Product Description

Graphitized Cathode Block for Aluminium Electrolysis Smelter

Graphitized Cathode Block is a key lining and current-conducting material used in aluminium electrolysis cells. It is manufactured from high-quality carbon materials through forming, baking, and high-temperature graphitization, ensuring excellent electrical conductivity, thermal stability, and long service life under harsh operating conditions.

Applications

Graphitized cathode blocks are primarily used in aluminium electrolysis cells as lining and current-conducting components. They play a critical role in ensuring stable current distribution, reducing energy consumption, and extending the service life of the electrolytic cell.

These cathode blocks are suitable for use in:

√ Aluminium smelters and reduction cells
√ Electrolytic cells for primary aluminium production
√ Industrial furnaces requiring high electrical conductivity and thermal stability
√ Carbon lining systems exposed to molten aluminium and electrolyte

Features & Advantages

Key Features

√ High density and low electrical resistivity
