摘　　要：利用元素分析、红外光谱、激光粒度仪、原子发射光谱仪等分析手段对攀钢中温煤沥青的原生QI进行了结构组成分析。结果表明,原生QI粒径90%以上小于2μm,为无定型的微晶乱堆结构,其灰分质量分数达到5.8%。元素分析和红外光谱分析表明,QI有机成分主要为高度缩合的炭黑状物质,金属分析表明无机成分主要由耐火材料粉屑和铁件的氧化物构成。这为原生QI的脱除提供了科学依据。In this paper, the characters of primary QI in coal-tar pitch are analyzed using elemental analysis,FTIR, laser granularity analysis and ICP-AES etc. The results show that more than 90% QI particles are less than 2 μm in diameter, which are unformed and huddled crystals. The ash content of QI reaches 5.8%. The elemental analysis and FTIR show that the organic components are mainly the highly condensed charcoal compounds and the inorganic components are mainly the scrapings of the refractory materials and some oxides of iron parts.
