Using Surplus Heat to Pre-Heat Carbon Anodes for Aluminium Electrolysis
Grimstad, Martin (Master thesis, 2019)Karbon anoder brukes opp i Hall-Héroult prosessen og må erstattes regelmessig. Når en ny anode blir plassert i aluminiumsovnen, vil badet umiddelbart fryse på undersiden av anoden og danne et fryst isolerende lag. Denne ... -
Utilization of waste heat for pre-heating of anodes
Einarsrud, Kristian Etienne; Grimstad, Martin; Elstad, Kim Ronny; Solheim, Asbjørn (Peer reviewed; Journal article, 2020)Carbon anodes are replaced on a regular basis in Hall–Héroult cells as they are consumed by electrochemical reactions. Upon insertion of new anodes, bath will freeze locally as a result of low bath superheat and comparatively ...
