9th International Conference on Modeling and Simulation of Metallurgical Processes in Steelmaking - STEELSIM2021

Numerical simulation plays a crucial role in the optimization of the ladle furnace. This work summarizes various works done to optimize flow modeling in the ladle furnace. This starts at the bubble scale with the development of a new measurement method based on machine learning. Then a comprehensive validation database was created on the physical modeling scale and the numerical model was optimized with it. Finally, this paper deals with the question of scaling the physical model scale to the industrial scale. For this purpose, different problems and their solutions are discussed and the flow of a full-scale 185 t ladle furnace calculated with the large eddy turbulence model is presented.
