This paper presents a mixed lubrication model for cold rolling of metals. It conriders both hydrodynamic lubrication and asperity contact between the roll and the metal. The calculated results show the essential characteristics offriction and the pressure distribution in lhe roll bite, which indicate thal a constant coeficient of friction is a poor assumption. A weighting factor for the contribution of asperity contact is obtained, and the Hitchcock formula is found adequate for representing roll deformation in calculating the inlet lubricant j l m thickness.
