Numerical Simulation of the Molten Steel Flow in the Tundish of CSC Machine / Symulacja Numeryczna Przepływu Ciekłej Stali W Kadzi Pośredniej Urządzenia COS

Abstract: The mathematical and numerical simulation model of the liquid steel flow in a tundish is presented in this paper. The problem was treated as a complex one. The velocity fields are obtained by solving the momentum equations and the continuity equation, whereas the thermal fields are calculated by solving the conduction equation with the convection term. One takes into consideration in the mathematical model the changes of thermophysical parameters depending on the temperature. The problem was solved by the fini… Show more

“…Temperature field during material melting and solidification is affected by the latent heat of fusion. Macro models describing solidification process for both pure metals [20][21][22][23] and alloys [24][25][26][27][28] can be found in the literature. Mostly, one domain approach is used with fuzzy solidification front in the model where latent heat is included into effective heat capacity.…”

“…During casting, the refractory lining of the tundish and the slag powders used guarantee the thermal stabilization needed for maintaining the casting temperature required for a given steel grade. Because of the liquid steel residing in the tundish for a specific duration (which is limited by the tundish capacity and the casting speed), it is essential to monitor the tundish operation by analyzing the hydrodynamic conditions [3][4][5]. The main and side liquid steel stream present in the tundish working space form a complex metal circulation pattern.…”

“…However, the efficiency of inclusion removal by simple flotation in the tundish is generally limited by the residence time of liquid metal as it flows through a tundish and the rise velocity of the buoyant particles. The rise velocity of a particle is a function of its size, smaller particles are harder to remove [6][7][8]. The flow pattern is also affected by the steel flow rate and its temperature distribution.…”

“…Empirical studies of the liquid metal flow in the tundish, due to the high temperatures and a lack of optical access, are almost impossible. For this reason, the numerical modelling is currently the main tool for analyzing the phenomena of continuous casting process [1][2][3][4][5][6][8][9][10]. In the present study, the numerical simulation was used.…”
