    Abstract:

    In reaction models for gaseous reduction of iron ore agglomerates, the formations of both unreacted-core shrinking (UCS) model for one interface and UCS model for three interfaces and the developments of multi-stage zone-reaction models without and with considering solid-state diffusion are summarized; these models are used mainly for pellets but sometimes used for sinter. UCS model for six interfaces in consideration of quaternary calcium ferrite reduction process is newly developed for sinter. Comparisons of these reaction models for pellets and sinter are carried out by using experimental data on gaseous reduction of these iron ore agglomerates.
