Abstract
In order to investigate the effect of particle shape on the gaseous reduction rate of iron ore, iron oxide pellets of different shape were reduced with CO-CO₂ gas mixture. A reduction model for a non-spherical particle was proposed. Applicability of the proposed model was examined by comparing the analysis results from this model and one of the existing models for non-spherical particle. According to the result of applicability comparison, the fractional reduction calculated by the former model were on the better agreement of the observed ones than by the latter model. Investigation revealed that the assumption of the proposed model was reasonable and practicable.
