在生产突破层面，此次四条铸轧生产线试车成功，标志着“铝液不落地”工艺体系全面成型。依托煤电铝一体化闭环，电解铝液经真空台包直送铸轧车间，省去传统重熔环节，每吨铝减少损耗成本200元，项目一期可年产20万吨变形铝合金扁铸锭、10万吨铸轧带材，产品覆盖1-8系高端合金，直供航空航天、新能源汽车等领域。同时，合金分公司通过网格化管理破解建设难题，5轮工艺消缺解决71项设备隐患，4期全员培训覆盖核心技术团队，实现“人、机、料”协同运转，这种“挂图作战”模式使项目较计划提前进入试生产阶段，为2025年铝水转化率提升至25%奠定基础，真正实现从“铝锭”到“高端材”的效率革命。

在技术创新层面，项目凭借硬核实力破解行业痛点。其搭载与中南大学联合研发的7系铝合金技术，产品抗晶间腐蚀性能接近欧美顶级水平，打破航空航天领域高端铝材进口依赖，同步攻关的阳极炭渣脱碳技术更实现每吨碳渣新增产值6000元，被鉴定为“国际领先”。后续企业还将投资3.2亿元打造“黑灯工厂”，把8条旧生产线升级为4条32吨全自动铸造线，并引入5G+智能调度系统，改造后预计年节约成本超2800万元，设备自动化率将提升至行业领先水平，进一步激活效率潜力。

从产业升级维度来看，项目通过“五级延链”构建起独特的产业生态，上游衔接60万吨电解铝产能，下游联动春晨博发等加工企业，实现铝水就地转化年省运费千万元，“十四五”期间还将布局3万吨含钪铝合金棒材等二期项目，产品附加值较传统铝锭提升3-5倍，形成强大竞争壁垒。同时，企业依托“科学家+工程师”双驱体系，联合6所高校建成省级研发中心，36个在研项目斩获30项核心专利，研发投入连续三年增速超50%，构建起“基础研究-中试-产业化”全链条创新生态，以四链融合为煤电铝产业注入科技动能，推动产业价值重构。

从战略意义来看，该项目更是资源型城市转型的“榆林样本”。从毛乌素沙地的荒漠到年营收300亿元的工业绿洲，项目践行“煤电铝材”循环模式，煤炭发电支撑铝冶炼，铝加工吸纳电力产能，固废资源化实现“吃干榨尽”。这种转型路径不仅助力企业冲击“煤电铝一体化全国第一”目标，更成为陕西打造千亿级铝镁产业集群的核心引擎，为资源型地区产业升级提供了可借鉴的实践方向。
