Electric arc furnace graphite electrodes

By:Win Dec 24, 2020
Electric arc furnace graphite electrodes are conductive material in electric arc furnace (EAF) steelmaking, as the melting point of graphite is around 3900℃, and scrap steel is 1700℃, while the temperature in EAF is above 3000℃.

The main raw materials of Electric arc furnace graphite electrodes are petrol coke and needle coke, pitch impregnation, through more than ten processes and graphitization of 2800~3000 ℃, can reach the technical data standard of using in EAF.

The consumption of graphite electrodes is related to the use of EAF steelmaking and the quality of graphite electrodes. Usually, 2 kilograms of graphite electrodes are consumed to melt one ton of steel, which accounts for a small proportion of steelmaking costs. Under all the same conditions, the larger the discharge current during steel making, the more consumption of the graphite electrode.
