• Numerical calculations are presented describing the solidification of a thin wall ductile iron castings with a hypereutectic composition. Numerical model was implemented in Matlab–Simulink environment. The model takes into account the presence of off-eutectic austenite as well as primary graphite. Experimental verification was made using casting with the shape of Archimedes spiral. Thermal analysis showed that there is high temperature drop of liquid metal due to intensive heat transfer between the flowing metal stream—the mould material. Thermal analysis along with microstructure observations were made and show reasonable agreement of numerical calculations with experimental measurements.
