In order to know the effect of firing temperature on the properties of fluxed pellets, two firing temperatures of 1 225 ℃ and 1 255 ℃ were studied by 624 m² travelling grate machine. The results showed that with the increase of firing temperature from 1 225 ℃ to 1 255 ℃, the compressive strength of pellets increased from 2 504 N/P to 3 653 N/P, the 1h reduction degree decreased from 70% to 60.2%, the reduction swelling index decreased from 10.7% to 9.1%, the RDI_+6.3mm decreased from 79.7% to 60.5%, RDI_+3.15mm decreased from 90.8% to 84.9%, and RDI_-0.5mm changed little, the true density of pellets increased slightly, the apparent density increased significantly from 3.69 g/cm³ to 3.9 g/cm³, and the total porosity decreased from 23.2% to 18.86%. By adjusting the appropriate firing temperature and controlling the appropriate amount of liquid phase, it is conducive to the recrystallization of hematite and the uniform distribution of liquid phase, so as to improve the properties of fluxed pellets.
