Resumen
The structural integrity of shaped castings is closely related to their temperature-time evolution during solidification and the as-cast structure. A number of analytical and numerical models were developed in the last three decades to treat heat transfer during solidification, and the consequent simulation of freezing patterns in castings has provided many improvements in foundry processes. The use of casting solidification simulation could do much to increase the process knowledge. However, some uncertainties must be eliminated before such simulations can be widely accepted as realistic descriptions of processes such as: foundry, continuous casting of billets, blooms and slabs, strip casting, rapid solidification etc. The studies can be grouped in two categories: solidification in steady-state heat flow and in the unsteady-state regime. Reliable prediction in the latter category is of prime importance, since this class of heat flow regime encompasses the majority of industrial solidification processes. 60 550 698 701 Santos, C.A., Spim, J.A., Garcia, A., Mathematical modelling and optimization strategies (genetic algorithm and knowledge base) applied to the continuous casting of steel (2003) Engineering Applications of Artificial Intelligence, 16, pp. 511-527 Santos, C.A., Spim, J.A., Garcia, A., The use of artificial intelligence technique for the optimization of process parameters used in the continuous casting of steel (2002) Applied Mathematical Modeling, 26 (11), pp. 1077-1092 Spim, J.A., Garcia, A., Numerical analysis of solidification of complex shaped bodies: Coupling of mesh elements of different geometries (2000) Materials Science & Engineering A, 277, pp. 198-205 Spim, J.A., Garcia, A., A modified network approach for modelling solidification of complex shaped domains (2000) Numerical Heat Transfer Part B -Fundamentals, 38 (1), pp. 75-92
