Introduction:
High power (HP) graphite electrodes refer to the graphite electrode that allows the use of a current density of 18 ~ 25A / cm2.
Graphite electrode has good electrical properties and chemical stability. What’s more, graphite electrode has advantages of high mechanical strength, low impurity content and good vibration resistance. Graphite electrodes are good conductors of heat and electricity. Graphite electrode is widely used in steelmaking electric furnace, refining furnaces, production of ferroalloy, industrial silicon, yellow phosphorus, corundum , submerged arc furnaces and other smelting furnaces that produce high temperatures by electric arc.
According to the different of service power and electricity , using different raw materials and production technology, graphite electrodes can be divided into ordinary power (RP) graphite electrodes, high power (HP) graphite electrodes, ultra-high power (UHP) graphite electrodes.
Application:
High power (HP) graphite electrode is mainly used in high-power electric furnace and ladle furnace.
