摘要：为了提高焦炭质量,特别是焦炭反应性CRI和反应后强度CSR,从镜质组反射率角度研究了优化配煤炼焦的影响因素。通过对8种炼焦煤种的煤质分析、单独炼焦和配煤炼焦的焦炭质量分析与评价,阐述了不同煤种在配煤炼焦中所起的作用。通过分析某企业原配煤方案存在的问题,基于煤岩配煤原理,选择镜质组最大反射率(Rmax)及镜质组反射率分布图2个因素作为指导优化配煤的指标参数,制定了6组优化配煤方案进行炼焦试验。结果表明,配合煤的Rmax与镜质组反射率分布是优化配煤方案的有效调控指标,优化配煤方案获得的粒焦CRI*降低1.95%,CSR*增加3.45%,焦炭热态强度明显提高。
In order to improve the quality of coke,especially the coke reactivity index（ CRI） and coke strength after reaction（ CSR）,the influence factors of optimizing coal blending coking from the perspective of vitrinite reflectance were researched. The properties of eight kinds of coking coal was analysed,and coke quality were researched prepared by single coal and coal blending. The results showed that the effect of different coal on the coal blending coking was different. According to the principle of coal petrography blending,based on the analysis of the issues of previous coal blending scheme in a certain enterprise,the maximum vitrinite reflectance（ Rmax） and vitrinite reflectance distribution figures were selected to the guide of optimization of coal blending,and the six optimum schemes were put forward. The result showed that the blended coal＇s Rmaxand the reflectance distribution figures were two effective adjustment parameters of optimizing the coal blending. Through the optimization of coal blending scheme,particulate coke＇s CRI＊was decreased by 1.95% and CSR＊was increased by 3.45%,the coke＇s thermal strength was greatly improved.
