Attrition rate

The rate at which UHP graphite electrodes are consumed in an EAF depends on the steelmaking or other raw materials used, the grades of steel being produced, and the amount of supplemental (chemical) energy used. EAFs typically consume electrodes at a rate of around 2kg per tonne of steel produced, with some specialty steel applications consuming at a slightly higher rate.

Application

The application of ultra-high power UHP graphite electrodes in steelmaking is significant, particularly in electric arc furnaces (EAFs).

Graphite electrodes are mainly used in electric arc furnace steelmaking, the working principle of graphite electrodes in steel refining involves generating high temperatures through an electric arc, melting the metal at the furnace’s base, and facilitating critical chemical reactions such as decarburization and alloying to produce high-quality steel.
