Aluminium Tapping and Molten Metal Handling in Primary Smelters: John Grandfield1; Sam Wagstaff2; Bob Wagstaff2; 1Grandfield Technology Pty Ltd.; 2Oculatus Consulting
    This paper presents a review of tapping and melt handling technology of aluminium for those more familiar with steel and iron. The practice for light metals is substantially different to that used for iron and steel. For primary production using the Hall-Heroult technology, a variety of methods are used at the various stages of cell tapping, crucible transfer to the cast house, ladle treatment, liquid transfer to furnaces, furnace tapping and flow control during casting.. Level sensor technology is examined including mechanical systems, lasers and capacitors. Refractory types and melt interactions are also covered. Trough design is covered. Future developments such as automated furnace skimming are mentioned.
