New heating solution for primary aluminium production
By replacing gas burners with Kanthal electrical heaters in the rodding shops of a primary aluminum plant, operators can slash their energy consumption and generate significant environmental and safety benefits.
The Kanthal electrical heating system provides major improvements over gas burners at critical stages in the rodding shop, from the moment before the rod attachments take place to pre-heating of the cathode block. With the exception of the anode stub drying station, the Kanthal heating solution includes a heating element located in a reflector arrangement. This allows the radiation to be more accurately directed towards the target area – a highly efficient heating method.
The Kanthal heating solution for primary aluminium rodding shops include stations for:
- Anode stub drying
- Anode pre-heating
- Ladle drying, ladle pre-heating and ladle holding
- Cathode pre-heating
