Description	An original three-dimensional model of solidification is used to describe the process of solidification and cooling of massive (500x1000x500) mm cast-iron sand moulds castings. The calculated mode of the kinetics of the temperature field of the casting was verified during casting with temperature measurements in selected points. The sizes and positions of the experimental samples are exactly defined and corresponding with the decreasing rate of solidification. The samples were metallographically analyzed. The following dependences have been determined according to experimental and calculated data: the average size of graphite spheroids and of graphite cells as well as the average distances among the particles of graphite – always as function of the local solidification time. It was found that the given characteristics are directly proportional to the logarithm of the local solidification time.
