Graphite electrode is made of petroleum coke, needle coke, and bonding coal pitch. The production process is: calcining, dosing, mixing, forming, baking and impregnation, graphitization in a high temperature of over 3000°C, then precision machining. Graphite electrode acts 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 different grades, i.e. Regular Power( RP), High Power (HP), High Density (HD) and Ultra High Power (UHP) and different diameters and lengths, ranging from 100mm to 600mm.
Graphite electrodes are an important conductive material in the smelting industry with good electrical conductivity, thermal conductivity and high mechanical strength, good corrosion resistance under high temperature. Graphite electrodes are 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).
The Matech electrodes are sourced from one of the top Chinese producers with whom we’ve had a relationship of more than 20 years.
