6月20日，‌随着火红的钢带呼啸而过，河南钢铁集团安阳基地成功完成当班最后一卷稀土耐候钢的轧制，标志着西部一新能源光伏工程首批次2000余吨稀土耐候钢订单全部生产完成。该钢种兼具‌易成型、抗腐蚀、低成本等核心优势，是河南钢铁集团在绿色高端材料研发领域的又一重大突破。

近两年来，河南钢铁集团锚定“高端化、智能化、绿色化”发展方向，以科技创新引领特钢转型。在此次稀土耐候钢研发过程中，坚持产学研用相结合，采取“一院多平台”协同机制，以河南省先进钢铁材料产业研究院为载体，联合上海大学、北京科技大学、东北大学等在安阳基地开展全流程攻关，最终实现高稀土含量耐候钢稳定连续生产。

稀土元素虽可显著提升钢材韧性和耐蚀性，但随着含量增加，钢水与氧、硫反应生成的难熔物会引发吸收率波动、连铸水口结瘤等问题，成为制约规模化生产的关键。为此，研发团队创新开发稀土合金精准添加与连铸防套眼集成技术，构建钢水纯净度控制体系，持续优化高精度薄规格板形控制，形成全流程质量管控方案。该技术有效解决稀土元素“难控制、高损耗、易粘结”的行业难题，推动河南钢铁集团稀土耐候钢从实验室研发迈向工业化生产。

值得一提的是，该稀土耐候钢通过低氧环境稀土合金化，结合高过热度、高拉速、强制冷却等集成连铸技术，首次实现热连轧多规格批量化生产。此外，该钢种经辊压成型+ ERW 高频焊接后，仍能保持材料均质化与组织性能稳定，填补了国内稀土耐候钢研发应用的又一空白。
