Model Order Reduction for Boundary Condition Estimation in Casting Machinery

In continuous casting machinery, the molten metal solidifies in a mold. In order to control the casting process, a proper knowledge of the heat flux between the mold and the metal is crucial. This boundary condition can be estimated using thermocouples measurements inside the mold and solving an inverse problem. In this paper, we describe the application of model order reduction techniques to this problem that allow its solution in real time.
