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 industrial indexes, technical indexes, coal and rock indexes of the quality of coking coal in Indonesia, Mongolia, the United States and other countries and the coke microstructure of single species of coal were studied. It was pointed out that the procurement department should not only rely on the common domestic industries Indicators and indicators of coal and rock, but also according to the rheology, expansibility and single-coke into the microscopic structure of coal and other aspects to determine the quality of coal in order to determine a reasonable price.
