Effect Of Fluxing Agents On The Quality And Microstructure

Jun 01 2017 Indian iron ore fines with high alumina content 2.5 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 0.8 and pyroxenite fluxed pellets at varying MgO contents 0 to 3 to study their effect on the metallurgical properties.
