Abstract

Two hydrodynamic problems related to the wear suffered by refractory linings at blast furnace runners during a stage of the steelmaking process are proposed. A thermo-hydrodynamic model is posed with the scope of finding the position of the critical isotherms inside the solid refractory layers. The computational domain is based on a runner at the ArcelorMittal Company, where the three-phase flow of slag, hot metal and air is solved using the SST K − ω turbulence model and the VOF method. Radiation heat transfer is accounted for using the S2S model. The impact of a jet of hot metal falling from the blast furnace on the runner is also analyzed using a similar hydrodynamic model. Shear stress, which is the main driving factor of the erosion rate, is computed at the impinging zone. Both models are solved using ANSYS Fluent.
