Abstract

To analyze secondary cooling control systems in continuous steel slab casting, a mathematical heat-transfer model and corresponding software tool were developed. The model is based on nonlinear heat conduction and solidification equations to predict temperature distribution in a longitudinal cross-section. The user interface accepts casting parameters such as mold heat flow and water flow rates in each spray zone, while enabling real-time temperature monitoring through charts and graphs. Results comparing temperature distributions under open-loop (spray table) and model-based predictive control systems are presented. This user-friendly modeling software serves as an effective tool for steelmakers and researchers to optimize secondary cooling in offline numerical experiments, to observe and monitor the process in real time, or to develop control systems to better maintain temperature during transients, for enhanced slab quality.
