In the present investigation an attempt has been made to determine the effect of firing temperture, firing time and ingredients/additives (CaO, MgO, SiO2, Al2O3) on the swelling behaviour of iron ore pellets. For this purpose two Indian iron ore fines from Bailadila and Noamundi deposits and chemically pure iron oxide were used.
From the results obtained, it is observed that the swelling of iron ore pellet is controlled by the firing temperature, firing time and additives/ingredients present in the pellet. The growth of iron whisker is controlled by these ingredients. The presence of free lime promotes the swelling index of the pellet.
