Aluminum Rolling Process: Part One :: Total .

Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.

Fundamental concept of metal rolling

Fundamental concept of metal rolling 1) The arc of contact between the rolls and the metal is a part of a circle. 2) The coefficient of friction, µµµµ, is constant in theory, but in reality µµµµvaries along the arc of contact. 3) The metal is considered to deform plastically during rolling. 4) The volume of metal is constant before and after rolling. In practical the volume might ...
