This paper deals with the characterization of solidification, cooling and expected
properties of continuously cast slabs. Semi-empirical models based on theoretical consideration and
on the results of heat transfer model are used for characterization of the following: surface and inner
temperature distribution of the cast semis, liquid sump depth and shape, liquid motion intensity
resulting in centerline segregation, parameters of the primary dendritic structure (primary and
secondary dendritic spacings, columnar to equiaxed transition position, CET). This method
provides an opportunity to make a realistic comparison between the solidification and final
properties of semis with different chemical compositions as a function of applied casting
technologies. The final goal of this research activity in the future is to define a comprehensive
quality function for optimizing continuous casting technology.
