An analytical 1D model for computing low-frequency electromagnetic fields in material layers: Application to metallurgical furnaces
Fromreide, Mads; Gómez, Dolores; Halvorsen, Svenn Anton; Salgado, Pilar (Journal article; Peer reviewed, 2025)An analytical one-dimensional model for the distribution of electric fields within multiple material layers is developed and analyzed. The model originates from the study of large three-phase electric smelting furnaces for ... -
Induced Currents in the Lining and Steel Shell of Submerged Arc Furnaces
Fromreide, Mads; Gómez, Dolores; Halvorsen, Svenn Anton; Salgado, Pilar (Peer reviewed; Journal article, 2023)Numerical models in 2D and 3D are used to study induced currents in the lining and steel shell of large three-phase submerged arc furnaces. The alternating currents supplied through the electrodes cause a significant amount ... -
Reduced 2D/1D mathematical models for analyzing inductive effects in submerged arc furnaces
Fromreide, Mads; Gomez, Dolores; Halvorsen, Svenn Anton; Herland, Egil Vålandsmyr; Salgado, Pilar (Peer reviewed; Journal article, 2021)Mathematical models have been developed to investigate the quantitative behaviour of the current and power distributions in large submerged arc furnaces, usually fed by a low-frequency alternating source. Reduced 2D and ...
