摘　　要：为稳定控制湘钢焦炭热性能,分析了影响焦炭热性能的主要因素,确定炼焦煤质量是影响焦炭热性能的关键因素。研究了焦炭显微结构调节技术、炼焦煤精细分类技术、配煤结构优化技术等焦炭热性能控制技术。分析了湘钢主焦煤、肥煤的成焦显微结构及焦炭热性能,针对炼焦煤质量和配煤结构存在的问题进行了生产配煤结构优化,2016年—2020年焦炭反应后强度逐渐从65.6%提高到67%以上,稳定率逐渐从74.1%提高到97%以上。In order to make stable control of the thermal properties of Xiangtan Iron&Steel Co.,Ltd.(Xianggang)coke,the main factors affecting the coke thermal properties were analyzed,and the quality of coking coal was considered to be the key factor affecting such properties.The coke thermal property control technologies were studied,such as coke microstructure adjustment technology,coking coal fine classification technology and coal blending structure optimization technology.The coking microstructure and coke thermal properties of the main coking coal and fat coal of Xianggang were analyzed,and in view of the problems of coking coal quality and coal blending structure,the production coal blending structure was optimized.From 2016 to 2020,the post-reaction strength of coke gradually increased from 65.6%to more than 67%,and the stability rate gradually increased from 74.1%to more than 97%.The thermal property index and stability rate of coke were obviously improved.
