Abstract
Pursuing the goal of designing high performance, high productivity and low capital cost cell technology, Aluminium Pechiney re-engineered its well known AP30 reduction cell to create an advanced cell operating at about 350 kA and called AP35. Following the avenue opened with the re-engineered smaller sister cell AP21 [1], the AP35 design integrates the latest development in lining design, anode assembly and sidewall ventilation.
Several test pots have been operating for four years, with the last 18 months at 350 kA, at the Saint-Jean de Maurienne smelter, allowing for extensive industrial trials of various designs and material variations. Technical performances are presented and discussed.
The new cell technology is also available for retrofitting current AP30 potlines, providing extra production output (compared to an average operation at 325 kA) with modifications depending on the technical limits of the existing facilities.
