Product details
Graphite Electrodes find application in manufacture of Steel and other non-ferrous metals through the Electric Arc Furnace and the Laddle Furnace routes. It is used as a consumable for conducting high current at low voltage which is necessary for melting and / or alloying processes.
Electric arc furnaces are cheaper to build than traditional blast furnaces, which make steel from iron ore and are fuelled by coking coal. But the cost of steelmaking is higher since they use steel scrap and powered by electricity.
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.
It takes up to 3 kg (6.6 lb) of graphite electrodes to produce one tonne of steel.
The tip of the electrode will reach 3,000 degrees Celsius, half the temperature of the sun
