FAQs

What is pre-baked anode carbon block?

Pre-baked anode is a kind of carbon block produced by proportioning, kneading, forming and roasting with calcined petroleum coke and pitch coke as aggregate and coal pitch as binder. This kind of carbon block is called pre-baked anode carbon block because it has a stable geometric shape after roasting before being used in electrolytic cell, and it is also called carbon anode for aluminum electrolysis customarily. Pre-baked anode is used as the anode material of pre-baked aluminum smelting cell.

Pre-baked anode used in aluminum electrolysis smelting is one of the main materials in aluminum smelting production, which consumes about 500 kilograms of anode carbon block per ton of aluminum smelting production. It is not only the conductive anode of aluminum smelting cell, but also participates in electrochemical reaction, and is called the “heart” of aluminum electrolysis smelting cell. Its quality has great influence on many economic indexes and benefits of aluminum electrolysis smelting production, and it is an irreplaceable consumable material in current aluminum smelting process.

Pre-baked anode carbon block is the 2nd important raw material for aluminum smelting except alumina.

The aluminum electrolysis cell with prebaked anode carbon block as anode is called prebaked anode electrolysis cell, or prebaked cell for short.

The anode block is generally cuboid, and there are 2~4 round grooves with a diameter of 160~180mm and a depth of 80~110mm on its upper surface in the conductive direction, commonly known as the carbon bowl. When the anode is assembled, the carbon bowl is used to place the anode claw head, and the anode guide rod and the anode block are connected into a whole by pouring phosphorus pig iron to form an anode carbon block group. The anode block has different sizes according to the current of the electrolytic cell and the process, but the current density through it is generally 0.68~0.95A/cm2, and the service period is 26~32 days.

Pre-baked carbon anode is easy to operate, easy to realize mechanization and automation, and the anode voltage drop is lower than that of self-baked anode, which eliminates the asphalt smoke in the electrolysis process and is beneficial to the development of electrolytic cell towards large capacity. Therefore, the new-built aluminum smelting plants all adopt pre-baked carbon anode.
