Computer simulation has a significant application in the field of metallurgy. It is primarily an issue that deals with the issue of casting. The simulation of casting and solidification makes visible the foundry phenomena that take place in the gating system and the casting when the mold is filled with liquid metal and during its solidification.
The article deals with the design of the gating system and the simulation of the filling and solidification of a real casting made of ductile iron. In the next production process, this casting is thermally treated (isothermal hardening) and ADI cast iron is obtained. Ductile iron EN-GJS-700-2 is used in the foundry as the basic material for ADI cast iron.
The design of the gating system for a specific casting was designed in the CATIA V5R20 CAD system, and the computer simulation of casting and solidification was realized in the NovaFlow & Solid program. The correct design of the gating system is important mainly because of the resulting internal quality of the casting, the elimination of possible defects (shrinkages, micro shrinkages), as well as the increase in the use of liquid metal.
