Anode design modification is an attractive option to enable increased amperage via reduced voltage losses. The stub to carbon connection can be modified cheaply and relatively quickly to achieve worthwhile improvement. However, if not done properly, anode design modification can adversely affect anode integrity. Checks are required to ensure compatibility with the existing rodding processes and handling equipment. Validating improvements of tens of millivolts in the smelter environment is extremely difficult in the relatively noisy electrical circuit of an operating reduction cell. Furthermore, an in-plant trial for anode design modification has logistical challenges that need to be managed.
This paper describes a series of in-plant checks and measures within reduction lines and the carbon rodding room, as well as off-line validation, to ensure a statistically valid result for an anode design modification.
