• 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 ...
    • Bulk Resistivity of Materials in the Si/FeSi Furnace 

      Hoover, Haley Iris; Fromreide, Mads; Sævarsdottir, Gudrun Arnbjörg; Tangstad, Merete (Journal article, 2023)
      The formation of silicon carbide (SiC) and the energy distribution in the furnace are two important parameters in evaluating furnace operations. The energy distribution is determined by the resistivity of the materials in ...
    • Electrical conditions in 3-phase submerged arc furnaces: learning from the ElMet project 

      Halvorsen, Svenn Anton; Sparta, Manuel; Risinggård, Vetle Kjær; Fromreide, Mads (Journal article, 2021)
      ElMet is the short name for a competence project (2015-2020) on electrical conditions in 3-phase submerged arc furnaces (SAFs). In the project, NORCE has cooperated closely with The Norwegian University of Science and ...

      Meland, Kjersti V.; Kleinegris, Dorinde Mechtilde Meike; Enerstvedt, Anna Kraaijeveld; Fromreide, Mads (Research report, 2023)
      Denne forstudien har undersøkt potensialet for utvikling av nye vekstnæringer ved å tilrettelegge for sirkulært og bioøkonomisk samarbeid i Sauda og Suldal. Forstudien har kartlagt ressurs- og sidestrømmer til en gruppe ...
    • 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 ...
    • Predicting Motion Patterns Using Optimal Paths 

      Fromreide, Mads; Hansen, Alex (Peer reviewed; Journal article, 2021)
      The ability to navigate safely and efficiently through a given landscape is relevant for any intelligent moving object. Examples range from robotic science and traffic analysis, to the behavior within an ecosystem. Many ...
    • 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 ...
