Rolling processes 5-1 introduction Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working called hot rolling owing to the large amount of deformation required.
