煤的基氏流動度測定標準及測定儀
發(fā)布時間：2012-05-04 點擊次數(shù)：1456次對各國和地區(qū)采用基氏塑性儀測定煤的流動度的相關標準進行了研究，美國、日本等國和地區(qū)的研究較為完善。比較分析了各國煤的基氏流動度測定標準的不同之處，除部件精確度要求有差別外，最主要的不同之處為煤甄坩堝底部中心凹槽坡口角度不同，這就產(chǎn)生了攪拌漿與坩堝底部的不同接觸方式。總結(jié)了中國煤的基氏流動度測定標準以及基氏流動度測定儀研制過程中存在的主要問題及應用、發(fā)展現(xiàn)狀。研究表明，基氏流動度的測定尚未有相關的國家標準，而國內(nèi)測定儀多為國外進口，國內(nèi)研制的設備精度不高，檢測效率較低；在煤的流動度指標應用上，日本等國將其用于指導配煤煉焦、預測焦炭質(zhì)量，而中國也在這些方面逐漸進行研究。
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
