Use advice for data set When using this dataset for Life Cycle Assessment (LCA) purposes, ensure the system boundaries are properly defined to include the impacts of raw material acquisition (hot metal and scrap steel) and the converter steelmaking process itself. Take into account the energy consumption and emissions associated with each stage. If assessing end-of-life scenarios, consider the potential for recycling the steel provided by this process, including any benefits or burdens associated with the recycling system. This should align with the methodological approach defined in the LCA study, such as ISO 14040/14044 standards.
Technical purpose of product or process This dataset represents a steelmaking process used to produce crude steel from a mixture of hot metal and scrap steel in a converter furnace. The steel produced is suitable for a wide range of construction, automotive, and manufacturing applications, as crude steel serves as a fundamental building material for various steel products and components.
