    • Characterisation of an industrial Søderberg electrode 

      Glastonbury, Ralph Ivor (North-West University (South Africa), 2023)
      Søderberg electrode management (together with the initial design of the electrode system) is commonly considered as one of the most important aspects of profitable and safe submerged arc furnace operation, with some even ...
    • Coal-based reducing agents in ferroalloys and silicon production 

      Tangstad, Merete; Beukes, Johan Paul; Steenkamp, Joalet; Ringdalen, Eli (Elsevier, 2019)
      Manganese, chromium, and silicon ferroalloys are typical examples of alloys that are produced using carbon materials to remove oxygen from the raw materials. A majority of such alloys are currently produced in electric ...
    • Electrical resistivity of carbonaceous bed material at high temperature 

      Surup, Gerrit Ralf; Chaldien, Annah; Beukes, Johan Paul; Pedersen, Tommy Andre; Tangstad, Merete (Springer Verlag, 2020)
      This study reports the effect of high-temperature treatment on the electrical properties of charcoal, coal, and coke. The electrical resistivity of industrial charcoal samples used as a reducing agent in electric arc ...
