Intelligent Combination of Basic Automation, Process Automation and Sensors Reduces Width Tolerances in Hot Rolling

Width tolerances in hot rolling are significantly reduced through an intelligent combination of basic automation, process automation and sensor integration. Roughing mill edger setups are calculated by combining physical models tuned by <br/>parameter optimization and on-line adaptation based on neural networks. Real-time sensor data of a radar-based width gauge used by fast control algorithms compensates in-bar variations and remaining residual setup deviations. Finishing mill width control includes spread modeling and feedforward and feedbackward control by tension. This approach minimizes width deviations, enhances product consistency, and supports digital transformation in steel production through predictive modeling and closed-loop control.
