Application of SAMI Energy-Saving and Current-Intensifying Technology in a 330 kA Potline

China’s strategic goal of “Dual-Carbon” has put forward the requirements of “dual control of both energyEnergy consumption and intensity” for the aluminum smeltingAluminum smelting industry. Under these circumstances, Shenyang AluminumAluminum and MagnesiumMagnesium Engineering and Research Institute Co., Ltd. (SAMI) has carried out a series of technical research and upgrading projects since 2015. In 2022, Laibin Guangtou Yinhai AluminumAluminum Co., Ltd. implemented an upgrade project on their 330 kA potline using SAMI’s proprietary technology. This project involved adopting various technical strategies from SAMI, such as Networked Self-Equalizing Busbar Technology (NSBT), New Conceptual CathodeCathode Technology (NCCT), “Long Healthy Life”\“Long Healthy Life\” pot lining designPot lining design, etc. The current of this potline was increased to 350 kA, and the energyEnergy consumption of liquid primary aluminumAluminum was reduced to 12,520 kWh/t-Al from 13,182 kWh/t-Al. These technologies offer strong technical support for the existing aluminum smeltersAluminum smelter to upgrade their current low-amperage reduction cellsCell, leading to lower carbon emissions.
