Аннотация: UC RUSAL remains one of the world's leaders in primary aluminium producing eight percent of total world output in 2013. In 2012, following the global industrial trends, Management initiated several technical projects with the goal to decrease power consumption in all reduction technologies used. Below are the major measures: 1. EneПоказать полностьюrgy balance adjustment to reduce heat generation by a stage-by-stage decrease in the anode-cathode distance (ACD) down to the Limit values, resulting in the specific power consumption has decreased by 300 DCkWh/t. 2. The introduction of slotted anodes for the PB cells at the Krasnoyarsk and Irkutsk smelters decreasing specific power consumption by an average of 200 DCkWh/t. 3. Advanced energy-saving cathode designs are currently tested with a potential for decreasing 300 DCkWh/t or more. The rest of this paper will describe how these projects decreased the specific power consumption in all RUSAL smelters between 2013 and 2014.
