Besides “normal rolling conditions” a stable, theoretical assumption mills experience many different changes in rolling conditions. After a roll change or a mill stop rolls need some time to return to stable

Fundamental concept of metal rolling mtixtl

2016-4-25  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
