A mathematical model has been developed that predict the final mechanical properties of hot rolled steels. It consists of submodels for static and metadynamic recrystallisation, grain growth and the transformed ferrite grain size. Each submodel was characterised for a wide range of C-Mn and HSLA steels. The total microstructure model has been integrated into process models and evaluated using production data for plate, structural, bar and strip rolling. Results to date indicate that the accuracy of the model is excellent and is suitable for the evaluation of new steel grades and the development of optimised thermomechanical processing routes.
