SIFOU3D - A SOFTWARE TO BRING HELP IN TEC HNICAL CHOICES AND IN THE SUPERVISION OF FLAMES HEATING PROCESSES - ITS APPLICATION AT THE SOLLAC-FOS HOT STRIP MILL

The possibilities offered by a mathematical model, developed at Irsid to improve the control of the steel reheating furnaces at the hot stri p mills, are explained in this paper. The model allows to describe acc urately the heat transfers (in the fumes and in the slabs) and the fum es flow field in a reheating furnace. The main studies undertaken conc ern the effects of the burners on the thermal homogeneity of the slabs . The complementarity of the numerical simulations and the actions und ertaken at the Sollac fos plant are particularly shown.
