550mm Ultra High Power Graphite Electrodes Needle Coke Corrosion Resistance

The 550mm Graphite Electrodes are produced with advanced needle coke, and the graphitization heat treatment is carried out in the internal series graphitization furnace. The graphitization temperature is up to 2800 ~ 3000°C, so the resistivity is lower, allowing greater current density, smaller thermal expansion coefficient, and excellent thermal shock resistance.

In addition, they have the advantages of compact structure, good electrical and thermal conductivity, strong oxidation resistance, corrosion resistance, low resistivity, and high current load resistance. They can be widely used for electric furnace steel making, industrial silicon, quartz glass, corundum and other industries.

They receive an excellent reputation among clients all over the world due to high performance and high cost effective.
