The stability of blast furnace process depends upon the quality of raw materials charged into the furnace. Among iron-bearing materials, pellets are an important feed material for the blast furnace operation. However, pellets exhibit swelling inside the blast furnace due to the high temperature inside the furnace, which causes dissociation of pellets and if swelling index is not controlled properly, it gets crumbled into fragments. This results in the deterioration of the gas permeability due to the void blockage. Therefore, it is important to characterize pellets prior to its utilisation in the blast furnace. In the present study, the effect of increase in basicity on the physicochemical properties of pellets is investigated and an attempt is made to derive an optimum pellet basicity for desired properties in the blast furnace operation.
