Kinetic mechanism of FeCr2O4 reduction in carbon-containing iron melt

Direct alloying of chromium by chromite attracts a lot interest for its superiority in energy-saving and process simplification. The knowledge reduction FeCr2O4, the main component chromite, is key to understanding mechanism from chromite. effect melt composition (carbon addition) temperature on FeCr2O4 carbon-containing iron was studied. higher carbon content melt, recovery obtained. Similarly, favourable FeCr2O4. impeded addition due lower activity resulting strong attraction between chromium. kinetics dissolving were investigated, results indicated that controlling step chemical reaction at FeCr2O4/melt interface 1823K. And calculated activation energy 392.82 kJ/mol.
