粘结指数用无烟煤粉标准样品的研究

Study on standard anthracite sample used to determine caking index

通过对富源无烟煤、织金无烟煤、炼钢用增碳剂、宁夏汝箕沟无烟煤、昭通无烟煤进行取样、指标分析，并与标准无烟煤粉G值对比分析研究，得出昭通无烟煤可作为测定G值用无烟煤粉内控标准样品。

By sampling and analyzing Fuyuan anthracite, Zhijin anthracite, steelmaking carburant, Ningxia Rujigou anthracite, Zhaotong anthracite, and comparing their G value with that of standad anthracite, we concluded that Zhaotong anthracite can be used as internal standard anthracite sample to determine G value.
