It covers a complete sequence of unit processes from bauxite mining and bauxite transport, through Bayer alumina refining, alumina transport, aluminum electrolysis, molten aluminum transport, ingot melting and casting with homogenizing annealing, followed by hot rolling, cold rolling, foil rolling and final O-state annealing of the foil. The network of process instances is consistently constructed: upstream–downstream links are established via shared flow UUIDs, resulting in a coherent system configuration with a clearly defined reference process. Metadata are comprehensive, including intended applications (carbon footprint and environmental impact assessment of aluminum products), commissioner information, versioning and a permanent URI. The model explicitly declares compliance with ISO 14040/14044 and is supported by a dependent internal review and a referenced full review report, indicating good methodological and structural robustness. Overall, this life cycle model shows high quality in terms of process coverage, connectivity logic, formatting and review documentation, and is suitable for inclusion in the database and for scenario analysis of aluminum foil production. 常慧敏 Chang, Huimin 模型数据集“铝箔生产；铸锭热轧法，铝液浇铸、加热、热轧、冷轧、箔轧等多道次加工最终制备成铝箔产品; 生产混合，在工厂”审查报告 Review report of modeling datasets "Aluminum foil production；Continuous casting hot rolling method, Aluminum foil products are finally prepared through multiple processing steps such as molten aluminum casting, heating, hot rolling, cold rolling and foil rolling；Production mixing, in the factory" Fully compliant Not defined Not defined Not defined Fully compliant Fully compliant ISO 14040 Environmental Management – Life Cycle Assessment – Principles and Framework, 2006 ISO 14040 Environmental Management – Life Cycle Assessment – Principles and Framework, 2006 Fully compliant Not defined Fully compliant Fully compliant Not defined Not defined 2025-07-25T14:21:50+08:00 ILCD format ILCD 数据格式 王楠 Wang Nan No Free of charge for all users and uses 01.01.000 https://lcdn.tiangong.earth/datasetdetail/process.xhtml?uuid=7f673a16-5901-4834-bb69-207bbb20a67c&version=01.01.000 TianGong Think Tank 天工智库中心 本过程数据拟用于铝产品全生命周期碳足迹核算及环境影响评价，适用于科研、政策研究及企业绿色评估项目。可用于生命周期评价（LCA）、产品碳足迹（CFP）、绿色供应链管理等环境可持续性研究，服务于行业低碳转型与碳减排路径制定。 The data from this process are intended for the carbon footprint accounting and environmental impact assessment of the entire life cycle of aluminum products.
