The molten steel production process described in this dataset is utilized in the production of steel using the Basic Oxygen Furnace (BOF) method. It is a single operation unit process that is typically used in large-scale production facilities to convert raw materials, such as pig iron and scrap steel, into refined steel. This process is common in the manufacturing of a variety of steel products, including construction materials, automotive components, and appliances. When using this dataset for Life Cycle Assessment, ensure that the production data is relevant to the geographical and technological context of the assessed product or process. Since the dataset is based on the production data from a specific steel plant in the year 2014, users should apply caution when generalizing the results to other contexts or time frames. Attention should also be given to the inclusion or exclusion of recycling in the system boundary, and to the specific energy requirements and emissions associated with the BOF steel production process.
