Hot-rolled coils (HRCs) play a crucial role in diverse industries such as automotive, construction, and machinery. However, the cooling process of HRCs within storage yards often leads to nonuniform cooling due to complex thermal interactions between adjacent coils and variable environmental conditions, directly affecting the mechanical properties and overall steel quality. In this study, simplified heat transfer models based on the finite element method (FEM) were employed to generate realistic cooling scenario data. To address the computational limitations inherent in FEM, a novel management system integrating two artificial neural networks (ANNs) with deep and wide architectures, optimized through hyperparameter tuning, was developed. This system predicts temperature variations at multiple locations on coil surfaces in real-time, enabling strategic placements to minimize temperature disparities and enhance cooling uniformity. This real-time computational approach eliminates the need for additional cooling equipment while ensuring high-quality products. |
