Abstract

The invention discloses a mechanical anode steel claw structure for a prebaking aluminum cell. The mechanical anode steel claw structure comprises a mechanical steel claw base plate (9). An anode carbon block connection device is arranged below the mechanical steel claw base plate. An anode aluminum conducting rod (2) is connected to the portion above the mechanical steel claw base plate (9). The mechanical anode steel claw structure has the advantages that carbon blocks are rapidly replaced, time and labor are saved, heat energy is saved, contact resistance and voltage drop of a steel claw and a carbon block are lowered, and the number of anode carbon block sets is decreased.

Description

technical field

[0001] The invention relates to an aluminum electrolytic anode steel claw, in particular to a mechanical anode steel claw structure for a prebaked aluminum electrolytic cell. Background technique

[0002] In the modern electrolytic aluminum industry, prebaked anodes are used to produce electrolytic aluminum. The prebaked anode is generally a cuboid with a stable geometric shape. It uses stone tar and pitch coke as the aggregate and coal tar pitch as the binder. It has different sizes according to the size of the electrolytic cell current and the process. Its current density Generally at 0.68-0.9A / cm 2 Within the range, the service life of each carbon block is generally 23-30 days.

[0003] In the existing prebaked anode electrolytic aluminum production, the anode steel claws and the anode carbon block are all connected by casting of phosphorus pig iron, and there are 2-4 diameters of 160-180mm on the upper surface of the prebaked anode carbon block in the c...
