In order to improve the automation degree of sintering production control, the uniformity of sintering process, and sintering production & specification, an automatic distribution system for sintering mixture is developed. A radar level gauge is used to monitor the material partition thickness value in the direction of the material surface width, and the target material thickness is compared to obtain a direct partition material thickness deviation. Then, the infrared thermography video and characteristic images of the tail section of the sintering machine are collected by infrared thermography technology, the temperature distribution of the sintering section in the width direction, the thickness of high-temperature zone, and the end point position of sintering are analyzed, while the material thickness deviation of indirect partition is obtained. Combined with the deviation of the material thickness of these two partitions, the speed of the sintered distribution roller and the opening of the small gate are adjusted by feedback, and the automatic distribution of sintering is realized under the condition with stable raw material structure. The production and application practice show that the radar level monitoring system and infrared thermography system can accurately detect the thickness of the material layer, identify the thermal state of the sintering section, and the automatic distribution system can run stably, which significantly reduces the intervention of the main control staff in the distribution process and has a positive effect on reducing the labor intensity of the operator.
