Simulation analysis of liquid metal flow through an innovative reaction chamber (and its shape optimization) used in ductile iron production technology

Ductile iron castings are widely used in many industrial branches because of their mechanical properties. The production process of such a grade of cast iron requires the maintenance of the technological regime and the purity of initial charge material. For this reason, methods of manufacturing and controlling materials are constantly being developed. This publication presents a new method of modification and spheroidization in the mould. The innovation of this method is the use of specially developed construction of the reaction chamber. Simulation studies were conducted to analyze the flow profile of liquid metal in the developed shapes of the chamber. Subsequently, the changes in the geometry of the chamber were made and analyzed under the same boundary conditions. The result of the study is the designation of a structure that will provide the appropriate flow characteristics to achieve good quality castings.
