A Computational Fluid Dynamics Study on Physical Refining of Steel Melts by Filtration

• In this paper, a previous experimental investigation on physical refining of steel melts by filtration was numerically studied. To be specific, filtration of non-metallic alumina inclusions, in the size range of 1 to 100 [μm], from steel melt by using a square-celled monolithic alumina filter was simulated. Computational fluid dynamics (CFD) studies, including simulations of both fluid flow and particle tracing using one-way coupling method, were conducted. The CFD predicted results for particles in the size range  5 [μm] were compared to the published experimental data. The modelled filtration setup could capture 100 % of the particles larger than 50 [μm]. The percentage of the filtered particles decreases from 98% to 0% in the particle size range of 50 [μm] to 1[μm].
