VHE has completed the fabrication and installation of a preheating furnace for the Rio Tinto Alcan smelter at Straumsvík in Iceland.
The furnace is in the casthouse and will be used to preheat aluminium scrap before it is added to new aluminium in the melting furnaces, ensuring that all moisture has been removed and minimising the risk of steam explosions.
The furnace, which is semi-automatic, is able to heat 15 tonnes of scrap to 200°C within 2 hours. The oven is electrically heated and uses the recirculating air principle for best efficiency.
