An innovative process for direct reduction of cold bound Binder Behavior on Chromite Carbon Composite Pellets

Successfully developed an innovative process of direct reduction of cold bound pellets from iron ore concentrate with a coal based rotary kiln in comparison with the traditional direct reduction of fired oxide pellets in coal based rotary kilns possesses such advantages as shorter flowsheetphenomenon is critical for iron ore pellets because the strength decreases in the temperature range of 973 K For the carbothermic reduction of chromite the reduction starts at temperatures higher than K which is an advantage because the process avoids additional degradation and at this temperature the strength is enhanced by the sintering process The objective of this work is
