See lessMaximum possible reduction is dependent on roll diameter and the coefficient of friction between rolls and the slab. Relation is ∇hmax = μ2R , so putting the values μ =0.2 and R=100 mm we will get ∇hmax = 4mm You can watch video of this solution as 15:40 https://www.youtube.com/watch?v=xpvU691n51QRead more
