摘　　要：针状焦是20世纪70年代炭素材料中大力发展的一个优质品种,主要用于生产电炉炼钢用的高功率(HP)和超高功率(UHP)石墨电极和特种炭素制品。本文介绍了一种针状焦偏光显微定量分析方法,能直观地以数据形式来表述针状焦的微观结构,并找出针状焦的显微组织结构与热膨胀系数(te)的关系,可为深入研究针状焦性能及优化工艺参数提供理论依据。Needle coke is a high quality variety of carbon materials developed in the 1970s.lt is mainly used to produce high-power(HP)and ultra-high-power(UHP)graphite electrodes and special carbon products for electric steelmaking.This paper introduces a method for quantitative analysis of polarized light microscopy,which can visually describe the microstructure of needle coke in the form of data,and find out the relationship between the thermal expansion coefficient(cte)and the microstructure of needle coke.lt can provide a theoretical basis for in-depth study of needle coke performance and rational optimization of process parameters.
