Abstract: Rolling tests of high purity aluminum foil were carried out at different speeds, surface morphology was observed with a three-dimensional non-contact surface profiler, and the effect of cold rolling speed on surface morphology of high purity aluminum foil was studied from the lubrication condition, autocovariance function of surface profile and power spectral density. The results show that the friction was mainly generated by the plastic deformation and plowing effect formed by the roll surface asperities pressing in the high purity aluminum surface in the rolling process. The surface roughness of aluminum foil mainly depended on the roll surface roughness, and the main feature of aluminum foil surface did not change with the variation of the rolling speed. When the rolling speed was increased from 5 m·s-1 to 7 m·s-1, there was no obvious changes on the transverse direction surface roughness of the aluminum foil, but the rolling direction surface roughness decreased, thus the surface morphology of aluminum foil was improved. The change of rolling speed had no effects on the autocorrelation of aliminum foil surface profile, and the aluminum foil surface profile was mainly the space random component with longer space wavelength.
