    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.

    6. Rolling. A 300-mm-wide strip with 25 mm thickness is fed through a rolling mill with two powered rolls each of radius 250mm. The workpiece thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min. The workpiece has a flow curve defined by K-275MPa, and n-0.15, and work/roll friction coefficient is 0.12.
