In the continuous casting secondary cooling process, heat is extracted from the slab surface by cooling water sprayed from arrays of nozzles. Efficient and uniform heat removal without cracking or deforming the slab is desired. The current study presents a numerical spray cooling model featuring the simulation of atomization and droplet impingement heat transfer during secondary cooling. Parametric studies are performed to investigate the effects of spray angle and the nozzle arrangements on heat transfer coefficient, and the relationship between casting speed and water flowrate. The simulation results provide insights into the optimization of secondary cooling practices under different conditions.
