To obtain a better understanding of friction and contact mechanism in cold strip rolling, a refined asperity ploughing model and an asperity elastic deformation model have been developed. It is found that the asperity angles ��1 and ��2 significantly affect the tangential force and the coefficient of friction respectively. The theoretical prediction is in good agreement with the experimental results in Ref. [7]. The developed models can predict a reasonable frictional coefficient if it is applied to the cold rolling process. Copyright �� 2005 by ASME.
