十一冶承建的120台电解槽制安项目，是天山铝业140万吨电解铝绿色低碳能效提升改造工程的核心部分，该项目采用400kA级预焙阳极电解槽技术，单槽设计产能约540吨/年，120台全部投产后可形成约6.5万吨/年产能，占整体改造计划的4.6%，后续将通过多批次建设逐步释放140万吨升级产能，而20万吨电解铝富余指标建设目前尚未明确与本批次电解槽的直接关联，推测为独立扩产序列。

当前项目多维度进展显著，电解槽下部结构已完成组对焊接96台(占比80%)、安装及交验95台(占比79.2%)，精准控制误差在±1mm内，为槽体稳定奠定坚实基础;电解槽上部结构安装67台(占比55.8%)，集成了智能下料、阳极提升等核心系统;母线预制和安装完成50%，其电力传输效率直接影响吨铝电耗;炉窑专业完成52%，耐火材料抗侵蚀性能较传统工艺提升30%;220kV变电站(四系列)工程整体完成95%，将为电解槽启动提供稳定电力供应。项目关键时间节点明确，预计11月21日一阶段60台电解槽通电投产，投产后预计可实现日产能约90吨、年产能3.24万吨，对应产值约5.8亿元(按当前铝价1.8万元/吨测算)。

此次改造在技术上实现多重升级，通过“三维激光定位+智能振捣”技术，槽体密实度达98.5%，较传统工艺降低吨铝电耗约300kWh，年节电超1800万kWh;配套密封罩板与超浓相集气系统，氟化物捕集率达99%以上，符合《铝行业绿色低碳发展行动方案》要求;同时集成槽控系统升级改造，实现下料、阳极更换等工序自动化，引领行业智能管控标杆。

项目推进过程中，通过“穿插施工+双语技术团队”模式(培养本地工人120余名)，较计划提前12天进入扎固阶段，有效保障进度;落实领导带班与24小时值班制，累计排查整改隐患85项，实现“零事故”安全目标;建立2000㎡恒温材料仓库，成功应对新疆风沙、印尼雨季等极端环境对供应链的影响。

此次投产将带来多重价值，企业层面，天山铝业将新增绿色产能，预计吨铝成本下降800-1000元，年增利润超2600万元;行业层面，推动国内电解铝能效标杆从330kA向400kA级跃迁，为1.4亿吨产能改造提供可复制样本;区域层面，新疆项目助力西北新能源消纳，印尼项目(参考同类工程)年减碳80万吨，切实践行“一带一路”绿色倡议。
