The quality of steelwork products depends on the geometric precision of flat products. Heavyplate rolling mills produce plates for largediameter pipes and for use in shipbuilding, mechanical engineering, and construction. This is why the precision requirements are so stringent. Today's Mills 5000 produce flat products of up to 5 m in width; the operation of these units shows 'camber ...

Fig. 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.
