What are Graphite Electrodes and Needle Coke?​

 

 

​Graphite electrodes​​ and ​​needle coke​​ are closely related in production. ​​Needle coke​​ is a high-quality, needle-like form of petroleum coke that is the ​​primary raw material​​ used to manufacture ​​high-power and ultra-high-power graphite electrodes​​.

 

​Needle Coke Characteristics:​

 

Low coefficient of thermal expansion

 

High graphitizability

 

Low sulfur and metal impurity content

 

These properties make needle coke ideal for producing graphite electrodes that can withstand extreme conditions in EAF steelmaking and other high-power applications. During graphite electrode manufacturing, needle coke is mixed with coal tar pitch, formed, baked, and then graphitized to achieve the final conductive and heat-resistant product.
