摘　　要：对水钢分为6大类的18个生产用煤进行了镜质组反射率分布及常规煤质指标检测,对煤质指标和炼焦实验结果作了分析及评价,指出保华大类煤是影响水钢焦炭质量的主要因素,建议对其分三组堆放使用.据此,使用煤镜质组反射率分布并结合常规煤质指标为水钢制定了3个优化配煤方案,其焦炭质量明显提高,优于水钢的生产方案.研究结果表明:煤镜质组反射率分布图是指导炼焦优化配煤的有效手段,对稳定和控制焦炭质量特别是焦炭的热性质效果十分明显.对于炼焦配煤煤种多、有混煤情况时尤其适用和有效.The reflectance distribution of coal vitrinite and other coat properties of eighteen individual coals of Shuicheng Steel which are classified into six groups has been determined and analyzed. The analytical resuhs of coal properties and coking tests for the eighteen individual coal samples have been analyzed and evaluated. The test results show the coals of Baohua group are the main factor which influences coke quality of Shuicheng Steel. So it is suggested the coals of Baohua group are divided into three sub-groups and stacked separately in three coal piles for coal blending. Three optimum coal blend schemes have been put forward based on reflectance dis- tribution of coal vitrinite and common property parameters of coal. The coke quality is improved obviously and much superior to that of current production coal blend at Shuicheng Steel. The research shows that using the reflectance distribution diagram of coal vitrinite is an effective means of guiding optimization of coal blending and especially effective for controlling and stabilizing coke property at high temperature. It is useful and more convenient to guide coal blending by using re flectance distribution diagram of coal vitrinite when there is a lot of kind of coals and/or there are mixed coals for blending.
