【摘要】 粒度是煤重要的物理性质之一，煤的粒度影响着煤炭加工利用过程中的质量、传热和化学反应速率等，从而会影响其工艺性质。通过结合企业几种常用炼焦煤，对不同粒度煤样进行坩埚焦试验，对坩埚焦进行了焦炭质量测定，得出各煤样所炼坩埚焦特征。为实际生产中调整入炉煤粒度分布提供理论依据，从而可以进一步提高焦炭质量。更多还原

【Abstract】 Particle size,a critical physical property of coal,significantly influences quality,heat transfer,and chemical reaction rates during cokemaking process,thereby affecting its technological performance. This study conducted crucible coking tests on coal samples with kinds of particle sizes of commonly utilized coals in a coking plant. Comprehensive assessments of coke quality were performed to determine the characteristics of crucible coke derived from each coal sample. The findings provide theoretical guidance for optimizing coal particle size distribution in practical coking operations,enabling further improvements in coke quality.更多还原
