Laboratory-scale simulation tests, using RD commercial pellets and typical industrial operational parameters of a benchmarket RD shaft furnace, were conducted and planned using statistic and factorial analysis. In the simulated experiments, the following three regions of the DR shaft furnace were considered: Reduction, Transition and Cooling zones. Basically, three stages were considered in the research development: the step one, which analyzed the reactions and equations concerning pellet metallization and carbon precipitation; the step two, where the experiments focused essentially on the definition of the carburization kinetic equations occurring in the Transition and Cooling zones and, finally: the third step, which aimed to develop the “METCARB” computational progr am, conceived to simulate mathematically the metallization and carbon reactions along the height of the furnace. At last, an industrial case was presented in order to compare to the “METCARB” outputs.
