The technical usage of the process described refers to converter steelmaking for the production of crude steel. This process primarily uses hot metal derived from iron ore and scrap steel as feed materials. The data set pertains to a specific unit process at a steelmaking facility, identified as Z1. This process is applicable in the manufacture of a wide range of steel products, from construction materials to automotive and machinery components. The steel produced through this process meets industrial-grade specifications and can be utilized in various manufacturing sectors. When utilizing this LCA data set for modeling the impacts of steel production, users should pay attention to the process's technological scope and specificity to the Z1 facility. Assumptions such as the proportion of hot metal and scrap steel used, energy source types, and emission controls need to be consistent with this facility's reality. The data set might not consider end-of-life recycling or the use phase of the steel; therefore, these stages should be modeled separately if relevant. Users should also take into account the technological evolution and potential improvements in the process that may have occurred after the data was compiled. For comparative studies, it is essential to ensure methodological consistency across different data sets.
