This paper deals with the possibilities of using physical modelling to study the slag entrainment in the tundish. A levelof steel in the tundish is changing during sequential continuous casting. The most significant decrease in the steel leveloccurs when replacing ladles. It is generally known that if the height of steel level in the tundish drops below a certain criticallevel, it may generate vortexes over the nozzles and as a consequence entrainment of tundish slag into individual castingstrands can occur. Thus, it is necessary to identify the critical level of steel for specific operational conditions. In this paper,the development of physical modelling methodology is described as well as physical model corresponding to operationalcontinuous casting machine No. 2 in Třinecké železárny, a.s. The obtained results are discussed.
