以某焦化公司多种炼焦生产用煤为样本,测定其镜质组平均最大反射率R- max 、高温塑性和成焦光学组织结构,重点对影响中等变质程度炼焦煤结焦性的因素进行探讨。结果表明,单种煤成焦中,中粒+粗粒镶嵌组织、细粒镶嵌组织、完全纤维+片状组织的含量随炼焦煤变质程度的增加均呈现出规律性变化;相同变质程度炼焦煤的结焦性与其高温塑性密切相关,在R-max为0.9%~1.4%的单种煤成焦中,粗粒+中粒+细粒镶嵌组分之和随煤的最大基氏流动度对数值的提高呈增多趋势,丝质和破片+各向同性组分之和随煤的最大基氏流动度对数值的提高呈减少趋势;变质程度和高温塑性是影响中等变质程度炼焦煤结焦性的主要因素。

Coking coals used in a certain coking plant were taken as samples and their mean maximum reflectance of vitrinite ,high-temperature plasticity and coking optical texture were studied with the focus on the factors that influence the coking property of coking coals with medium metamorphic grade .The results show that ,in single coal coking ,the contents of medium plus coarse grained mosa-ic ,fine grained mosaic and fiber plus sheet component displays a certain pattern of variation with the increase in metamorphic grade of coking coals ,and coking property of coking coals of the same meta-morphic grade is closely related to their high-temperature plasticity .In single coal coking of coals with mean maximum reflectance of vitrinite at 0 .90% ~ 1 .40% ,the total amount of medium-,coarse-and fine-grained mosaic components tends to increase with the maximum Gieseler fluidity of the coals while the total amount of inert and isotropic components tends to decrease .Metamorphism and high-temperature plasticity are the main factors that influence the coking property of coking coals of medi-um metamorphic grade .
