A simplified approach to the simulation of direct reduction of iron ore

ILVA S.p.A., Genova Works, 16512 Genova, ItalyAbstract – This paper describes a model for the simulation of the process of direct re-duction of iron ore for steel production. The model is implemented through stand-alonesoftware and the simulation results have been compared with real experimental data. Thevery good agreement between the actual and simulated data proves that the model, de-spite its relative simplicity, takes into account all the fundamental phenomena of iron orereduction.Resume – Une approche simplifiee a la simulation de la reduction directe de mi-nerai de fer. Cet article decrit un modele pour la simulation du processus de reductiondirecte de minerai de fer pour la production d’acier. Le modele a ete mis en application parl’intermediaire d’un logiciel independant et les resultats de la simulation ont ete comparesa de veritables donnees experimentales. L’excellente concordance entre les donnees reelleset simulees montre que le modele, en depit de sa relative simplicite, prend en considerationtoutes les variables fondamentales de la reduction du minerai de fer.
