In recent years, due to the continuous innovation of steel making furnace technology, the graphite electrode for steel making has been put forward higher requirements. High power and ultra-high power EAF steel making process can reduce smelting time by 56%, save more than 22% of electricity per ton of steel, and increase output by 1.3 times. In order to meet the needs of this steel making process, high power and ultra-high power graphite electrodes are produced.
The graphite electrode has the following characteristics：
The specific resistance is low, which can lead in 25% - 40% higher current than ordinary graphite electrode;
The linear expansion coefficient is small and the quick cooling and heating resistance is good;
The mechanical strength is higher than that of graphite electrode;
The oxygen loss is small, and the unit consumption of electrode in steel making is about 1 times lower than that of ordinary graphite electrode.
