一、前言 75型电动机械打壳机是适应中小型铝厂电解生产时,打破电解质结壳的设备。 目前一些小铝厂,打壳作业仍然是采用手工劳动,劳动强度大,工作效率低。浙江衢州铝厂几年的生产实践证明,电动打壳机可以代替笨重的手工劳动。 为了使75型电动机械打壳机适应更多的中小铝厂,本文着重介绍这种打壳机的构造及应用。 I. INTRODUCTION The 75-type electric machine shell breaker is a device that breaks the electrolyte crust when it is adapted to the electrolytic production of small and medium aluminum smelters. At present, some small aluminum plants, shell operations are still using manual labor, labor-intensive, low efficiency. Zhejiang Quzhou aluminum plant a few years of production practice has proved that electric shell-breaking machine can replace bulky manual labor. In order to adapt 75 type electric mechanical shell-forming machine to more medium and small aluminum plants, this article focuses on the construction and application of this type of shell-forming machine.
