• Effects of Compaction and Thermal Pre‑treatments on Generation of Dross and Off‑Gases in Aluminium Recycling 

      Vallejo Olivares, Alicia; Gertjegerdes, Tom; Høgåsen, Solveig; Friedrich, Bernd; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)
      Organic coatings are a challenge for aluminium packaging recycling since they tend to increase the re-melting metal losses. A solution is de-coating the scrap via a thermal pre-treatment to burn-off the organics before ...
    • Inverse modelling of interfacial tension between ferroalloy and slag using openfoam 

      Bublik, Sergey; Einarsrud, Kristian Etienne (Chapter, 2020)
      The entrainment of molten ferroalloy droplets in slag during tapping operations is strongly related to turbulence and interfacial forces between alloy and slag. Therefore, interfacial phenomena are of great importance for ...
