Tracks: EAF Raw Materials & DRI, Use of DRI in Steelmaking

The use of DRI as metallic charge in any EAF entails countless challenges for steelmakers, one of them being to avoid or minimize refractory wear caused by the oxides contained in the gangue. The best way to address this problem is by predicting through a mass balance model the evolution of slag composition as the heat is processed, in order to define the right amount of MgO and CaO to be fed and the proper opportunity for doing it. The ultimate goal is to have a slag compatible with the EAF refractories and the best foaming properties at the lowest possible cost.
