摘要

As steel producers tackle the formation of multi-phase microstructures, which combine high strength levels with good cold formability, the need of mathematical models for the prediction of microstructural constituents has gained in importance, especially when new technologies such as Thin Slab and Strip Casting can be exploited to produce thin sheets. Off-line integrated models, combining thermo-mechanical and metallurgically-based sub-models, have been developed and validated in order to predict austenite evolution during hot rolling and controlled cooling of conventional and innovative processes for the production of strips. The flexibility and capability of the models in establishing suitable hot rolling and cooling strategies to manufacture advanced multi-phase steel coils are shown. The guidelines for the application of innovative routes based on near net shape processes and ultra fast cooling facilities to the production of dual phase and bainitic steels are discussed.
