Description
Summary:A typical task from the range of thermal theory of foundry consists in the computation of solidification and cooling processes in the system casting-mould environment. From the technological point of view one can consider the following processes: • solidification of casting in moulding sand • solidification of casting in permanent mould • solidification of ingot in ingot mould • continuous casting process The physical features characterizing each of the above-mentioned technologies as well as a sort of casting material (pure metals, alloys, etc.) determine the adequate mathematical description of thermal processes, the admissible simplifications, the significance of certain technological parameters, etc. In this paper the applications of the BEM for numerical simulation of different foundry processes will be presented, in particular, the algorithms as a composition of the BEM for parabolic equations with certain procedures taking into account the course of solidification process will be discussed.
