国内外改质沥青生产的现状及其发展

煤焦油沥青是炼铝及碳素工业的重要原料之一，它地质量如何直接影响到制品的技术经济指标。近年来，随着科学技术的发展，煤焦油沥青重整改质技术引起重视。目前已有许多国家已生产出改质沥青来满足制取电炉炼钢超高功率电极以及制品铝电解板的要求证同国内对此也开始进行研制工作。介绍了国内外改质沥青生产的现状及发展，并提出了参考建议。

Present Status and Development at Home and Abroad of Modified Pitch Production

Coal tar pitch is a necessary raw material for smelting Aluminium and car-bonizing process, its qualities direct affect technical and economical indexes of products. Re-cently, with the development of science and technology the reforming and modifying pro-cesses of pitch have engaged a good deal of attention, in many countries modified pitch is produced to satisfy the requirements of manufacturing electrodes for UHP EAF and alumini-um eletrolytic plate. In China, this subject is being studied. This article introduces the pre-sent status and development at home and abroad of production of modified pitch, and gives some reference proposals.
