Abstract

The residence time for individual tundish configuration is one of the most important factors of the tundish metallurgy. In the T-type tundishes, it is difficult to set a tundish furniture in order to obtain similar residence time for every strand. The tundish furniture is obviously designed for correct set ladle shroud position and angle. In this paper is quantified the ladle shroud deviation angle from vertical axis on residence time of three strand tundish of Železiarne Podbrezová, a.s. (ŽP). using water model in scale 1:2. In the continuous casting machine in ŽP, the manual ladle shroud mounting on ladle is used. Generally, the misalignment of the shroud has a negative effect on the flow of the steel in the tundish. This fact may negatively affect the cleanliness of the cast steel but also wearing of the exposed places of the tundish lining. The results are also evaluated by using sophisticated statistical methods.
