摘　　要：对各国和地区采用基氏塑性仪测定煤的流动度的相关标准进行了研究,美国、日本等国和地区的研究较为完善。比较分析了各国煤的基氏流动度测定标准的不同之处,除部件精确度要求有差别外,最主要的不同之处为煤甑坩埚底部中心凹槽坡口角度不同,这就产生了搅拌桨与坩埚底部的不同接触方式。总结了中国煤的基氏流动度测定标准以及基氏流动度测定仪研制过程中存在的主要问题及应用、发展现状。研究表明,基氏流动度的测定尚未有相关的国家标准,而国内测定仪多为国外进口,国内研制的设备精度不高,检测效率较低;在煤的流动度指标应用上,日本等国将其用于指导配煤炼焦、预测焦炭质量,而中国也在这些方面逐渐进行研究。Research the standards of coal Gieseler fluidity tested by Gieseler plastometer in many different countries,which is more advantage in America and Japan.Compare the differences of standards in different countries,found that besides the requirement of parts precision of Gieseler plastometer was slightly different,the primary difference was the angle of V shape notch in the central of crucible base,which would lead to a different contact way of steel stirrer and retort crucible bottom.Summarize the main issues in the process of setting coal Gieseler fluidity,also introduce its application and development.There are no national measuring standards in China to guide the test,the Gieseler plastometers are mainly imported from abroad,the precision of domestic equipments is low.Gieseler fluidity of coal was used for coals blending and predicting the coke quality in Japan and other countries,and similar researches had also been carried out gradually in China.
