In order to solve the problem that it is difficult to accurately measure the moisture of sintering compound, particle size recognition technology and intelligent water distribution are combined, and an intelligent sintering water distribution system is developed. The system directly establishes the relationship between the adjustment of moisture and the size fraction of the compound, and adjusts the water addition in real time by establishing a supervised self-learning optimization control algorithm based on the particle size of the compound, so as to achieve the automatic closed-loop control of the moisture of sintering compound. In industrial practice data verification: After applying this intelligent water distribution system, the sintering utilization coefficient increases from 1.36 t/(m²·h) to 1.41 t/(m²·h), the sinter drum index increases from 78.10% to 78.64%, the negative sintering pressure decreases from 12.71 kPa to 12.14 kPa, and the main sintering pumping frequency decreases from 39.4 Hz to 38 Hz.
