INFLUENCE OF LADLE SHROUD AND CHANGE IN ITS POSITION ON LIQUID STEEL FLOW HYDRODYNAMIC STRUCTURE IN SIX-STRAND TUNDISH

This paper presents the numerical simulation results of the liquid steel flow in a six-strand tundish used for casting billets. The influence of using a ladle shroud, changing its immersion depth in liquid steel on the transition zone, and shaping the liquid steel volume flow were tested. Three positions of the ladle shroud immersion depth in liquid steel were checked. The computer calculation results have shown that the use and position change of the ladle shroud locally influences the shape of the liquid steel hydrodynamic structure in the tundish. The numerical simulations were carried out using the Ansys-Fluent computer program.
