Abstract

The article deals with numerical simulations of filling and solidification of ductile iron castings produced in the MOTOR JIKOV Slévárna (Foundry). The simulations we performed in the ProCAST simulation software. The research analyses the geometry of the gating system consisting of two Branches, with a total of 12 castings type “YOKE A”. Each of the Branches contained a different gate shape. The operational partner defined operating conditions. Based on it, casting, solidification and stress states were calculated. An analysis of selected parameters was then performed to verify the influence of individual shapes of gates on the filling and solidification. Some differences in filling and solidification between the individual Branches were found. However, these differences are not significant. The findings are discussed in the text of this paper.
