The fabrication of high-strength steels is usually complex and results in a
sophisticated combination of properties. Full-size rolling mill experiments to test
different rolling strategies is costly due to mill downtime and potential damage
to the equipment. In this way, small-scale physical simulations have been shown
to be an effective method to replicate industrial rolling conditions. In the present
work, plate and strip rolling of C-Mn and microalloyed steels are simulated by
means of hot torsion and plane-strain compression tests. The effects of TMCP
variations will be evaluated in terms of MFS’s and final grain sizes. The results of
the present analysis also show that physical simulation can considerably reduce
steel development costs by minimizing plant trials. Physical simulation is also a
risk-free process and can lead to important process optimizations at negligible
costs as compared to mill trials. The present study is applicable to the
production of various steels such as pipeline, shipbuilding, structural and other
high-end grades.
