“…This approach eliminates the impact of deviations between steel strip speed and actual speed on temperature control accuracy in the after-rolling cooling control system by continuously updating the speed of steel strip samples in the model and recalculating sample temperatures in real-time. Dong Chen et al [8] proposed a temperature distribution prediction method based on recursive neural networks to address the challenge of rapidly adjusting temperature and water distribution in the cooling section during variable-speed rolling.…”

“…Compared to traditional laminar cooling systems, ultra-fast cooling can effectively break the air film on the surface of steel strip, achieving highly efficient, uniform, and precise cooling for plate and strip of hot rolling. Ultra-fast cooling has become a trend in the development of post-rolling cooling control technology for hot-rolled plate strip steel both domestically and internationally [2][3][4]. The post-rolling cooling control system for plate and strip of hot rolling has the disadvantages of hysteresis, nonlinearity, and complexity.…”

“…When the cooling process is changed, the residual stress in the hot-rolled strip is bound to change as well. Previous researchers have optimized the cooling process of hot-rolled strip mainly from the microstructure of the product, ignoring the effect of the cooling process on the residual stress [10,11]. Multi-objective optimization of the cooling process of hot-rolled strip, taking into account the microstructure and residual stress, is extremely important for improving the overall quality of the product.…”
