The stability of moisture of mixture is directly related to the granulation effect of sintering and heat transfer rate in sintering process so that the quality index of sinter is affected. It is found out that the main factors influencing stability of moisture of mixture include the moisture of iron charge, blending process as well as addition of fly ash and cold return fine through the comprehensive analysis on moisture of each crude fuel for 500 m2 sintering machine of Baotou Steel and factors influencing moisture of mixture. The stability of moisture of mixture is obviously improved and black pipes at sintering machine tail are reduced through producing process monitor and control of moisture of each iron charge, adjusting and optimizing production technologies as well as formulating corresponding measures such as production and operation methods and technical improvement of equipment so that such indexes as the qualified rate of alkalinity for finished sinter, stability of FeO, qualified rates of drum strength and average particle size are with year-on-year increase.
