Abstract
Various kinds of base oils were applied to cold rolling aluminum strips on a test mill for evaluation of the influences of these base oils, aromatics contents and viscosity of base oils on their lubricating performances and surface reflectivity of rolled strips at annealing. Results showed that low friction coefficient and rolling force were obtained by using the normal paraffins, whereas their contaminations on the annealed strip surface were the same as those of other saturated hydrocarbons. Aromatics in base oil affected the surface reflectivity of annealed strips, but the decrease of aromatics in base oil was ineffective to improve rolled strips surface quality when it is less than 1%. Base oil viscosity has the great influences on the lubricating performances and surface reflectivity of annealed strips just in this condition.
