Abstract

A fast-computing model for crown and flatness in hot strip rolling and plate rolling has been developed based on steady-state elastic-plastic finite element simulations and an elastic buckling analysis. A single, geometry-independent tuning coefficient needs to be identified for each steel grade family. As a result, the model can be efficiently tuned to production mills. Implementation into the set-up environment “CID” of the SOLLAC Méditerranée hot strip mill is presented.
