Abstract Scope Furnace circulation is well accepted throughout the aluminum industry to maximize productivity while minimizing energy and dross generation. New furnace installations are typically fitted with some form of circulation technology; however, there are many older furnaces that rely on mechanical stirring with fork trucks which is inefficient and can cause significant refractory damage. While capital costs of retrofitting a circulation device to an existing furnace can be significant, return on investment can be quick. The SIBERFORCEŽ electromagnetic stirrer supplied by ALTEK is air-cooled and developed to overcome the negative aspects of traditional EMS devices such as high power consumption and maintenance of water cooled copper tubes. This paper details the retrofit of a SIBERFORCEŽ system to the bottom of a melting furnace at Hydro-Henderson. It also reviews the work required during installation and the results of performance testing that benchmarked improvements in melt rate, specific energy consumption and dross generation.
