Numerical analysis of cast iron solidification process

In the paper a certain algorithm of solidification process numerical modelling is presented. In particular, the iron casting solidifying in typical moulding sand is considered. Proposed numerical model allows to take into account the specific features of cast iron solidification (the process proceeds partially in an interval of temperature and partially in a constant temperature). The system casting-mold environment is analyzed and the adequate numerical algorithm constitutes a composition of the Finite Element Method (casting) and 2nd scheme of the Boundary Element Method (mold). The practical aims of worked out numerical model are connected with the chill tendency estimation.
