RP Graphite Electrode Technical Specification
The technical properties of the high power and Ultra high power graphite electrodes are better than those of regular power graphite electrodes, such as lower resistivity, higher bulk density, higher mechanical strength, and lower linear expansion coefficient, excellent oxidation resistance and so on.Regular power graphite electrodes are used for ferroalloy production, silicon metal production and smelting processes.
