Obiettivo
The production of high alloyed steel plates and sheets bears several problems of shape control during and after hot rolling. Many shape defects result from the behaviour of the solidification microstructure during hot rolling. This microstructure and the chemical segregation depend strongly on the solidification conditions. This leads to an anisotropy of the material at least during the first rolling passes, before re-crystallisation. The project aims at the control of the dimensions of flat products, the generation of savings in metal, energy and processing costs and the increase of the homogeneity of the delivered products. The research will look for an accurate understanding of the relationship between the chemical composition of the material and its initial microstructure in the as-solidified state as well as the microstructure and the shape after hot rolling.
