摘要
对印尼、蒙古、美国等国炼焦煤质量的工业指标、工艺指标、煤岩指标、单种煤焦炭显微结构进行研究,提出采购部门在引进新增炼焦煤资源时,不能仅依据国内常用工业指标和煤岩指标,还得根据流变性、膨胀性及其单种煤成焦显微结构等多方面来判定煤质,从而确定合理的性价比。
The quality of the coking coal imported from Indonesia,Mongolia and USA involving the industrial index,process index,petrology index and the micro structure of every single coking coal is investigated and thereupon proposal for the purchasing department is advanced that in the process of introducing coking coal resources determination of the coking coal quality can not only be based on the industrial index and petrology index of the coal traditionally adopted at home and the other indexes such as the fluxision,expansion and the micro structure of the single coking coal should be used to determined the quality of the coal so as to ascertain a reasonable cost performance.
