The hot direct charging of slabs and a lowering of the pusher-type furnace temperature make it possible to reduce the energy consumption when producing hot strip. But before such measures are realised in production there must be clarity concerning the accompanying metallurgical effects on the material properties. Within the framework of this research project, therefore, the influence of the above-mentioned measures on the properties of two deep-drawing grades, one micro-alloyed special deep-drawing grade (IF) and two micro-alloyed high-strength steels, was examined. To do this, cold, hot and direct charging, different hot-rolling conditions resulting from these charging variants, cold-rolling, and batch and continuous annealing were simulated in the laboratory. The hot deformation was performed with the aid of a continuous casting simulator of Thyssen Stahl AG and a hot deformation simulator of the Max Planck Institute for Ferrous Research in Düsseldorf.
