The multi-partner project new hot rolled deep drawing steel qualities consisted of a combination of theoretical, experimental work and a full-scale mill trial.

CRM has devised a theoretical model for the texture development and has done extensive laboratory hot rolling experiments.

HO has been concentrating on developing a theoretical friction model based on a more physical approach. The new model performs better than the classical method based on Coulomb's friction. However, it could not be validated satisfactorily due to insufficient and inaccurate experimental data.

RWTH-IEHK has examined the transformation and recrystallization kinetics of the IF-steel qualities specially devised for this project. Together with the information supplied by CRM, the exact combination of temperature and deformation (amount and rate) was established for the finishing hot rolling in a ferrite temperature regime.

British Steel was in charge of the characterization of the mechanical properties. Besides, they have done laboratory research on the effect of lubrication.

CSM has organized an extra mill trial to validate the computer simulations in preparation of the final mill trial.

This preliminary work resulted in a hypothesis for the processing of formable hot rolled strip. It soon became clear that this recipe could not be realized without sacrificing key elements like thickness or Lankford value due to the inevitable temperature constraints imposed by the layout of the cooling section of a conventional hot strip mill.
