COOLING OF A MASSIVE CASTING OF DUCTILE CAST-IRON AND ITS NUMERICAL OPTIMIZATION

Popis výsledku v původním jazyce

An original application of ANSYS, based on the finite-element method, is applied for the numerical model of the temperature field of solidifying casting. The model simulated the forming of the temperature field of a two-ton 500x500x1000 mm casting from ductile cast-iron during the application of various methods of its cooling using steel chills. This model also provided results for the successive model of structural and chemical heterogeneity. The file containing the acquired results from both models, as well as from their organic unification, brings new and, simultaneously, remarkable findings of causal relationships between the structural and chemical heterogeneity. This has established a tool for the optimization of the structure with an even distribution of the spheroids of graphite in such a way so as to minimize the occurrence of degenerated shapes of graphite, which is one of the conditions for achieving good mechanical properties of castings of ductile cast-iron.
