In this paper, an inverse analysis technique is used to obtain the flow curve of materials in a hot rolling finishing mill. This technique is based on minimization of the differences between the experimental and computed values. The flow curves andMass flow control Using the mass flow principle, the outgoing strip thickness at the instant of rolling can be computed from the incoming strip thickness and the in- and out coming strip speeds. By means of this mass flow control concept, high control accuracy can be achieved. Therefore it en-hances clearly the concepts of thickness feedbackG. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 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. For the roughing mill reversible 4-high both roll force ...
