Description
Steam is a byproduct of the steelmaking process. Steel billets can serve as raw materials for downstream processes, being further processed through rolling, forging, and drawing into finished steel products of various specifications and shapes, such as steel plates, steel pipes, and steel bars. Steel billets are widely used in construction, machinery manufacturing, shipbuilding, and automobile manufacturing to produce various components and structural materials. The production process of steel billets includes electric arc furnace melting, molten steel refining, and casting and shaping of molten steel, covering energy consumption, material consumption, waste treatment, and environmental emissions during production. This dataset is formed by merging data from multiple sources. This dataset describes the scrap steel input in electric arc furnace steelmaking of approximately 0.43 kg/kg of steel.

Electric arc furnace (EAF) steelmaking is a method of steel production that utilizes the thermal effect of an electric arc to heat and melt raw materials. Electrical energy is introduced into the electric arc furnace through graphite electrodes, with the electric arc formed between the electrode tips and the charge serving as the heat source. EAF steelmaking primarily uses scrap steel as the main raw material, supplemented by alloys, lime, carbon raisers, and other auxiliary materials. The basic EAF steelmaking process includes slag removal and refractory lining repair, charging of metallic raw materials, power supply, melting, oxidation, reduction refining, and tapping. In this unit process, the scrap steel ratio in electric furnace steelmaking is approximately 40%.
