Abstract Scope |
Numerous electrochemical reactions were postulated for chemical elements such as S, O, Al, and Fe to describe metal refinement mechanisms in the ESR. Thus, understanding electrochemical transport of ions (by advection, diffusion, and electro-migration) within the slag bath and electrochemical (Faradaic) reactions at slag-metal-gas-mold interfaces are of great importance. We propose a model that includes the effect of transport/reaction of ions on the distribution of electric current density, and consequently the magnetohydrodynamics (MHD) within the slag bath as well as melt pool. The movement of slag-metal interface and mold current are also taken into account in our model. The former significantly impacts the electrical resistance/power signal, and consequently the melting behavior of the electrode during the process. The latter can affect the thickness of slag skin that in turn determines the surface quality of the final ingot. |
