Mar 27, 2003· You can successfully roll-form a profile more than one way In fact, many roll form designers take different approaches to design and development Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.

The most common configuration is a single skin-pass mill that rolls in a single direction, with tension reels placed at both ends of the mill However other types are also used, such as a temper mill with two mill stands for higher tempering in tin-sheet production mills which include DCR (Double Cold Reduction) mills with two or even three.

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.
