Rolling (metalworking) | Article about Rolling hot forged mill rolls for rolling 60 degree angle steel

When a very smooth surface is not required, the surface roughness is added to the rolls in order to increase the angle of bite and, thus, of draft. In practice, the angles of bite are 20°-26° in hot rolling with smooth rolls, 27°34° in hot rolling with notched surfaces, and 2°6° in cold rolling with a lubricant.Rolling Process: Types, Working, Terminology and ApplicationMay 01, 2017 · Rolling works on same as any other metal forming process.

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.
