Artificial graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch. After calcining, burdening, kneading, forming, baking and pressure impregnation, it is graphitized in a high temperature of over 3000°C, and then treated with machining. Such of the products own characteristics with low resistivity, good electrical conductivity, low ash, even and compact structure, good anti oxidation and high mechanical strength.
