| 英文摘要 |
| Flatness is an important indicator to measure the quality of quenched steel plate, and the prediction of flatness
is of great significance for the continuous and stable production of high-quality steel plate. This paper proposes a method
based on operating mode recognition to predict the flatness for the roller quenching process, which provides a reference
for the quenching production control decision. Firstly, the characteristics of the quenching process are analyzed. Then the
fuzzy C-means clustering algorithm is used to recognize the operating modes of the process, the support vector machine
is used to establish the flatness prediction model for each operating mode, and the improved particle swarm optimization
algorithm is applied to improve the accuracy of the model. Finally, experiments are performed using industrial production
data, and the results verify the feasibility and effectiveness of the flatness prediction method proposed in this paper. |
