Abstract

The invention discloses an aluminum cell lining struction, provided with cathode block, cell shell, which is characterized in masoning impervious brick skin, insulating brick skin and firebrick skin from upper to lower besides the floors of the cathode block and the cell shell separately, a latus breaker locating in the coupling part of the side face of these brick skins and the cell shell, masoning a breaker and a latus impervious brick between the cathode block and the inner side of the cell shell, and a side mass of silicon nitride associated with charring silicon around the upper part inside the cell shell, besides the side mass and cathode block covered with charcoal paste layer. The invention is of higher groove depth, which is available to self-extinguishing effect of cells, and of extend radiating area; a plurality of breakers for absorbing expansive power arisen from carbon blocks; good thermal balance in the industrial process of the cell, which can be prolonged cell life to 2000 days from 1500 days.

Description

Technical field

[0001] The invention relates to an inner lining structure of an aluminum electrolytic cell. Background technique

[0002] The aluminum electrolytic cell lining is an important part of the electrolytic cell, which is directly related to the heat balance and service life of the electrolytic cell. Chinese patent, patent No. ZL00223634.6 discloses a patent named aluminum electrolytic cell lining structure, the applicant is Guiyang Aluminum Magnesium Design and Research Institute, and it is classified as prior art below. At present, the anti-seepage layer under the cathode carbon block group of the electrolytic cell lining structure in the prior art mostly adopts powdery dry anti-seepage material, which has good electrolyte permeability resistance, but it needs a special machine for high-frequency vibration during construction. Compaction; light or heavy castables are used around the cathode carbon block, which contains a certain amount of water. After the water ...
