What Is A Rolling Mill? 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 ...

Hot Rolling of Aluminium1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 Summary. Hot rolling is one of the most common and costeffective techniques to convert aluminium cast slab to flat sheet down to 2 mm thickness, which becomes the starting stock for cold rolling. Hot rolling is one of the most important manufacturing processes for flat rolled aluminium alloys as ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
