the roll. In traditional English units, the total power can be expressed as Power (in hp) = 5.13 Where F is in pounds and L is in feet. Example: A 300-mm-wide strip 25-mm thick is fed through a rolling mill with two powered rolls each of radius = 250 mm. The work thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min.
