【摘要】 我国铝工业正遭遇氧化铝资源和电解铝能源危机,铝的再生熔炼和精炼的研究将为铝工业循环经济和可持续发展提供技术储备。本文综述了再生铝熔体净化熔剂处理的理论基础、技术发展现状、提高净化效果的主要途径,以及再生铝熔体熔剂净化过程中存在的问题。提出将结构测试技术与计算机模拟和理论计算方法相结合,对再生铝熔体净化过程相关的物理化学基础科学问题进行深入研究,针对各种杂质元素的特殊性设计高活性精炼剂,通过选择性除杂实现铝熔体深度净化,是再生铝精炼熔剂的重要研究内容。更多还原

【Abstract】 With the crisis of mineral sours and energy sour becoming more and more serious in our country, recycle of second melts become a serious topic. New techniques for purification of recycled aluminum melting are needed eagerly. A key procedure is fining of aluminum melting by fluxes. The techniques and effects of aluminum melting body fluxes were summarized and analyzed. The insufficiencies of application and investigation of the fluxes were also pointed out. Then the developing trends of aluminum fluxes were put forward. Investigation of fluxes for fining recycled aluminum melting will provide important fundamental for reuse of second-aluminum resource.更多还原
