6月29日，中铝国际长沙有色冶金设计研究院有限公司在铜冶炼技术领域取得重要突破，成功开发出40万吨级以上超大规模双熔池连续炼铜成套技术及装备。该技术不仅攻克了多项行业核心难题，更在广西南国铜业二期项目中实现工业化应用，已稳定运行近两年，年产能超过40万吨，显著提升了原生铜冶炼的低碳清洁生产水平。中铝集团首席工程师吴晓松介绍，面对铜冶炼行业原料日趋复杂、成本压力增大和环保要求日益严格的新形势，传统富氧侧顶吹双熔池冶炼工艺虽具低碳高效优势，但存在“规模天花板”与“能效瓶颈”的双重制约。项目组自主研发全球首套70平方米富氧侧吹连续造锍熔池熔炼装备和120平方米多枪顶吹铜锍连续吹炼装备，首创单系列40万吨级以上超大规模双熔池连续炼铜技术，成功解决了耐材热膨胀叠加、熔炼烟气系统结渣、吹炼炉底金属渗漏等关键技术难题，实现单线产能突破40万吨/年。这一技术的成功应用，不仅提升了我国铜冶炼行业的国际竞争力，也为该领域开辟了一条全新的超大型铜冶炼技术新路径。
