Graphite electrodes are used in electric arc furnace (EAF) and ladle furnace (LF) for steel production, ferroalloy production, silicon metal production and smelting processes.
► Graphite electrodes structure drawing
Graphite electrode is composed of body and nipple, Used as conductive material on EAF (Electric Arc Furnace) and LF (Ladle Furnace) for steelmaking.
The graphite electrode is a carbon product prepared by calcining an amorphous carbon such as petroleum coke, needle coke or coal pitch through a graphitization furnace. It is a high temperature resistant graphite conductive material, also known as artificial graphite electrode.
►Graphite Electrodes Uses Specification
Graphite electrodes are the main heating element used in an electric arc furnace, a steelmaking process where scrap from old cars or appliances is melted to produce new steel.The electrodes are part of the furnace lid and are assembled into columns. Electricity then passes through the electrodes, forming an arc of intense heat that melts the scrap steel. Electrodes vary widely in size but can be up to 0.75 metres (2 and a half feet) in diameter and as much as 2.8 meters (9 feet) long. The largest weigh more than two metric tons.
