Rolling Process: Working, Application, Defects, Type of ...

The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming.

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 and to make the thickness uniform. 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 recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of u…

Types Of Rolling Process In Manufacturing Industry

13-08-2019· Rolling is the most important and widely used metal forming process because of its lower cost and higher productivity. The rolling process is best defined as the shaping of metals into semi-finished or finished forms by passing between rollers rotating in opposite direction. Just like any other metal forming process, rolling works in the same way.
