第I条 Abstract

Graduate design of the entire contents is the design of a large-scale absorption of aluminum vacuum ladle of the main design features and technical difficulties. With electrolysis technical transformation of the expansion project completed ,To solve molten aluminum suction operating inefficiencies, molten aluminum heat loss big issue ,we need to develop bulk density of 4 -6 tons without interim Ladle unlucky vacuum ladle.

With the domestic large prebaked electrolyzer successfully developed, the current was gradually increased to 160 KA, 200KA. 280KA, 320KA, electrolyzer resulted in a significant increase in production of aluminum, aluminum vacuum suction small ladle has been unable to meet production needs.

Sealing performance through the use of good, strong ability to prevent deformation of the ladle structure, High Life package and suction tubes lining and reasonably ascertain the location of shaft, so we will be able to achieve more satisfactory results.

Papers used by the design of large aluminum vacuum suction Ladle institutions is conducive not only to better meet the needs of production, further improve the production efficiency and greatly enhance the production progress and hence involves the production proceeds. It as a production of intermediate process for the production of essential progress is essential to the production part.

Key words: Ladle structure,vacuum, jet

第II条  摘要

    毕业设计的全部内容设计为大型吸铝真空抬包设计的主要特点与技术难点。随着电解技改扩建项目的完成 , 为解决铝液抽吸运转效率低下、铝液热量损失大的问题,需要研发容重为4-6 吨无需中转浇包倒运的真空抬包。

    随着国内一些大型预焙电解槽的研发成功, 电流已陆续提高至160KA、200KA、280KA、320KA,电解槽产铝量大增,小型吸铝真空抬包已不能满足生产的需要。

    通过采用密封性能好、防变形能力强的抬包结构,使用寿命高的包衬和吸铝管以及合理地确定转轴的位置,这样就能达到较为满意的效果。

    采用论文中所设计的大型吸铝真空抬包机构不仅有利于更好地满足生产的需求,进一步提高产品的生产效率,大大地提高生产进度以及由此而牵扯到的生产收益问题。它做为一个生产的中间过程,对于生产的进度来说至关重要,是生产所必不可少的一部分。
