why graphite electrode is used for steel melter

Why graphite is used as an electrode?

Why graphite is used as an electrode? The sole purpose of the graphite electrodes is to carry the electricity that melts scrap iron and steel. The DRI or direct-reduced iron is sometimes used in electric arc furnaces, which are the vast majority of steel furnaces. They are made from petroleum coke after it is mixed with coal tar pitch.

why graphite electrode is used for steel melter

Graphite electrodes are mainly used in electric furnace steelmaking. The graphite electrode for steel making accounts for about 70%~80% of the total amount of graphite electrode. In electric furnace steelmaking, a graphite electrode is used to introduce a current into the furnace, and a strong electric current generated arc-discharged by a gas

Arc Furnace Electrodes Coidan Graphite

Why use graphite arc furnace electrodes? Graphite electrodes are primarily used in electric arc furnaces for the steel production process. Large electrical currents are passed through the low conductivity electrodes, the power causes electric arcs between the tips of the electrodes and across the liquid steel, the arc is white hot circa 5000ºC.

Uses of Graphite Refractories, Batteries, Steel Making

Graphite is a stable form of naturally occurring carbon, also known as plumbago, blacklead or mineral carbon. Graphite is mostly used for refractory, battery, steel, expanded graphite, brake linings, foundry facings, and lubricants. Graphene, a naturally occurring ingredient in graphite, has unique physical properties and is one of the strongest known substances.

Green Graphite Electrodes Coidan Graphite

Why use Green Graphite Electrodes. Graphite manufacturing is highly energy intensive. Manufacturing one tonne of graphite requires 17MWhr of energy. This is equivalent to two households annual energy usage or 1.5 million charges of your mobile phone. Our reconditioning process uses less than 1% of the energy required to manufacture new electrodes.

Graphite Electrodes Rongxing Group

2021-8-27 Graphite electrode must be connected contacted closely and straightly. Use moment spanner for connecting electrode with suitable force. The gap between electrodes shall less than 0.4mm. The holding device must hold the electrode tightly, good contact and no arc. Otherwise, the connecting area will get red and oxidized and thin, leading breakage.
