    • Airborne Emissions from Mn Ferroalloy Production 

      Kero, Ida; Eidem, Per Anders; Ma, Yan; Indresand, Hege; Aarhaug, Thor Anders; Grådahl, Svend (Journal article; Peer reviewed, 2018)
      Airborne emissions from metal production represent a health, safety, and environmental challenge to which more and more attention is being directed. Industries worldwide, as well as authorities and others, are resolute in ...

    • Carbon Cathode Wear in Aluminium Electrolysis Cells 

      Senanu, Samuel; Wang, Zhaohui; Ratvik, Arne Petter; Grande, Tor (Peer reviewed; Journal article, 2019)
      Autopsies of six spent potlinings with different carbon cathode block grades, amperage regimes and cell designs were conducted at three separate smelters to reveal possible mechanisms causing cathode wear. The microstructure ...

    • Evaluation of Filtration Efficiency of Ceramic Foam Filters (CFF) Using a Hydraulic Water System 

      Hassanabadi, Massoud; Akhtar, Shahid; Bilek, Petr; Aune, Ragnhild E. (Journal article; Peer reviewed, 2018)
      The filtration efficiency of Ceramic Foam Filters (CFFs) of grades 50 and 65 has been quantitatively evaluated using a hydraulic water system. Distilled water seeded with Polystyrene Microsphere particles with a distribution ...

    • Grain Refinement of Commercial EC Grade 1370 Aluminium Alloy for Electrical Applications 

      Hassanabadi, Massoud; Akhtar, Shahid; Arnberg, Lars; Aune, Ragnhild E. (Journal article; Peer reviewed, 2018)
      The purpose of the present study was to investigate the effect of different grain refiners’ additions on structure and electrical conductivity of commercially electrically conductive (EC) grade 1370 aluminium alloy. A ...

    • Pilot Scale Production of Manganese Ferroalloys Using Heat-Treated Mn-Nodules 

      Tangstad, Merete; Ringdalen, Eli; Manilla, Edmundo; Davila, Daniel (Journal article; Peer reviewed, 2017)
      Pilot-scale experiments are one way to investigate the process patterns and the reaction mechanisms of processes and raw materials. To understand a process fully, both theoretical considerations as well as small-scale ...

    • The Kinetics of Boron Transfer in Slag Refining of Silicon 

      Krystad, Egil; Tang, Kai; Tranell, Gabriella (Journal article; Peer reviewed, 2012)
      Slag refining is one of the few metallurgical methods for efficient removal of boron from silicon. In industrial slag refining for production of silicon for photovoltaic applications, the relationship between the slag ...

    • Verification of Experimentally Determined Permeability and Form Coefficients of Al2O3 Ceramic Foam Filters (CFF) at High and Low Flow Velocity Using a CFD Model 

      Hassanabadi, Massoud; Kennedy, Mark W.; Akhtar, Shahid; Aune, Ragnhild E. (Journal article, 2018)
      Filtration using Ceramic Foam Filters (CFFs) is a method widely used to separate inclusions from molten aluminium. In the present work, the specific permeability and form drag coefficients of nominal 50 mm thick commercial ...
