If so, calculate the roll force, torque, and horsepower. Solution: The draft attempted in this rolling operation is d = 25 - 22 = 3mm From equation (5.6) we can find the maximum draft d max = (0.12) 2(250) = 3.6mm Since the maximum allowable draft exceeds the attempted reduction, the rolling operation is feasible. To compute rolling force, we need the contact length L and the average flow ...
