在“双碳”目标引领与山西省工业绿色转型浪潮中，中铝山西新材料铝加工厂以天然气消耗精准管控为突破口，深耕全流程节能降耗，交出了一份亮眼的绿色成绩单。截至11月底，该厂合金产品累计综合气耗同比降低7.03Nm³/t，在提升能源利用效率的同时，为企业高质量发展注入了强劲的绿色动能。

作为国家级绿色工厂的重要组成部分，该厂摒弃“单点节能”思维，构建起覆盖生产全链条的精细化管控体系，将节能理念渗透到每个工艺环节。在热能留存管控上，定期开展炉门密封专项检修，通过更换密封材料、优化闭合精度等措施，有效阻断热量外泄通道;针对铸盘烘盘工艺进行迭代升级，将传统烘盘时长压缩至15分钟以内，在保证烘盘质量的前提下大幅缩短能源消耗周期。生产调度环节更成为温度管控的“中枢神经”，通过精准协调各工序衔接，减少铝液抬包运输等待时间，确保铝液温度稳定在最优区间，让温度管控成为节能降耗的核心抓手。

能源高效利用与资源循环优化形成节能“双轮驱动”。蓄热球作为窑炉余热回收的关键元件，其清洁度直接影响助燃风预热效率。该厂建立每周蓄热球清理机制，通过定期疏通流道、去除积灰，确保助燃风流量稳定，使烟气余热回收效率提升至最优水平，显著降低天然气消耗。在铝液处理环节，优化后的扒渣工艺流程强化了铝、渣分离效果，减少铝液随炉渣带出造成的间接能源损耗;针对铝棒加工制定差异化物料管控标准，通过精准控制棒头棒尾切除长度，从源头减少自产回炉料产生量，降低二次熔炼能耗。同时，规范再生铝包装打捆标准，既提升了回炉转运效率，又有效减少了物料在转运过程中的热量散失，实现再生资源利用的“热损失最小化”。

这些举措的落地实施，是该厂践行中铝山西新材料“减量化、资源化、无害化”发展原则的生动实践。作为拥有完整铝产业链的央企子单位，铝加工厂的节能探索与公司赤泥“吃干榨净”、二次铝灰资源化利用等绿色技术形成协同效应，共同筑牢企业绿色发展根基。

下一步，中铝山西新材料铝加工厂将持续以技术创新为引领，深化生产流程优化，探索更多节能降耗新路径。在传承现有管控经验的基础上，积极对接行业先进技术，让绿色成为铝加工生产最鲜明的底色，为企业打造行业节能标杆、推动山西工业绿色转型贡献更大力量。
