Original abstract

Solidification and cooling of a continuously cast steel and the simultaneous heating of the mould is, from the viewpoint of thermokinetics, a very complicated problem of transient heat and mass transfer.The solving of such a problem is impossible without a numerical model of the temperature field. An original 3D numerical model of the temperature field of a concasting had been used. The experimental research and data acquisition have to take place simultaneously with the numerical computation. In order to apply the secon original numerical model-a model of dendritic segregation of elements-it is necessary to analyze the heterogeneity of samples of the constituent elements and impurities in characteristic places of the solidifying slab.

Tuhnutí a chladnutí kontinuálně litých ocelových bram je velmi komplikovaný problém nestacionárního přenosu tepla a hmoty. Originální numerický 3D model teplotního pole umožňuje řešení tohoto problému. Aby bylo možné použít druhého numerického modelu – dendritické segregace prvků- je nezbytná analyza heterogenity vzorků konstitučních prvků a nečistot v charakteristických místech tuhnoucí bramy.
