Product Description

Prebaked Anode Manufacturer for Aluminium Plant Anode Butts

Product Description

The pre-baked anode is made of petroleum coke and pitch coke as aggregates and coal pitch as the binder, and is used as the anode material for the pre-baked aluminum electrolytic cell. This kind of carbon block has been roasted and has a stable geometric shape, so it is also called a pre-baked anode carbon block, which is also called a carbon anode for aluminum electrolysis. 
The pre-baked anode is one of the main raw materials for the production of electrolytic aluminum. Each production of 1 ton of electrolytic aluminum consumes about 0.5 ton of pre-baked anode. It is not only the conductive anode of the electrolytic cell, but also participates in the electrochemical reaction. It is called the pre-baked aluminum electrolytic cell. "Heart", its quality has a great impact on the economic benefits of electrolytic aluminum production, and it is an irreplaceable bulk material for the current aluminum smelting process.
