Original abstract
Corundo-baddeleyit material (CBM) – EUCOR – is a heat- and wear-resistant material even at extreme temperatures. This article introduces an original numerical model of solidification and cooling of this material in a non-metallic mold. The second, cooperating model of chemical heterogeneity and its application on EUCOR samples prove that the applied method of measuring the chemical heterogeneity provides the detailed quantitative information on the material structure and makes it possible to analyze the solidification process. The verification of both numerical models was conducted on a real cast 350 x 200 x 400 mm block.

Korundo-baddeleyitický material EUCOR je tepelně a otěruvzdorný materiál i při extrémních teplotách. Je předložen originální numerický model tuhnutí a chladnutí tohoto material v nekovové formě. Kooperující model chemické heterogeneity a jeho aplikace na vzorky z materiálu EUCOR dokazuje, že aplikovaná metoda měření chemické heterogeneity poskytuje detailní kvantitativní informace o structure material a umožňuje analyzovat process tuhnutí. Verifikace obou numerických modelů byla uskutečněna na odlitku 350x200x400 mm.
