SPARTA, M.  y  RISINGGARD, V.K.. A finite-element method model for a ferromanganese and silicomanganese pilot furnace. J. S. Afr. Inst. Min. Metall. [online]. 2024, vol.124, n.3, pp.85-92. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/2737/2024.

We report on the development of a finite-element method model for a pilot furnace for the production of manganese alloys. The model is a multiphysics model that addresses material flow, electrical conditions, heat transfer, and physical and chemical transformations. It is capable of studying both quasi-steady and transient states in time-dependent simulations. The model includes common charge materials and fluxes and can simulate production of both ferromanganese and silicomanganese alloys with acid and basic slags, as well as changing charge compositions. The model output provides access to the material distribution in the furnace during furnace runs, temperature profiles, current paths, energy balances, and alloy and slag production rates and compositions.
