Application of 250mm Graphite Electrode
 

Electric Arc Furnaces (EAF)
One of the primary applications of 250mm graphite electrodes is in electric arc furnaces (EAF) for steel production. The use of graphite electrodes in EAFs allows for precise control of the melting process and ensures efficient energy transfer, resulting in high-quality steel production.

 

Ladle Furnaces
Ladle furnaces are another important application area for 250mm graphite electrodes. The use of graphite electrodes in ladle furnaces ensures precise control over the refining process, leading to the production of high-quality, clean steel.

 

Aluminum Industry
In the aluminum industry, 250mm graphite electrodes are used to produce primary aluminum via the Hall-Héroult process. The electrodes are immersed in the electrolytic cell and are responsible for passing the electrical current through the alumina to facilitate the electrolysis process, resulting in the production of pure aluminum.

 

Non-Ferrous Metals Production
250mm graphite electrodes are also used in the smelting and refining of copper and other non-ferrous metals, where they play a critical role in providing the necessary heat and electrical conductivity for the production process.

 

Chemical and Industrial Applications
250mm graphite electrodes find applications in various chemical and industrial processes. They are used in electric heating elements for high-temperature furnaces, resistance heating, and other thermal processing applications.

 

 
 
High Purity Raw Materials for Graphite Electrodes
250mm Graphite Electrode for Arc Furnaces

Petroleum Coke/Carbon Carrier Material

You will need carbon carrier because it serves as the main source of carbon in the graphite electrodes manufacturing process.In graphite electrode production, it provides high electrical conductivity and strength in the end product.

250mm Graphite Electrode for Steel Making

Pitch Binder

The binder is ideally petroleum pitch or coal tar pitch, which serves as an agent for bonding. Pitch binders provide you with the needed plasticity to ensure raw materials are molded into shape.

 

Uhp 250mm Graphite Electrode

Needle Coke

Needle cokes are a unique type of petroleum coke. It is a vital ingredient in producing ultra-high power (UHP) graphite electrodes.
