Secondary cooling is a critical step in achieving the desired surface quality of steel
grades in continuous casting. The quality of the surface is highly dependent on the
heat transfer coefficients (HTC) between the air-mist cooling sprays and the strand
surface. The laboratory setups characterizing the HTC have been numerous, but the
recently developed nozzle measuring stand (NMS) at “Montanuniversitaet Leoben”
is unique in its ability to measure water distribution, impact pressure, and local HTC
for a wide range of spray parameters, including the overlap region between two
sprays. By embedding the NMS into the m²CAST 2D-FV-solidification simulation
software, the measured parameters can be transformed via various regression
models to enable direct control of surface temperature during CC.
