The behavior of CO during sintering ignition and sintering process was analyzed,the cur-rent status of the CO control during sintering process was overviewed.The sintering flue gas circula-tion,material surface steam injection,oxygen-enriched ignition and the CO control during sintering process were mainly discussed.It is pointed out that for the selection of the circulating position of the flue gas on the material surface,when the humidity of circulating mixed flue gas is greater than 8%and the temperature and oxygen content are low,the sintering machine tail is selected,when the mois-ture content is 6.0%～8.0%,the temperature and oxygen content is high,select the front of sintering machine.The optimization of sintering raw material and fuel batching structure,and the optimization on process parameters of oxygen-enriched ignition and material surface steam injection need to be fur-ther investigated,so as to reduce CO emissions under the premise of ensuring the quality of sinter and achieve the purpose of energy saving and emission reduction.
