Abstract

Increasing the demand for cold rolled ultra thin strip as feedstock for miniaturized
products has encouraged researchers to investigate the ways to increase the quality of such
products, especially those related to strip surface roughness. Surface is known as quality factor in
most of manufacturing processes. In this paper, the effect of the rolling parameters on the surface
roughness transformation during metal rolling has been studied. The experimental results
demonstrate that the surface roughness transformation during metal rolling is highly affected by the
designation of the processing parameters such as finishing temperature, reduction, rolling passes
and lubrication. The results have been discussed to verify the validity of the new findings.
