摘　　要：采用煤镜质组反射率分布并结合常规煤质指标,对稳定和控制水钢焦炭质量进行了实验研究.对水钢的18个煤样进行了反射率及常规指标的检测、煤质分析与评价和炼焦实验;对水钢的生产方案及建议方案进行了40kg焦炉炼焦实验,并对其进行了分析;使用煤镜质组反射率分布并结合常规煤质指标为水钢制定了三个优化配煤方案,焦炭质量提高,完全满足生产要求.研究结果表明,煤镜质组反射率分布图是指导炼焦配煤的有效手段,对稳定和控制焦炭的热性质效果十分明显,对炼焦配煤煤种多和有混煤情况尤其适用和有效.For stabilization and control of coke quality of Shuicheng steel the research by application of reflectance distribution of coal vitrinite and traditional coal property parameters has been done. The reflectance determination of coal vitrinite, analysis and evaluation of coal proper- ties and coking test for eighteen coal samples have been carried out. The production coal blend in use and recommended coal blends at Shuicheng steel have been evaluated basesd on the test re- sults obtained from coking tests on 40 kg test coke oven. By application of reflectance distribution of coal vitrinate and traditional coal property parameters three optimum coal blends have been put forward. The coke quality is improved and satisfied with demands of production. The research shows that using the reflectance distribution diagram of coal vitrinite is an efficient means of guiding coal blending and especially effective in controlling and stabilizing coke property at high temperature. It is convenient to guide coal blending by using reflectance distribution diagram of coal vitrinite when charged coal is blended by many kind of coals and/or mixed coals.
