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.

“…After successful validation of a model, numerical simulation can be an efficient tool for relatively fast verification of the designed corrections in the production technology. Nowadays, by using numerical simulations, it is possible to predict the complete process, from the technology plan [7,8,9] through castings casting [10,11], including solidification [12][13][14], stress states [13][14][15][16][17], defects prediction [13,14,18,19] and resulting metallographic structure of a casting [19][20][21].…”

This paper describes the numerical modelling of solidification of ductile iron castings intended for the shipbuilding industry. Numerical simulations we performed in the computer software MAGMASOFT ® . The purpose of numerical simulations was to predict solidification under defined casting conditions to verify whether the proposed production technology is adequate. Attention was focused mainly on the porosity occurrence in the casting, which is determined at a stated location using an ultrasonic test. Variants with different types of chills were simulated to determine their effect on the size of porosity. The results of these variants are presented in this paper. The variant with the best results was then recommended for production under operating conditions.
