Metallurgy and flow control in the tundish Session 2 1 NUMERICAL MODELING OF NON- improvement in NMI removal from liquid steel, both in the tundish and in the mould of a CSC machine. For METALLIC INCLUSIONS BAHAVIOUR the tundish, a number of very interesting methods IN THE ONE STRAND TUNDISH have been developed to stimulate steel refining intensity [3-6]. Considering the fact that liquid steel Adam Cwudziński, Jan Jowsa stays in the tundish for a considerable length of time, Czestochowa University of Technology, Faculty of this time could be used for taking NMI out from the Materials Processing Technology and Applied liquid steel into the tundish powder. It is known that Physics, Department of Metals Extraction and the longer time of steel residence in the tundish, the Recirculation, Armii Krajowej 19 ave, 42-200 greater opportunities are for enhancing the steel Czestochowa, Poland, e-mail: purity degree. The tundish steel residence time can cwudzinski@wip.pcz.pl be extended by incorporating steel flow control devices into the tundish working space. It is more The article presents the results of computer
