Theoretical Principles in Rolling a Metal | Industries | Metallurgy

In rolling, a metal is formed through a pair or revolving rolls with plain or grooved barrels. The metal changes its shape gradually during the period in which it is in contact with the two rolls. We will now try to study the basic theoretical principles in rolling a metal. Fig. 5.1 shows the rolling of a rectangular piece of [...]

Cold Rolling Process on Metals | Industries | Metallurgy

In this article we will discuss about the cold rolling process which is performed on metals. Sliding and Sticking in Rolling: At surface contact in rolling: (i) Very high local pressures and abnormal material flow occur at the nose and tail of the workpiece, (ii) The contact zone between the workpiece and the roll changes continuously, (iii) The direction of [...]
