Accurate heat transfer models of continuous casting require precise measurements to characterize boundary conditions, temperature and alloy-dependent thermal properties, optimization of numerical errors caused by model discretization, and validation with plant measurements. This study summarizes recent efforts of an international collaboration focused on modeling secondary cooling, conducting spray cooling measurements, analyzing the effect of material properties, and evaluating simulation results based on experimental and theoretical considerations. Laboratory measurements for spray cooling utilized a collector system to shape the spray water distribution, in addition to both transient and novel steady-state apparatus to obtain corresponding heat transfer coefficients. Results indicated that steady-state measurements produced significantly higher values compared to transient measurements. The ultimate goal of the research is to control spray conditions to optimize secondary cooling during continuous steel casting using both offline analysis tools and fully online models as software-sensors. Calibrated models will have the potential to predict, optimize, and manage temperature distribution effectively across all operating conditions.
