Graphite Electrodes
Description:
Graphite electrodes serve to transfer the electrical energy from the power supply to the steel melt in the EAF bath. They are typically made using premium petroleum needle coke, coal tar pitch, and some additives.
Graphite electrodes consumption varies between 1.8 and 9.9 kg/t of liquid steel depending on the process characteristics and electrode quality. The electrode consumption in Germany in 2010 was approximately 1.1 kg per ton as a result of the reduction of time between the taps to 40 min and consequently the lower electricity consumption (345 kWh/t). Graphite electrodes are classified as regular grade or premium grade on the basis of their physical properties.
