Numerical simulation of liquid flow and mixing steel in multi-strands tundish

Purpose: The aim of this study was estimation of working multi- strands tundish used in the domestic steel industry for the casting of medium size-products.Design/methodology/approach: Thus, actions were taken to determine the specific characteristics of the work object. There is practically no possibility to study metal movement on a real object, therefore the solution of this problem was to use modelling techniques. The numerical analysis based on mathematical model was chosen. The calculations were carried out in AnsysFluent.Findings: of research concerns for casting spatial velocity fields of temperature and intensity of steel turbulence. They were complemented by F and E types residence time distribution curves. Basing on these curves percentage participation of flows were calculated and kinetics of steel mixing in tundish was determined.Research limitations/implications: applying of commercial computational codes for analysis of work and units designing is rather a cheap tool. The optimal solution is to join numerical and physical modeling.Practical implications: presented results of research can be used for improving the hydrodynamic conditions occurring in industrial tundish.Originality/value: of this research is working out the characteristics of tundish working. The obtained results can improve considerably the effectiveness of CC process.
