COREX smelting reduction process which is freed of metallurgical coke provides a sustainable developing way for ironmaking industry. However, the shortage and high cost of pellets limit its development in China. Meanwhile, iron ore sinter has a great output in China. This work studied the reduction behaviors of sinter made from magnetite concentrates during the reducing process of COREX shaft furnace and compared the RI and RDI of sinter with BF process. The results showed that the reduction degree of sinter increased obviously during the temperature zone from 600℃ to 850℃, while the reduction degradation presented rapidly aggravate in the temperature zone from 450℃ to 550℃ in COREX shaft furnace. Sinter got higher RI than BF process but also got higher RDI in reduction temperature range from 450℃ to 600℃, which means sinter would have heavier disintegration in COREX shaft furnace.
