Graphite electrode Production Description. Graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc.
Graphite electrode (GE), which is primarily used in the steel production via Electronic Arc Furnace (EAF) saw a huge surge in its prices in the past 6-8 months. This was due to a sudden and unforeseen deviation in the demand-supply dynamics.
Tightness in Chinese electrode and needle coke supply -- the primary raw material for graphite electrodes used in steelmaking-- has curbed the amount of material available, and China's own electrode consumption is rising as electric arc furnaces are melting more scrap rather than charging hot metal, sources said.

Graphite electrode is an essential material used in the electric-arc furnace for manufacturing of steel, for its outstanding electrical conductivity, and incredible anti-thermal shock capability. The growth of global graphite electrode market is primarily driven by the growing demand for steel owing to rapid industrialization, and urbanization globally.
How to size an electrode. ... Select an electrode that is closest to 60% of the drill diameter; ... Graphite Electrodes. When removing large bolts .750″ to 19 mm and up use Graphite Electrodes for optimum performance and value. Graphite Electrodes only work on metal disintegrators with 20KVA or DC power supply.
Steel prices are already feeling the impact of electrode shortages, but so far only in select countries. European prices jumped €30 to €50 in September, and remain elevated. Electrodes were not the sole reason for the hike, but they are probably the most referenced cause when sellers negotiate with buyers for 2018 contracts.
Chronoamperometries with stainless steel and graphite electrodes. To distinguish between electrode material or electrode potential to tip the balance towards anode or cathode properties, two experiments were conducted with stainless steel and graphite electrodes polarized …
Electrode wear is a constant concern because excessive wear results in adding electrodes or redressing electrodes more often. Graphite is able to achieve electrode wear of less than 1 percent in relation to the depth of cut at machine parameters much more aggressive than copper electrodes.
