Metal Rolling - Manufacturing Process
Roll materials are selected for strength, rigidity, and wear resistance. Roll materials vary dependent upon the specific metal rolling process. Common roll materials are cast iron, cast steel, and forged steel. Forged rolls are stronger and more rigid than cast rolls but are more difficult to manufacture.

Rolling (metalworking) - Wikipedia
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its ...

Basics of Rolling and Rolling Mills – IspatGuru
Basic concept of the rolling Rolling is a process used to shape metal into a thin long layer by passing it through a gap of two rollers rotating in different directions (clockwise and anti-clockwise). The gap between the two rollers is supposed to be smaller than the thickness of the work piece of the material to be formed.

The calender stack is a series of solid rolls, usually steel or cast iron, mounted horizontally and stacked vertically (Fig. 6.11).During machine calendering, the dry paper passes between the rolls under pressure, thereby improving the surface smoothness (for example, from imperfections caused by felt marks, cockle, lumps, fibrils, etc.) and gloss and making the caliper more …
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.

The Milling Process - UK Flour Millers
The flour milling process has evolved from wheat being ground between two large stone wheels (although this process does still occur in a few mills). In a roller mill the practice centres around separating the three components of a wheat seed – the white endosperm, the outer bran layers and the wheat germ.
