Nov 27, 2015·Understanding Rolling Process in LongProductRolling Mill... During thehot rollingof steel, heat is transferred to the rolls. If not cooled, the heat buildup causes increase in the temperature of the roll to a temperature equal to that of the stock being rolled. At this stage the roll would also undergo plastic deformation
