Study on Reduction Kinetics of Iron Ore Sinter Using Coke Dust

Sintering is the most important process where iron o re fines are converted into a suitable lumpy product for blast furnace consumption. In this study, received sinter from Vizag Steel Plant, India has been used. The solid state isothermal reduction kinetics has been carried out sing coke dust (treated as industrial waste) as re ductant at temperature 1373K over a period of time from 5 to 90 minutes. The chemical analyses have been performed to get the degree of metallization of the reduced sinters and these data are used as input for the determination f the best fitted kinetic model. The characterizations of the reduced sinters are analyzed by XRD. The reduction mechanism found to be contracting geometry.
