Numerical model of heterogeneity of the ductile cast-iron
Original language description
An original three-dimensional (3D) model of solidification is used to describe the process of solidification and cooling of massive 500x1000x500 mm ductile cast-iron castings. The castings are cast in sand moulds. The calculated mode of the kinetics of the temperature field of the casting is verified during casting with temperature measurements in selected points.The experimental samples - 15 mm in diameter and 12 mm high - are metallographically analysed and also in terms of heterogeneity of the chemical composition. Successively, the local solidification time (i.e. the time the specified position of the casting, remains within the temperature range between the liquidus and solidus) is also calculated using the 3D model. The following dependences arelater determined according to the experimental and calculated data: the average size of the graphite spheroids rg, graphite cells Rb and the average distances among the particles of graphite Lg - always as a function of the local solidifi
