AI Technical Summary
In the production of existing cold-rolled strips, the static model cannot be adjusted in real time, resulting in poor accuracy of plate shape control and affecting product quality stability.
The closed-loop control method of cold-rolled strip steel plate-shaped closed-loop control method based on dynamic feedback, by constructing a dynamic correlation matrix and graph attention network, the spatial correlation defect feature vector is extracted, the plate-shaped deviation signal is decomposed as a multi-modal component, a multi-dimensional defect feature vector is constructed, and the production control parameters are adjusted in combination with the defect classification model.
Accurate identification and timely adjustment of strip steel plate-shaped defects, improve the stability and control efficiency of plate-shaped quality, reduce invalid operation, and ensure product quality consistency.
