摘　　要：当前中国大型高炉的炉况波动较多,影响高炉技术经济指标提升,造成上述问题的原因主要是原燃料质量变化、炉料结构的调整以及适应原燃料质量下降条件下的低燃料比操作。且高炉操作制度频繁调整后高炉稳定性没有得到有效改善,除了仍应采取精料方针及排除环境干扰以外,高炉生产效率的有效评价对优化高炉各项指标及提高稳定性具有重要的意义。使用评价高炉生产效率的新方法统计分析了2016年4 000 m3高炉的生产数据,研究结果可为生产管理、技术人员、操作人员寻求合理的高炉操作制度提供依据。The large blast furnace conditions in China were changed largely in those days because of the variation of burden quality,burden structure and the lower fuel ratio adaption,affecting the operation indexes and economic profits. While the stability of blast furnace was worsening by frequently change the operation system. Except insist the high burden quality policy and eliminate the environmental interference,the effective evaluation of blast furnace production efficiency could benefits to optimize the operation indexes and improve stability of the blast furnace. In the present study,a new effective evaluation method was used to analysis the operation indexes of large blast furnace in China during 2016,the results could guide the operators and relative technician to find the reasonable operation systems for large blast furnace.
