• A study of anode baking gas composition 

      Aarhaug, Thor Anders; Brandvik, Trond; Kjos, Ole Sigmund; Gaertner, Heiko; Ratvik, Arne Petter (Journal article; Peer reviewed, 2018)
      A method has been developed to measure gas composition inside the pit in open anode baking furnaces. The gas composition can be used to understand attack on and degradation of the refractory lining, baking behavior and ...
    • Autopsy of refractory lining in anode kilns with open and closed design 

      Brandvik, Trond; Wang, Zhaohui; Ratvik, Arne Petter; Grande, Tor (Journal article, 2018)
      Aluminosilicate refractory lining constitutes a major part of anode baking kilns, and during anode baking the lining is exposed to harsh conditions which limits the lifetime. Here, autopsies of refractory linings from both ...
    • Degradation of Refractory Lining in Carbon Anode Baking Furnaces 

      Brandvik, Trond (Doctoral theses at NTNU;2019:340, Doctoral thesis, 2019)
      Primary aluminium metal is produced by electrochemical reduction of Al2O3 at ~960 ºC, during which large amounts of carbon anodes are consumed. The anodes are thus constituting an important part of the production process. ...
    • Effects of Water Cooling of Green Anodes on Anode Furnace Operation 

      Brandvik, Trond; Ratvik, Arne Petter; Grande, Tor (Journal article; Peer reviewed, 2018)
      Water can be present in significant amounts in green anodes due to cooling with water after the forming process. The chemical environment in the pit can potentially be affected by the presence of water and may cause ...
    • Ferroelectric Transitions in SrxBa(1-x)Nb2O6 - Effect of Thermal History on the Functional Properties 

      Brandvik, Trond (Master thesis, 2015)
      Many functional materials used in todays electronic equipment have a high content lead. Due to the environmental challenges related to production and usage of such materials, extensive research has been preformed on lead-free ...
    • In situ monitoring of pit gas composition during baking of anodes for aluminum electrolysis 

      Brandvik, Trond; Gaertner, Heiko; Ratvik, Arne Petter; Grande, Tor; Aarhaug, Thor Anders (Journal article; Peer reviewed, 2019)
      Carbon anodes, which are consumed in aluminum electrolysis, are fabricated in separate anode plants where coke and pitch are mixed and vibrocompacted to green anode blocks before being baked in anode baking furnaces. The ...
    • Investigation of Spent Refractory Lining in an Anode Baking Furnace 

      Brandvik, Trond; Wang, Zhaohui; Ratvik, Arne Petter; Grande, Tor (Journal article; Peer reviewed, 2017)
      The refractory lining in anode baking furnaces is exposed to harsh chemical environment and thermal cycling. Spent refractory lining from an anode baking furnace after 4000 days in operation was investigated. Variation in ...
