Introduction to Graphite Electrodes
Graphite electrodes are essential components in the steel - making industry, especially in electric arc furnaces (EAF). They are made from high - quality petroleum coke and needle coke, which are baked and graphitized at high temperatures. Graphite electrodes conduct electricity to generate the high - temperature arc needed to melt scrap steel and other raw materials. Their high thermal conductivity, electrical conductivity, and resistance to thermal shock make them ideal for this high - energy process. The quality of graphite electrodes can significantly affect the efficiency and cost of steel production.
