Problems solved by technology

[0002] During the roasting process of the prebaked aluminum electrolytic cell, due to the shape of the anode, the laying of coke particles, hanging poles, etc., the anode current is concentrated, the anode current distribution is too large, and the steel claws, anode explosion welding, and steel beams are red. Depolarization causes the electrolytic cell to fail to start normally. In severe cases, serial depolarization occurs during startup, and the startup is forced to stop, causing accidents and increasing the workload

Description

technical field [0001] The invention belongs to the technical field of electrolytic aluminum, in particular to a device for shunting anode current when an aluminum electrolytic cell is fired. Background technique [0002] During the roasting process of the prebaked aluminum electrolytic cell, due to the shape of the anode, the laying of coke particles, hanging poles, etc., the anode current is concentrated, the anode current distribution is too large, and the steel claws, anode explosion welding, and steel beams are red. Depolarization causes the electrolytic cell to fail to start normally. In serious cases, serial depolarization occurs during startup, and the startup is forced to stop, causing accidents and increasing the workload. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a device for shunting the anode current when the aluminum electrolytic cell is roasted...
