【摘要】 分析测定了7种炼焦煤的煤岩显微组分、显微煤岩类型及其焦炭的显微结构,发现有机组分基质中,矿物质均匀分布有利于成焦,而团块或大颗粒矿物质分布不利于成焦,显微矿化类型比例较高、显微矿质类型比例较低的高灰焦煤和肥煤仍具有良好的成焦性能,可作为配煤使用;气煤和瘦煤的显微矿化类型比例对其成焦性影响较小。更多还原

【Abstract】 Maceral and microlithotype of seven coking coal samples,and the microstructure of their corresponding coke are analyzed.It is found that well distributed mineral is good to coke forming,while lump or large particles of mineral have bad effect to coke forming.Coking coal with high ash content and fat coal,if with high proportion of carbominerite and low minerite,have good coking property,and can be used as blends for coke production.Comparatively,the proportion of carbominerite in gas coal and lean coal has little effect on their coking property.更多还原
