摘　　要：高炉大型化对焦炭质量提出了更高的要求,传统的焦炭质量评价方法具有一定局限性。总结了碱金属和镜质组反射率对光学组织的影响,阐述了各光学组织在成焦过程的演变规律以及对焦炭质量的影响,为预测和评价焦炭质量提供依据。With increasing capacity of blast furnace,higher coke quality is required forironmaking.Therefore the conventional method of coke quality evaluation has some limitation from this prospective.This paper summarizes the effect of alkali metals and reflectance distribution of vitrinite on optical texture,describes the evolution rules of each optical structure in coking process and its final influence on coke quality as well.It provides basis for reasonable prediction and scientific evaluation of coke quality.

关 键 词：光学组织 镜质组反射率 成焦规律 焦炭性能
