Graphite Electrode - an overview | ScienceDirect Topics
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.

HistoryConstructionEnergy DensityOperationAdvantages For SteelmakingIssuesOther Electric Arc FurnacesCooling MethodsPlasma Arc FurnaceVacuum Arc RemeltingIn the 19th century, a number of men had employed an electric arc to melt iron. Sir Humphry Davy conducted an experimental demonstration in 1810; welding was investigated by Pepys in 1815; Pinchon attempted to create an electrothermic furnace in 1853; and, in 1878–79, Sir William Siemens took out patentsfor electric furnaces of the arc type. The first successful and operational furnace was invented by James Burgess …en.wikipedia.org でさらに表示History· Construction· Energy density· Operation· Advantages for steelmaking他の人は以下も質問していますHow are graphite electrodes used in EAF baths?How are graphite electrodes used in EAF baths?Graphite electrodes serve to transfer the electrical energy from the power supply to the steel melt in the EAF bath.

Introduction to Understanding Electric Arc FurnacesHistory of Electric Arc FurnacesFurnace Installation Equipment DescriptionElectric Arc Furnace Working Principle and OperationHealth Impacts Around Electric Arc FurnacesElectric arc furnaces are a firebrick-lined U-shaped vertical vessel in which scrap steel is melted by an electric arc instead of the usual fossil fuel. They are sometimes used as mini-steel producers, manufacturing steel products such as structural steel rods and bars. Many years ago I was engineer in an aluminum smelter here in the Highlands of Scotland, and we had an EAF which used to scare the life out of me.
