9th ECCC European Continuous Casting Conference – ECCC 2017

A level of steel in the tundish is changing during sequential continuous casting. The most significant decrease of the steel level occurs when replacing ladles. It is generally known that if the height of steel level in the tundish drops below a certain critical level, it may generate vortexes over the nozzles and as a consequence entrainment of tundish slag into individual casting strands can occur. Thus, it is necessary to identify the critical level of steel for specific operational conditions. In this paper, the methodology of physical modelling is described. Physical modelling was focused on the evaluation of current conditions of steel casting at the application of different impact pads in the tundish. An influence of different casting speeds on critical bath level was also evaluated.
