摘要
对采集了来自全国11个焦化企业的16个批次焦炭样品,进行了焦炭热态反应性和焦炭灰分组成的分析。研究结果表明:灰分中5种金属氧化物(含Na、Mg、K、Ca、Fe)表达的碱度指数MBI,与焦炭热态反应性之间存在一定关系,其线性斜率为511.4,相关系数为0.628;7种金属氧化物(含Na、Mg、K、Ca、Fe、Mn、Ti)表达的修订碱度指数MBl7,与焦炭热态反应性之间线性相关性提高,其线性斜率为524.9,相关系数为0.658。
In this research, sixteen coke samples were collected from eleven coking enterprises in the country, and made some experiments to analyze the coke hot strength and Ash compositions in the cokes. The results of the re- search show that coke alkalinity coefficient MBI, which included five kinds of metal oxides, namely, Na,Mg,K,Ca and Fe, was related to the coke hot strength ~ The slope of the correlationline is 511.4, and the correlation coefficient is 0. 628. According to MBI revised, which included Na,Mg, K,Ca,Fe,Mn,Ti, the correlation related to the coke hot strength was improved, the slope is 524.9. and the correlation coet/icient is 0. 65lq.
