Primary Aluminium
Anode carbon block refers to the carbon block produced with petroleum coke and pitch coke as aggregate and coal pitch as the binder. It is used as a pre-baked aluminum electrolytic cell as anode material.
Primary Aluminium
The carbon sidewall block refers to a carbon block made of high-quality anthracite, coke, graphite, and other raw materials. It is built on the side of the electrolytic cell.
Primary Aluminium
The cathode carbon block refers to a carbon block made of high-quality anthracite, coke, graphite, and other raw materials. It is built on the bottom of the electrolytic cell and used as the cathode of the aluminum electrolytic cell.
