Abstract

The aim of the research was to analyze the influence of the flow behavior of liquid steel in a three-strand, asymmetric tundish when not all outlet openings are working. This problem was solved through physical modeling. The tests were carried out with the use of the water model of the continuous casting (CC) machine equipped with an asymmetrical, three-strand tundish model, made on a reducing scale. Modelling research concerned casting 110 x 110 mm square ingots. The obtained results of visualization tests and resistance time distribution (RTD) characteristics (F type) allowed to determine the method of mixing the steel (changes in mixing intensity were estimated) for the analyzed experimental variants.
