Rolling Process in Metal Forming: A Brief Review

Abstract

The present study is about a brief review regarding rolling process. Metal forming process also known as solid state manufacturing process and rolling process is widely used conventional manufacturing method. In rolling technique, the raw metal passes between a rotating rolls which rotates in opposite direction resulting in reduction in thickness and change in cross section of the metal to achieve a desired shape. The permanent deformation of metal takes place due to compressive force applied by the rotating rollers on the work piece, the high compressive stress develops due to friction between the rollers and the surface of raw material. Length of contact between the rolls and workpiece is generally much smaller than the width of the sheet passing through it. The shape produced by rolling process may be plate, sheet, strip and sections such as rails, beams, channels, angles rods, bar etc
