煤的基氏流動(dòng)度測(cè)定標(biāo)準(zhǔn)及測(cè)定儀
發(fā)布時(shí)間：2012-05-04 點(diǎn)擊次數(shù)：1494次對(duì)各國(guó)和地區(qū)采用基氏塑性儀測(cè)定煤的流動(dòng)度的相關(guān)標(biāo)準(zhǔn)進(jìn)行了研究，美國(guó)、日本等國(guó)和地區(qū)的研究較為完善。比較分析了各國(guó)煤的基氏流動(dòng)度測(cè)定標(biāo)準(zhǔn)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?？偨Y(jié)了中國(guó)煤的基氏流動(dòng)度測(cè)定標(biāo)準(zhǔn)以及基氏流動(dòng)度測(cè)定儀研制過(guò)程中存在的主要問(wèn)題及應(yīng)用、發(fā)展現(xiàn)狀。研究表明，基氏流動(dòng)度的測(cè)定尚未有相關(guān)的國(guó)家標(biāo)準(zhǔn)，而國(guó)內(nèi)測(cè)定儀多為國(guó)外進(jìn)口，國(guó)內(nèi)研制的設(shè)備精度不高，檢測(cè)效率較低；在煤的流動(dòng)度指標(biāo)應(yīng)用上，日本等國(guó)將其用于指導(dǎo)配煤煉焦、預(yù)測(cè)焦炭質(zhì)量，而中國(guó)也在這些方面逐漸進(jìn)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
