3D Characterization of Continuously Cast Slabs

Abstract:

Article Preview

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.
