【摘要】 围绕现阶段由于废钢材料价格以及生产用电费用高等导致电弧炉高铁水比冶炼成本高于转炉冶炼的问题，结合企业生产相关数据，通过实际生产数据的热平衡及物料平衡计算结果，对电弧炉高铁水比冶炼和传统的转炉炼钢进行各方位比较，得出了电弧炉生产成本高的原因主要为钢铁料消耗高、生产节奏慢等。在对数据的综合分析和理论计算后，从余热利用、渣型优化和操作制度等方面对现阶段存在的问题提出了优化与改进的方向，可以为电弧炉高铁水比冶炼工艺改进方向提供参考。同时电弧炉冶炼也应当利用好其无渣出钢的优势，开发高质量品种钢，提高其市场竞争力。更多还原

【Abstract】 Addressing the current issue where high scrap material prices and elevated electricity costs render high hot metal ratio Electric Arc Furnace(EAF) steelmaking more expensive than Basic Oxygen Furnace(BOF) production, this study utilizes actual plant operational data.Based on thermal and mass balance calculations derived from this data, a comprehensive comparison between high hot metal ratio EAF steelmaking and conventional BOF steelmaking was conducted.The analysis identified higher raw material consumption and slower production rhythm as the primary reasons for the increased cost of the EAF process.Following integrated data analysis and theoretical calculations, optimization and improvement directions are proposed for the identified issues, focusing on waste heat recovery, slag regime optimization, and operational practices.These suggestions provide valuable references for enhancing the high hot metal ratio EAF process.Concurrently, EAF steelmaking should leverage its inherent advantage of slag-free tapping to develop high-grade specialty steels, thereby strengthening its market competitiveness.更多还原
