摘　　要：通过测定焦炭光学组织和热性质,讨论了添加贫煤、贫瘦煤后焦炭光学组织的特征及其与焦炭质量之间的关系。添加贫煤、贫瘦煤后焦炭光学组织以细粒镶嵌和中粒镶嵌为主,类丝炭和破片含量相对较多,中等尺寸的焦炭光学组织结构单元更有利于焦炭强度的提高。通过回归分析,建立了焦炭质量预测模型,通过测定焦炭光学组织含量能够直接得到焦炭反应性和反应后强度。Through the measurement of optical organization and thermal property of coke,the relationship between the optical organization feature and quality of coke after the addition of lean coal and meagre and lean coal is discussed.After the addition of lean coal and meagre and lean coal,the optical organization takes the fine grain inlay and medium grain inlay as the main,silk like carbon and fragment are relative more.The optical organization structure unit of medium size coke is more favorable to improve the strength of coke.Through regression analysis the coke quality prediction model is established and the coke reactivity index and post reaction strength can be obtained directly through the measurement of coke optical organization content.
