and supply aluminum hot rolling mill facilities to foil rolling mills. This paper outlines the setting calculation systems we have provided to recent rolling mills.
In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. 2 Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel , into products such as structural steel I-beams , angle stock, channel stock , bar stock
the rolling of hot steel this is not a difficult problem and iron or steel rolls are suitable if more costly and must yield higher rolled tonnage. Carrying these calculations back to stand 6, using the Mill constant gives Roll and Motor RPM.

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. 2 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
