【摘要】 介绍了"炼焦煤炭化关联性评价方法"和"焦炭综合热性能评价方法",分别用于检测单种炼焦煤及配合煤在炭化过程中挥发分析出、胶质层生成和膨胀压力之间的关联性;检测焦炭溶损反应开始温度、溶损速率、等溶损率(25%)反应后强度及其对温度的依赖、反应后焦炭热缩聚指数和热强度。这两种方法可以进一步深入辨识炼焦煤和焦炭的性能,建立新的质量评价方法。更多还原

【Abstract】 The evaluation methods for "the related properties during carbonization of coking coal" and "the comprehensive thermal performance of coke" were developed. The former one was used to measure the relevance between the volatile matter escaping, plastic layer forming, and swelling pressure during single and blending coking coal carbonization process; the latter one was used to detect the initial temperature of coke reaction, the average coke reaction rate and the coke strength after reaction at the coke weight loss up to 25%, the dependence of the coke strength after reaction on the reaction temperature, the coke polycondensation index and coke strength after polycondensation for the coke weight loss up to 25%. These two methods can be used to further identify the performances of coking coal and coke, and establish some new evaluation methods of coking coal and coke quality.更多还原
