Abstract

A manufacturing method of a pre-baking aluminium cell shell comprises the steps of short side plate structure manufacturing of the cell shell, long side plate structure manufacturing, bottom plate manufacturing and cell shell assembling. The manufacturing process of the pre-baking aluminium cell shell is more convenient and fast due to a mould for the short side plate structure manufacturing, a mould for the long side plate structure manufacturing and a mould for bottom plate turning.

Description

[0001] Field

[0002] The invention relates to the field of manufacturing aluminum electrolytic cells, in particular to a method for manufacturing a prebaked aluminum electrolytic cell shell. technical background

[0003] Aluminum electrolytic cell is the main equipment for aluminum smelting production, mainly including tank shell, cradle frame, tank cover, cathode, anode, conductive system, etc. Among them, the tank shell is the main place for electrolytic reaction, which is a square pool-like structure surrounded by a bottom plate, two side wall plates, and two end plates. Since the reaction conditions of aluminum electrolysis are very harsh, in order to ensure that the entire aluminum electrolysis process can be carried out safely and effectively, it is necessary for the electrolytic cell shell to maintain as little deformation and low temperature as possible under the combined influence of complex high temperature environment and various forces Crack rate.
