Key Data Set Information
Location CN
Geographical representativeness description The data of the BF-BOF pathway were obtained from the large-scale integrated steel plants in China with an attached coking plant and EAF plant.
Name
Molten iron production;Molten iron;BF
Use advice for data set Users of this dataset should ensure that the BF-BOF pathway data is applied to scenarios appropriate for large-scale steel production with coke-based ironmaking. Attention should be paid to the specific process parameters from the region's integrated steel plants, as they may affect the environmental impact assessment. Recycling scenarios, if to be included, should consider the use of the EAF plant for steel scrap melting, which can alter the energy profile and emissions of the overall steel production process. The timeframe and geographical scope of data collection should be considered when applying this dataset to ensure relevance and accuracy in Life Cycle Assessments (LCA).
Technical purpose of product or process This dataset describes the molten iron production process in a Blast Furnace (BF) unit operation, specifically for large-scale integrated steel plants in China. The molten iron (also known as hot metal or pig iron) is primarily used for steelmaking in Basic Oxygen Furnaces (BOF) or can be cast into ingots for further processing. The presence of an attached coking plant suggests the production of coke, which is necessary for the BF process, and the existence of an Electric Arc Furnace (EAF) indicates the potential for recycling steel scrap.
