The molten metal from tundish is directed to continuous casting mold by submerged entry nozzle (SEN). The SEN is usually bifurcated nozzle, which is made of different shape and angle. The melt flow structure in mold plays an important role. Thus, port of SEN is made at different angles to control the melt structure. Many authors have reported that longitudinal high magnitude of melt and subsequent production of turbulence causes severe defects in casted products. In the present work, the melt flow structure has been studied under different port angles. It has been seen that melt flow has been modified in the continuous casting mold. Moreover, it was found that the change in SEN port angle affects vertical downward velocity and turbulence behavior in the molten steel region.

“…The use of the new FCD under industrial conditions is preceded through simulation research of the continuous steel casting process. Numerical simulations that reflect the actual liquid steel flow in a tundish have been widely used [1,12,13]. The computer calculation results after applying a previously verified mathematical model allow us to get to know the full view of the metal movement hydrodynamic structure in the working volume of the tundish and ladle shroud.…”

Influence of ladle shroud and change in its position on liquid steel flow hydrodynamic structure in six-strand tundish Wpływ wylewu osłonowego kadzi stalowniczej i zmiany jego położenia na strukturę hydrodynamiczną przepływu ciekłej stali w sześciowylewowej kadzi pośredniej Abstract 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. StreszczenieW niniejszej pracy przedstawiono wyniki symulacji numerycznych przepływu ciekłej stali w sześciowylewowej kadzi pośredniej przeznaczonej do odlewania wlewków kwadratowych. Testowano wpływ zastosowania wylewu osłonowego i zmiany jego głębokości zanurzenia w ciekłej stali na zakres strefy przejściowej i kształtowanie udziałów przepływu ciekłej stali. Sprawdzono trzy głębokości zanurzenia wylewu osłonowego w ciekłej stali. Rezultaty obliczeń komputerowych wykazały, iż zastosowanie i zmiana położenia wylewu osłonowego wpływa lokalnie na kształt struktury hydrodynamicznej przepływu ciekłej stali w kadzi pośredniej. Symulacje numeryczne zrealizowano z wykorzystaniem programu komputerowego Ansys-Fluent. Słowa kluczowe: kadź pośrednia, ciągłe odlewanie stali, symulacja numeryczna, wylew osłonowy kadzi stalowniczej
