Introduction to graphite electrodes

The main raw material for graphite electrode production is petroleum coke. A small amount of pitch coke can be added to ordinary power graphite electrodes. The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required when producing high-power or ultra-high-power graphite electrodes. The main raw material for aluminum anode production is petroleum coke, and the sulfur content is controlled to be not more than 1.5% to 2%. Petroleum coke and pitch coke should meet the relevant national quality standards.
