Solidification models are an important tool for the
prediction of temperatures and shell growth during the process
of continuous casting of steel. To gain reliable simulation
results, it is crucial to use highly sophisticated material
data and boundary conditions depending on different process
parameters. The focus of this work lies on the utilization
of experimental data to describe the secondary cooling
zone (SCZ) of a slab caster in the solidification model Tempsimu-
3D. In this part of the caster, water and air-mist sprays
are used to cool down the strand. To calculate the heat
transfer coefficient caused by spray cooling (HTCspray), the
model uses a correlation between thewater impact density
(WID) and the surface temperature of the slab. Together
with the heat removal due to roll contact and radiation, this
HTCspray is applied as a boundary condition for the SCZ.
To adjust the parameters of the correlation formula, results
fromWID and HTCmeasurements are used. For validation,
the simulation results are compared with a measurement
of the slab surface temperature.
