Artificial graphite electrodes are made from high-quality materials like petroleum coke, needle coke, and coal pitch after a series of steps including calcining, burdening, kneading, forming, baking ,pressure impregnation and graphitization in a high temperature of over 3000°C.Such products have the characteristics of low resistivity, good electrical conductivity, low ash, even and compact structure, good antioxidation and high mechanical strength.
