Application of experimental data for numerical simulation of cast iron solidification

Numerical analysis of cast iron solidification process is presented. The system casting – shell mould is discussed. The parameter controlling the solidification process called a substitute thermal capacity (STC) has been constructed in this way in order to take into account the evolution of latent heats connected with the solidification of austenite and eutectic phases. The information concerning the proper approximation of STC results from the experimental data using the thermal and derivative analysis (TDA).
