Numerical investigation and physical modeling for optimisation hydrodynamic processes in continuous casting tundish (original) (raw)

Metallurgical Research & Technology

Abstract

The article presents the results of comprehensive studies of hydrodynamic processes and features of single-strand tundish ladles, which can be used for continuous or semicontinuous casting of steel at small metallurgical plants. The results of physical and mathematical modelling of the movement of the melt flows in the tundish using various designs of metal receivers are shown in this article. In addition to this, the article shows how the presence of a stagnant zone between the metal receiver and the right narrow wall of the Tundish increases in time of metal flow into the dispenser zone by an average of 35–60%. It has been established that the position and height of the walls of the metal receiver relative to the axis of the incident jet are very significant for providing a rational picture of the movement of convective flows. When the height of the wall of the metal receiver (from the side of the dispenser) is reduced by 40–60 mm, the zones of increased turbulence may appear in t...
