1、摘要真空抬包是电解铝冶炼过程中的一个重要设备，其主要功能是将电解槽中的电解铝液吸出并倒运至混合炉，是转运铝水的重要设备。真空抬包能够将电解槽中的电解铝液吸出并倒运到混合炉后浇铸成铝锭。该设备维护费用低、安全性高、工人劳动强度低等特点，一次可吸取几个电解槽内的铝液并直接送至混合炉，无需中途转浇包倒运，铝液热量损失小。该抬包采用正压喷射吸铝，改变了传统的负压直接吸铝，消除了负压吸铝对真空系统的危害，由于其可与电解槽共用一个气源，可省去整套真空系统，减少岗位配置，降低设备维护、检修费用，节约运行中的电费开
2、支。真空抬包采用茶壶式浇包的结构形式，铝液从包底浇出，熔渣被挡在包内，撇渣效果好。减速机是抬包的倾转机构，采用3级蜗轮蜗杆减速机。由于抬包容积的增大，自重及盛铝量均增大，抬包的倾转力矩增大，手动倾转费力、效率低而且不安全，该减速机在结构形式设计为手动与电动均可，正常操作为电动，手动为检修和突发事故时用，手动与电动的切换采用爪式离合器，切换迅速方便，安全可靠。该减速机电动为三级蜗轮蜗杆减速，手动为两级蜗轮蜗杆减速，减速比大。关键词：真空抬包、减速机、蜗轮、蜗杆31AbstractVacuumLadle
