This article is dedicated to the study of the influence of esters and acids content on anti-friction properties of rolling oil used in the hot rolling of aluminum and aluminum alloys. The coefficient of friction was obtained as a result of experiments using alloy 3104 stock ultimate reduction method. This method enables test performance under conditions much similar to production ones than those of a four-high machine test. To create normal contact stress distribution curve in the deformation zone, theoretical computation was made using Deform 2 D software. Practical experiments were carried out on a laboratory four-high rolling mill for rolling sheets and strips, that allowed to establish a link between coefficient of friction value and the content of esters and fatty acids in the rolling oil.
Keywords: friction coefficient, rolling lubrication, bite angle, breakdown rate reduction practice, aluminum alloys.
