近日，随着最后一榀跨度达53.25米、重35.7吨的钢桁架精准就位并完成焊接固定，中国六冶公司承建的内蒙古通辽市扎哈淖尔35万吨绿电铝项目(以下简称“扎铝二期”)氧化铝仓库及输送系统钢支架、钢桁架吊装作业圆满收官。这一关键节点的完成，标志着该项目核心结构施工任务全面告捷，为新老厂区联动运营、氧化铝高效输送搭建起坚实桥梁，更为我国北方绿色铝产业发展注入新动能。

作为国家电投布局绿电铝产业的重点工程，扎铝二期项目以“绿电赋能、低碳生产”为核心定位，预计年用电量约46.5亿千瓦时，其中绿电占比超80%，投产后每年可减排二氧化碳约120万吨，将成为国内绿电占比最高的绿电铝生产线之一。此次六冶完成的吊装工程，正是该项目重要的配套枢纽，涵盖1#、2#斗提间及钢桁架输送系统，核心任务为新老厂区间钢柱与钢桁架的制造安装，直接关系到氧化铝原料输送的连续性与稳定性。

该工程的技术难度与安全风险尤为突出。施工共涉及7榀大跨度钢桁架，跨度覆盖37.8米至53.25米，单榀最重达35.7吨，所有钢结构均采用焊接连接工艺以保障整体稳固性。更具挑战的是，施工区域需跨越新老电解车间，作业空间狭窄且周边生产设施密集，对吊装精准度和现场协调能力提出极高要求。

面对多重考验，六冶项目团队以“方案先行、创新破局”为思路，提前细化施工组织设计，优化构件加工与场内布局方案。为提升效率并降低现场作业风险，团队采用“场外精细化加工+场内就近组装”模式，在老厂区专门设置两个组装区，实现构件高效转运与快速衔接。起重设备方面，项目启用800吨汽车吊作为主吊机械，通过精准测算吊装轨迹、动态调整作业参数，确保每榀钢桁架都实现毫米级就位，这一施工经验为后续大跨度钢结构安装工程提供了宝贵借鉴。
