Published June 14, 2013 Practical Roll Techniques: Nip Crown

As an example let us assume that we have two 12-in. diameter rolls, and we find that the nip widths are 0.9-in. on the ends and 0.7-in. at the center under the loading at which we desire to run the rolls. Then by our formula, N 1= 0.7, N 2 = 0.9 and D = 12 and . Get price

Hot Rolled, Cold Rolled and Cold Drawn Steel

However, room temperature steel is less malleable than hot steel, so cold rolling cannot reduce the thickness of a work piece as much as hot rolling in a single pass. Commonly cold-rolled products often include similar hot rolled products like sheets and bars, but are usually smaller. Get price

Rolling [SubsTech]

2013/10/31A rolling mill is characterized by the maximum values of its roll separating force and the torque. The maximum amount of deformation (thickness reduction) which may be achieved in a single rolling pass is determined by the maximum roll separating force, maximum torque, work roll diameter, friction coefficient and mechanical strength of the rolled material and its width.

The basics of roll form tooling design

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.
