Analysing metal working processes. G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap.
