摘要:
高纯铁是指纯度超过99.9%的铁。以高纯铁为原料开发的铁基材料具有比传统铁基材料更优异的性能，如更低的韧脆转变温度和再结晶温度、更好的抗腐蚀性能、更高的最大磁导率以及优良的导电性及低温热传导率，并因此在航空航天、电子信息、电力工业、军事工业等领域具有广阔的应用前景。虽然我国是全球最大的工业铁生产国和消费国，但却缺乏经济高效的高纯铁生产技术，导致所需高纯铁严重依赖进口。回顾并总结了当前世界上最具代表性的4种高纯铁制备方法，即直接还原熔分精炼方法、电解制备方法、火法提纯制备方法及湿法提纯+火法提纯的联合提纯制备方法，梳理并对比了我国与欧美日等发达国家的高纯铁制备技术研发历程，绘制了当前铁的纯度和市场价格之间的关系图，阐明了杂质元素对合金性能可能造成的负面影响，探讨了国内外高纯铁的未来发展趋势，并结合现状从制备技术的研发、行业标准的建立、应用市场的开拓及相关产业的发展等方面对我国高纯铁工业化制备进行了展望。
Abstract:
High purity iron is defined as iron that has purity more than 99.9%. High purity iron-based materials have higher performance than traditional iron-based materials, such as lower ductile-to-brittle transition temperature and recrystallization temperature, higher corrosion resistance, higher maximum permeability, excellent conductivity and low temperature thermal conductivity, thus showing promising applications in aerospace, electronics-information, electric power and military industries etc. However, China currently has to import most of the high purity iron used in its industry and scientific research institute, although China is the world’s largest producer and consumer of industrial iron, due to the lack of economic and efficient preparation technology of high purity iron. In this article, four typical methods for the preparation of high purity iron in the present world, direct reduction-smelting separation refining method, electrolysis method, pyrometallurgy method and hydrometallurgy-pyrometallurgy combined method, are reviewed and summarized. The development processes of researches in high purity iron preparation technology between China and developed countries such as Japan, Europe and the U.S. are compared. The relationship between the purity of iron and its current market price is illustrated. The possible negative effects of impurity elements on alloy properties are also indicated. The developing trend of high purity iron at home and abroad is discussed. At last, the industrial production of high purity iron in China is prospected from aspects of the research and development of preparation technology, the establishment of industrial standards, the development of application market and the development of related industries.
