数据集使用建议 在使用直接还原铁生产路线的生命周期清单（LCI）数据时，确保适当地模拟特定技术（煤基直接还原Coal-DR, 天然气直接还原（MID）NG-DR (MID), 天然气直接还原（ENE）NG-DR (ENE), 焦炉气直接还原COG-DR, 氢直接还原H-DR）在过程中的应用。由于LCI是基于示范项目的平均运营数据，并辅以模拟、实验室测试和过程建模等文献数据得出的，用户应确认其使用环境与提供的中国基准相符。在准确性上，必须考虑规模化可行性、技术成熟度和区域可变性。对于在中国尚未完全规模化的路线，如COG-DR和H-DR路线，应额外注意将LCI数据适应于部署的特定环境。
产品或过程的技术目的 使用天然气直接还原（MID）方法生产的直接还原铁（DRI）主要用作炼钢的原材料。与传统高炉方法相比，天然气直接还原提供了一种更清洁、更节能的生产铁单元的方式，用于电弧炉（EAF）中或进一步加工成各种钢铁产品。
