N2 - Solidification models are an important tool for theprediction of temperatures and shell growth during the processof continuous casting of steel.

In this part of the caster, water and air-mist spraysare used to cool down the strand.

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.
