摘　　要：通过研究济钢焦化厂实验小焦炉炼焦用煤添加焦粉、沥青炼得的焦炭的气孔壁材料和气孔结构 ,揭示了焦炭显微结构光学性质和焦炭工艺之间的关系 ,证明了炼焦煤中添加适量焦粉能提高焦炭强度 ;沥青对促进异性碳的发展起着良好的效果。因此 ,在炼焦用煤中添加焦粉、沥青能起到改善焦炭质量的作用 ,同时节省煤源。Through the research on blowhole wall and blowhole structure of coke made with coking coal and coke powder and pitch additions in experimental small coke oven of Jigang coking plant, the relationship of optical characters for coke microstructure with coking process is given It tells us if appropriate coke powder is added, the strength of coke will be improved; and pitch can give a good effect for allo-carbon developing So if coke powder and pitch are added,the quality of coke can be improved and also save coal in coke making
