The Influence of Friction Coefficient on Forward Slip in Experimental Research on Cold Longitudinal Flat Rolling

The Influence of Friction Coefficient on Forward Slip in Experimental Research on Cold Longitudinal Flat Rolling

MIŁEK Tomasz

Abstract. The paper presents experimental results that concern cold longitudinal rolling of flat bars made from EN AW-6063 aluminium for different conditions. The investigations aimed at determining the impact of friction factors on the forward slip. The friction factors were determined by the method of the roll bite angle. The forward slips were calculated from Fink’s, Drezden’s and Vinogradov’s formulae. On the basis of investigations of cold longitudinal rolling of flat bars made from EN AW-6063 aluminium, it was found that the forward slip increases with an increase in friction factor.
