Summary: We consider the dynamic optimal cooling strategy for continuous casting under changing casting speed. We use as a simulation model the diffusion convection equation with phase transition. The finite element approximation of these equations is used. The cost function can have several objectives and constraints which are used as the penalty terms. A dynamic programming method is used for solving the finite dimensional optimal control problem. Numerical results are presented.
