Rolling
???? The process of reducing the thickness or
changing the cross section of a long
workpiece by compressive forces applied
through a set of rolls

Strategies to reduce roll force
???? Reducing friction at the roll-workpiece interface
???? Using smaller diameter rolls to reduce the
contact area
???? Taking smaller reductions per pass to reduce
the contact area
???? Rolling at elevated temperatures to lower the
strength of the material
???? Applying front and/or back tensions to the strip
