AbstractIn cold rolling of thin strips i e foils Thickness 50 m it is important to take into accountthe flattening of the roll surfaces The displacement of the roll surface is obtained bycombining some results from the well known Hertzian theory of contact mechanics and roll modeling as a system of springs with different spring constants whithin contact conjuction Use of lubricants can reduce rolling force and improve surface properties of the foil Depending on the lubricant properties and rolling speed either hydrodynamic lubrication ormixed lubrication regimes can prevail The present theoretical work is focoused upon theinfluence of the rolling process parameters like rolling speed reduction ratio roll surfaceroughness and lubricant viscosity on the friction coefient and film thickness in the roll bite inthe mixed lubrication regim Results show that by viscosity increase rolling force decreaseand film thickness increase
