N2 - Solidification models are an important tool for theprediction of temperatures and shell growth during the processof continuous casting of steel. To gain reliable simulationresults, it is crucial to use highly sophisticated materialdata and boundary conditions depending on different processparameters. The focus of this work lies on the utilizationof experimental data to describe the secondary coolingzone (SCZ) of a slab caster in the solidification model Tempsimu-3D. In this part of the caster, water and air-mist spraysare used to cool down the strand. To calculate the heattransfer coefficient caused by spray cooling (HTCspray), themodel uses a correlation between thewater impact density(WID) and the surface temperature of the slab. Togetherwith the heat removal due to roll contact and radiation, thisHTCspray is applied as a boundary condition for the SCZ.To adjust the parameters of the correlation formula, resultsfromWID and HTCmeasurements are used. For validation,the simulation results are compared with a measurementof the slab surface temperature.
