1、I 320kA 预焙槽铝电解车间及阴极结构设计 摘 要 中国铝电解技术自 70 年代末引进 160KA 预焙槽技术之后有所发展，从 消化国外技术开始，揭开了中国现代铝电解技术发展的序幕。从此以铝电解 槽为核心，对其各个方面进行了广泛而深入的研究。九十年代以来，在基础 理论、 大型铝电解槽开发以及工程应用取得了一系列成果， 开发成功了 280、 320KA 级的大型电解槽技术，使铝工业的技术进步令人注目。大容量电解槽 的开发，使中国铝电解技术总体上达到了国际先进水平，电解铝工业的面貌 发生了根本的改变。现如今，320kA 级的大容量、高效节能型预焙铝电解槽 已成为当今世界电解铝工业先进工艺装备技

2、术的主流。 本文主要介绍了 320kA 铝电解车间设计的相关背景和必要的计算,主要 是一些相关的技术经济指标，物料平衡，能量平衡等，设计铝电解车间和异 型结构阴极。本设计根据当地的情况进行设计，希望能对大型预焙槽炼铝车 间的设计提供一定的参考意义。 关键词：320kA，物料平衡，能量平衡，铝电解槽，阴极结构，电解车间 II The Design of 320kA Pre-baked Anode Aluminum Reduction Workshop and Cathode Structure ABSTRACT Chinese aluminium electrolytic technology

3、has developed since the introduction of the 160kA pre-baked anode technology in late 1970s. From the beginning of digesting the foreign technology, it opened the prelude to the development of modern aluminium electrolytic. Since then, people go on the study of all aspects of aluminium reduction cell

4、 extensively and in-depthly. A series of achievement has been made in basic theory, large-scale aluminium reduction cell, engineering applications and the successful development of the 280, 320 kA-class large-scale electrolyzer technology. It makes the aluminium industrys technological progress impr

5、essive. Development of large-capacity electrolyzer makes the Chinese aluminium electrolytic technology reached the international advanced level on the overall. The aluminum industry has undergone fundamental changes. Now 320kA level high-capacity, highly efficient energy-saving Pre-baked aluminium r

6、eduction cellhas been become mainstream of todays world aluminium industry advanced technology and equipment. This paper introduces the 320kA aluminum electrolytic plant design background and the necessary calculations. Its subject is to put forward the views for the applications，hoping to give those researchers some useful reference.
