Calculation Force On Roller In Rolling Mills

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.
