摘　　要：为积极响应国家双碳目标,进一步提高500 kA电解系列的技术经济指标,通过在大修时,采用以全石墨化炭块为主材的内衬优化改造方案。通过该实施方案与原有的双钢棒石墨质进行理论和实践的对比,新的石墨化阴极方案实施过程取得较好的技术指标和经济效益,实现了节能降耗目标。In order to actively achieve the national dual carbon targets and improve techno-economic indicators of the 500 kA potline,the lining is optimized with fully-graphitized carbon blocks as main materials during the relining process.Through the theoretical and practical comparison between the execution plan and the original double steel bar graphitic cathode,the new graphitized cathode plan achieved better technical indicators and economic benefits,as well as achieved the target of energy saving and consumption reduction..
