WhatsApp: +86 18838072829Fig. shows a threedimensional representation of a rolling process, and Fig. shows its schematic representation. The presence of friction between the workpiece and the counterrotating rolls drags the workpiece into the roll gap. As the roll gap is smaller than the input thickness of the workpiece, a product with less thickness, compared to the input thickness, is achieved.
