Specifications

Graphite Electrodes 
Graphite electrode is made of petroleum coke, needle coke, and bonding coal pitch. Its production process is: calcining, dosing, mixing, forming, baking and impregnation, graphitization in a high temperature of over 3000°C, then precision machining. 
Graphite electrode is acting as a conductive body which release heat in the form of arc for heating and melting steel in the furnace. According to the application, it can be divided into regular power(RP), high power(HP) and ultra high power(UHP). 
Graphite electrode is an important conductive material in smelting industry with good electrical conductivity, thermal conductivity and high mechanical strength, good corrosion resistance under high temperature. Graphite electrode is widely used in EAF, LRF, submerged arc furnace(producing ferroalloy, pure silicon, yellow phosphorus, calcium carbide etc), resistance furnace (such as the graphitization furnace, glass melting furnace and silicon carbide furnace etc). 

XINHONG carbon advantage: 
Strictly control of raw material ensures it is from the best origin; 
Advanced production technology & facilities &experienced workers; 
Strict quality tracing system to ensure each GE excels buyer needs; 
Technical assistance & after service are available whenever needed; 
Sufficient stock in factory to ensure competitive price&fast delivery;
