The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
Sheet metal coil is often roll bent into thin walled pipe that is welded together, at its seam. The welding of the continuous product is incorporated into the rolling process. Roll forming of channels is a continuous alternative to a discrete channel bending process, such as the one illustrated in figure 269.

The method is highly useful in automatic control of camber. This type of control is easily adaptable in computer control of cold rolling mills. Rolling Practice V/S Anisotropy in Sheet Metal:
May 30, 2013· The rolling operation takes a solid piece of metal and breaks it down successively in several steps into different shapes such as flats, rounds, and sections etc. During rolling, metal is subjected to high compressive stresses as a result of the friction between the roll and the metal surface. Rolling has existed for hundreds of years.
