Abstract
The Aluminium Dunkerque smelter came on stream in 1991 with AP30 technology at 295 kA and since then the technology has been regularly improved to operate around 360 kA nowadays. In mid-2011two successive severe technical incidents took place in the Substation and limited the maximum Substation capacity to 285 kA for several months. To cope with this 20% amperage reduction and limit the risk of smelter stoppage, a major action plan was launched not only in the potrooms but also in the smelter as a whole. After adjustments on both operation and process sides, Aluminium Dunkerque has been able to continue operating the potline for 8 successive months at reduced amperage with satisfactory operating condition and technical results. This demonstrates the robustness and capability of the technology to operate at reduced power and paves the way for flexible power operation at AP Technology™ smelters.
