A great number of research articles on the physical and mathematical modelling of tundish operation have been reported in the literature. Mazumdar and Guthrie1) summarized a large portion of these in a review article in ISIJ published in 1999. Because of the growing importance of tundish metallurgy and stringent demands regarding steel quality, a lot of further work has been done on tundish technology from1999 till date. This review summarizes the basics of physical modelling, mathematical modelling and the work of different researchers around the globe in the last decade ie 1999 to 2009. Current trends in research have been reviewed and critiqued.
