A study on the preferred physico-chemical and metallurgical properties of MgO based pellets have been undertaken under high PCR BF operation condition, assuming higher pellet ratio in a ferrous burden in order to secure a higher productivity of sinter plants. Various experimental condition simulating a high PCR operation were aimed at evaluating commercial pellets under a high production rate operation. Higher burden weight resulted in a lowering of the softening temperature, whereas an increase of hydrogen content in the reducing gas raised the softening temperature. As a result of various changes inside the furnace with increased PCR, the size-consist of all charge materials must be controlled and maintained aside from monitoring metallurgical properties of them.
