| Description
| - Department of Metallurgy, VSB – Technical University of Ostrava in Czech Republic and to explain especially the principle of tundish process simulations. The numerical modelling was realized by the CFD program FLUENT. There are possibilities to use a high number of settings in this professional modelling software. The paper describes the preprocessing, processing and post-processing phases of numerical modelling. The mesh of the tundish was designed by GAMBIT software. The boundary conditions were set according to experiment needs. The low-Reynolds k-epsilon model was used for final computation of steel flow. The post-processing data evaluation is also discussed. The physical simulation of tundish metallurgy processes utilizes a pair of conductivity and temperature probes situated in determined areas of the tundish model. The first pair is placed in the inlet area (shroud nozzle) and others are in the outlet zones (submersion nozzles). The probes response to the KCl concentration change after its injection into the water bath. Time delays between response at the inlet and individual outlets registration of concentration change are observed. Also, the RTD (Residence Time Distribution) curves are plotted based on the time dependency of concentration changes during experiments for individual outlets. There exist two basic methods of KCl concentration change utilization in this “water” physical tundish modelling methodology. The advantages and disadvantages of mentioned methods are discussed and possible future developments are outlined.
