Rolling processes 51 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 (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"diameter workrolls through 28:1 gears to .

An investigation of unsymmetrical deformation effects in hot strip rolling on singleroll drive mills is performed analytically. The model developed permits prediction of the rolling load, torque, and exit strip curvature as a function of mill geometry and strip reduction, through a formulation of the appropriate equilibrium equations and a realistic approximate yield criterion.
