Original Abstract

Izdelan je bil tri-dimenzionalni model strjevanja, ki opisuje proces strjrvanja in ohlajevanja masivnega železnega ulitka dimenzije 500x1000x500 mm v pesčene forme. Izračun kinetike temperaturnega polja ulitka je bil preverjen med ulivanjem z merjenjem temperatur na določenih točkah.Experimentalni vzorci so bili metalografsko preiskani glede na heterogenost kemijske sestave.

English abstract

An original three-dimensional model of solidification is used to describe the process of solidification and cooling of massive 550x1000x500 mm cast-iron castings in sand moulds. The calculating mode of the kinetics of the temperature field of the casting is verified during casting with temperature measurement in selected points. The experimental samples are metallographically analysed and also in terms of heterogenity of the chemical composition.

Key words in English

Three-dimensional model. Solidification. Cast-iron castings. Temperature field. Chemical heterogenity.
