Hybrid model for improving width performances in hot strip mill

Abstract

A modelling strategy has been developed to reduce the overspread at the finisher of the HSM in Avilés. A new hybrid data based model elaborates the roughing and finishing mills set up. It has made it possible to reduce the overspread by 1.5 mm at the finisher since March 2005. The model is modular and flexible and it can be transferred to other installations
