Draft in rolling is the difference between the initial thickness (ho) and final thickness (hf)min of the sheet metal.
The maximum possible draft (ΔH) in rolling is given by the equation,
(∆H)max = (ho)- (hf)min
(∆H)max = μ2R
Where, μ is coefficient of friction and, R is radius of roller
Therefore the maximum draft will depend upon the roll radius.Last updated on May 28, 2025
