摘要

为明确电炉炼钢能耗的影响因素及优化方向，本研究建立了完整的质量和能量平衡模型，包括渗透空气和废气流量测量模型、辐射和对流热损失模型，用于预测电炉炼钢的功率和耗氧量。讨论了供电、供氧、喷碳、渗透空气、铁水充注等对电弧炉能耗的影响。结果表明，优化生产参数可以有效降低能耗，特别是在可燃气体充足的情况下提高渗透空气流量，有利于节能减排。此外，由于铁水生产上游过程的能源和碳投入较大，铁水加料电炉的能耗和碳排放量远高于100%废料加料电炉。

Analysis and optimisation on the energy consumption of electric arc furnace steelmaking

ABSTRACT To clarify the influence factors and optimization direction of energy consumption of EAF steelmaking, this study established a complete mass and energy balance model, comprising infiltrated air and off-gas flowrate measurement model and radiative and convective heat loss model, to forecast power and oxygen consumption. The influence of power supply, oxygen supply, carbon injection, infiltrated air, and hot metal charging on the power consumption of EAF is discussed. The results show that optimizing production parameters will effectively reduce power consumption, especially improve the infiltrated air flowrate when there are sufficient combustible gases, which is conducive to energy conservation and emission reduction. Additionally, due to the intensive energy and carbon input in the upstream process of hot metal production, the energy consumption and carbon emissions of hot metal charging EAF are much higher than those of 100% scrap charging EAF.
