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 Equation 1 calculates as shown in Equation 2

designed with respect to two aspects. The first is the wearing of a roll where high temperature decreases the durability of the surface layer. The second aspect is a thermal deformation of a roll. This is critical for the shape and tolerance of flat products. Cooling at rolling mill should be designed with consideration to
The cooling of work rolls is an important process in the hot rolling technology and cannot be taken as a marginal issue. The Heat Transfer and Fluid Flow Laboratory designs cooling of rolls to reach their long working life while rolled product is still well heat treated.
Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill sees instantaneously unless some damping system such as a surge hopper is used. Even though the feed rate averaged out over time may be within acceptable limits, the instant the surge hit the roll the feed rate
