only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone. 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
