Title:
STRIP STEEL PLATE CONVEXITY PREDICTION METHOD BASED ON DATA-DRIVING AND MECHANISM MODEL FUSION
Document Type and Number:
WIPO Patent Application WO/2023/130666
Kind Code:
A1
Abstract:
A strip steel plate convexity prediction method based on data-driving and mechanism model fusion, relating to the technical field of strip steel product quality control. By means of establishing a convexity mechanism model of a hot continuous rolling exit plate, the method combines the mechanism model with a DNN model to establish a strip steel convexity prediction DNN model; using a computed value of the mechanism model as a reference value of exit plate convexity, and taking the deviation amount between the reference value and the actual value of the exit plate convexity as an output of the strip steel convexity prediction DNN model, a sum of a predicted value of the strip steel convexity prediction DNN model and the reference value is then taken as a final predicted strip steel plate convexity value. The method uses the deviation between the computed value and the actual value as the output of the DNN model, which can reduce the range of prediction errors and guarantee more precise plate shape control. At the present stage, collection and storage aspects of industrial data of hot rolling production lines are well-developed. Therefore, the method has strong promotion capabilities, and provides a new method for improving the precision of strip steel plate exit plate convexity.
