Abstract: China has entered a new stage of economic development while facing the “double carbon” development strategy， the development of full waste steel electric arc furnace steelmaking is China's iron and steel industry to carry out structural adjustment of steel production process is an inevitable choice， For a long time the production efficiency of electric arc steelmakin is lower than that of converter steelmaking is a key constraint on the development of its key factors， exploring the key factors affecting the production efficiency of electric arc furnace steelmaking is conducive to the healthy development of electric arc steelmaking production；By establishing the calculation formula of the production efficiency of electric arc furnace， analyzing the key factors affecting the production efficiency of electric arc furnace steel production， and then confirming with the actual production of statistical data corroboration， the result show that， China's modern electric arc furnace steel production efficiency has made great progress. Through equipment large-scale and efficient smelting technology， it can make the electric arc furnace steelmaking production efficiency with the same tonnage converter steelmaking production efficiency （200 t/h）. The decisive factor affecting the production efficiency of electric arc furnace steelmaking is the electric arc furnace steelmaking process of energy supply power. In the impetus of material conversion， only improve the electric arc furnace steelmaking process total energy supply can not directly improve its productivity， only to improve the electric arc furnace in the process of energy supply power， can input energy into improve the impetus of material conversion.

摘要： 中国进入新的经济发展阶段，同时面临“双碳”发展战略，发展全废钢电弧炉流程是中国钢铁工业进行钢铁生产流程结构调整的必然选择。长期以来，电弧炉炼钢生产效率低于转炉炼钢是制约其发展的关键因素之一，探究影响电弧炉炼钢生产效率的关键因素有利于电弧炉炼钢生产的健康发展；通过建立电弧炉炼钢生产效率计算公式，分析影响电弧炉炼钢生产效率的关键因素，再与实际生产统计数据相印证，结果表明，我国现代电弧炉炼钢生产效率有了长足进步。通过设备大型化和高效化冶炼的技术手段，可以使电弧炉炼钢生产效率达到与同吨位转炉炼钢生产效率相当的水平（200 t/h），影响电弧炉炼钢生产效率的决定性因素是电弧炉炼钢过程的能量供应功率，在提高物质转化的推动力方面，仅提高电弧炉炼钢过程总能量供给不能直接提高其生产率，只有提高电弧炉炼钢过程中的能量供应功率，才能将输入能量转化为提高物质转化的推动力。
