The reduction behavior of pellet was researched through the programming apparatus under simulated conditions of oxygen blast furnace(OBF)and traditional blast furnace(T-BF).The results indicated that compared with traditional blast furnace,the reduction starting temperature of pellet decreased by 60 ℃ under oxygen blast furnace condition.The reduction degree of pellet could almost reach 100% under oxygen blast furnace condition when the temperature reached 1 100 ℃,whereas it was only 82.49% in traditional blast furnace.The content of carbon in pellet of oxygen blast furnace was about 5times more than that of traditional blast furnace.In addition,the microstructure at the periphery and core of pellets after reaction was characterized by means of SEM and EDS.
