  • Effect of basicity on the reduction swelling behavior and

    Limestone fluxed iron ore pellets are reduced in COrich atmosphere generally accompanied by swelling behavior If the reduction swelling index (RSI) exceeds the normal range (≥20%), it will seriously hinder the stable and anterograde production of iron makingIn traditional fluxed pellets, the flux is added as limestone (CaCO 3) or dolomite (CaMg(CO 3) 2), neither of which has any appreciable binding properties However, if either of these flux components is calcined to either CaO or CaMgO 2 and then hydrated and added to the pellets, they can be quite effective bindersPelletization an overview | ScienceDirect Topicswere produced in a laboratoryscale pelletizing drum and fired in sample baskets set in the middle of the sintering belt on the same production line as commercial blast furnace pellets One set of pellets was fluxed slightly with limestone (CaCO 3) and was labelled “nonfluxed”, while the other one was highly limestonefluxed and wasInternational Journal of Mineral Processing

  • Influence of flux additives on iron ore oxidized pellets

    fluxed pellets were evaluated in Refs[10−13], and suitable basicity and MgO content were also assured Conclusions were established that limestone, dolomite, magnesia and so on could be used to make a fluxed pellet that had superior metallurgical propertiesHowever, induration at 1280°C for 10 minutes also shows good CCS for both pellets such as 260 kg/pellet for limestone fluxed pellet and 290 kg/pellet for calcined lime fluxed pellet Further, Fig 14 depicts that indurated pellet with calcined lime at both 1280°C and 1300°C showed higher CCS than limestone plus bentonite added pelletsDevelopment on Iron Ore Pelletization Using CalcinedIndian iron ore fines with high alumina content (~25% Al 2 O 3 ) resulted in poor quality pellets and a study was under taken to establish suitable pellet chemistry through proper fluxing agents Limestone fluxed pellets were prepared at varying basicity (0 to 08) and pyroxenite fluxed pellets at varying MgO contents (0 to 3%) to study their effect on the metallurgical propertiesEffect of Fluxing Agents on the Quality and Microstructure
