摘　　要：煤沥青流变性能对炭材料生产影响极大,煤沥青流变性能的合适调节及相应工艺参数的优选对于提高炭材料质量有着重要的作用。文章讨论了混捏、成型、焙烧和浸渍过程中影响煤沥青流变性能的因素,分析了工艺参数变化对煤沥青流变性能的调节作用,提出了改善煤沥青流变性能的措施。The rheological behavior of coal- tar pitches has a very large effect on the manufacture of carbon materials, Suitable regulation of rheological behavior and optimization of process parameters play an important role in the upgrade of carbon materials. Some factors deciding the rheological behavior of coal- tar pitches in the kneading, molding, baking and impregnation processes are discussed. The roles of process parameters in the regulation of rheological behavior of coal- tar pitches are analyzed. Some measures modifying the regulation of rheological behavior of coal-tar pitches are pointed out.
