Abstract Scope |
The Ruhrstahl–Heraeus (RH) degasser, widely used in the production of ultra-low carbon steel, plays a crucial role in steel refining. Despite its widespread use, opportunities remain to optimize the internal flow characteristics. In the current study, a CFD based approach using a Volume of Fluid (VOF) and Discrete Phase Model (DPM) framework is developed to investigate the flow behavior in an industrial scale RH degasser.
The simulation results provide insights into the average circulation flowrate and velocity distributions across different locations inside the system, highlighting critical areas. Flow patterns within the vacuum chamber and the ladle are analyzed, and the circulation behavior in both regions is tracked over time. Additionally, the study evaluates the average diameter and the distribution of the lifting gas bubbles at various locations inside the snorkels and the vacuum chamber. |
