The quality of steel slabs produced by continuous casting is influenced by various factors. Casting speed, cooling rates and the temperature distribution, particularly on the surface of casted product are factors with very strong impacts to the process and therefore, we focus on a determination of their optimal relationship. More precisely, this paper investigates how the optimal cooling depends on the chosen speed of casting. For finding this relationship we built our original 2D numerical model of the continuous casting process and by its optimization we acquire the cooling for producing the steel slabs with optimal quality. The numerical model is based on enthalpy approach, which can simulate phase and structural changes for steel of arbitrary chemical composition, and the cooling is included in boundary conditions in the form of heat transfer coefficients. The optimal heat transfer coefficients are obtained by a modern heuristic optimization algorithm, called Firefly algorithm. By repeated fixing of casting speed in the model to different values and finding its associated optimal cooling, we receive the investigated relationship. The future work is defining cooling rates as a function of heat transfer coefficients and surface temperature.
