lubrication in strip cold rolling

Investigations 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...

Novel 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...
