Abstract Scope |
For efficient operation of an electric arc furnace the tap-hole region is one of the most important parts. It experiences thermal stresses, creep and erosion. To consider these effects in a virtual design process it is necessary to use both sophisticated thermo-mechanical and fluid dynamics models.
In this article we demonstrate application of FEM, CFD and optimization methods to obtain tailored refractory linings.
We use linear elastic and creep models to perform numerical analyses of a geometrically simplified tap hole area. An experiment-based methodology to obtain Norton-Bailey creep parameters is presented. The significance of considering creep during the design process is demonstrated.
On the CFD side we perform a shape optimization of a tap hole channel. We minimize the flow resistance using an optimization method on a parameterized geometry of the tap hole channel. Using several geometric parameters, we minimize the resulting flow resistance. |
