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.

Jan 28, 2009· The rollers and the work-piece exert force on each other, and if either is absent, there is no force on either. The rollers exert force on the mill frame at their bearing points. There is no benefit to trying to make a distinction between who presses on who as it does not change what happens nor does it change the design of the rolling mill.
