AI Technical Summary

Technical Problem

Existing control methods for sintering waste heat circulation fans fail to accurately adapt to the complex dynamic parameter changes in the sintering process, resulting in low waste heat recovery efficiency, high energy consumption, and unstable equipment operation, making it difficult to balance waste heat recovery efficiency, sinter cooling effect, and quality.

Method used

A multi-source heterogeneous data integrated control and sensing system is adopted, which combines visual detection of sinter sensible heat and audio detection of air leakage in the cooler flue to construct a two-layer intelligent control model of feedforward adjustment and feedback correction, which quantifies key parameters in real time and dynamically adjusts the fan speed.
