Research on Direct Reduction Dynamic Model of Carbon-Bearing Pellet Containing Zinc

摘要：

gical Engineering, University of Science and Technology Beijing(USTB), Beijing 100083,China Base on reduction experimental data, considering the reduction process factors like carbon content, reductive removal of ZnO, changing size of pellet, and partial pressure of reducing gas, also coupled heat transfer, mass transfer and chemical reactions, a direct reduction mathematical model on carbonbearing pellet containing zinc has been established. The reliability of the model was testified by programming and experiments. Experiments showed that, under the reduction conditions that carbon and oxygen mole ratio at 1.0 and reduction temperature 1603K, metallization rate 87％ and dezincification rate 99％ were observed after 15 minutes of heating.
