Original abstract
The paper deals with two original mathematical models describing heat and mass transfer in CC-blank during its solidification and cooling down when passing through a CC-machine. That are the model of non-stationary temperature field and the model of chemical heterogeneity of CC slab. For interconnection of two models the mass transfer Fourier number has been determined on the basis of crystallization characterictics calculated in the model of chemical heterogeneity. The interconnection of models has been verified with the help of the original data obtained at temperature field and chemical heterogeneity research over the sectional area of CC-steel slab.
Czech abstract
Jsou popsány matematické modely vystihující přenos tepla a hmoty v kontinuálně lité bramě v průběhu tuhnutí a chladnutí při průchodu licím strojem. Jedná se o model nestacionárního teplotního pole a model chemické heterogenity. Pro propojení obou modelů je použito Fourierovo kriterium. Výsledky spojení obou modelů jsou verifikovány využitím originálních dat získaných při výzkumu teplotních polí a chemické heterogenity na průřezu odlévané bramy.
