Electric arc furnace (EAF) steelmaking is a method that primarily uses scrap steel as the raw material, along with auxiliary materials such as lime and ferromanganese-silicon alloy, melting and refining the charge by introducing a powerful electric current into the furnace. The process represented by this dataset produces recycled steel billets through electric arc furnace smelting, ladle furnace (LF) refining, and continuous casting. Process water mainly includes equipment cooling circulating water discharge and direct cooling water discharge from rolling processes; the wastewater is recycled and not discharged externally. Atmospheric pollutants consist of particulate matter generated during production, which, after treatment by control devices, releases residual particulate matter into the atmosphere. Steel slag and iron oxide scale slag in solid waste can be sold as by-products, while EAF dust and waste oil are hazardous wastes and shall be handed over to qualified enterprises for treatment.
