Forward slip during the rolling process is adopted as a measure in evaluating rolling stability. Forward slip during cold rolling of aluminum has a serious effect on the productivity as well as the quality of rolled sheets. The forward slip must remain within a specified range depending on the thickness of sheet if the rolling is to stay stable. Rolling speed, rolling tension, rolling oil viscosity, additives, rolling surface roughness, and roll diameter constitute an important factor for controlling forward slip during rolling. The present paper examines the effects of these factors on forward slip using both production-type and experimental rolling mills.
