摘要：
To serve fundamental information for the operation of flue gas circulation sintering (FGCS) process, this study mainly focuses on the influence of the CO and CO2 content in the suction gas on the iron ore sintering process. The results indicated that the presence of a small amount of CO in suction gas was beneficial to improve the combustion efficiency of coke and the sintering productivity, yield and sinter strength. However, excessive of CO2 in suction gas worsen the combustion efficiency of coke and sintering indexes. The CO2 content in the suction gas should be less than 5 vol%.
