Rolling Process Working Application Defects

The rolling process is a metal forming process in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness This process is mainly focused on the cross section of the ingot or the metal which is forming Mainly by this process we reduce the thickness of the metal workpiece Now the rolling processes are mainly
