Abstract
The lubrication characteristics during roll bite were evaluated by studying the friction coefficient, forward slip, rolling force and drive torque. Experiments were conducted on a laboratory rolling mill to assess the effects of these factors and the oil viscosity, surface roughness, reduction ratio and rolling speed on rolling behavior. Favorable lubrication conditions, indicated by a smaller forward slip and friction coefficient, were found when the reduction ratio or rolling speed was quite large. Cold rolling using a high viscosity lubricant is beneficial in reducing forward slip and friction coefficient. Increasing the isotropic surface roughness of the rolling strip can increase the friction coefficient and forward slip.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
