Abstract

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.
