Graphite electrodes are large cylindrical structures made up of petroleum needle coke and coal tar pitch. They conduct electrical energy from the power source and convert it into heat which is used to melt scrap metal. Since graphite has high thermal conductivity and low electrical resistance, these electrodes can generate heat up to the temperature of degree Celsius. They are primarily used in Electric Arc Furnaces (EAF) and Blast Oxygen Furnaces (BOF) for steelmaking and smelting ferrous alloys. These electrodes help in the manufacturing of high-quality products that can withstand high heat dissipation have high electrical conductivity and exhibit exceptional mechanical strength.
The rising demand for graphite electrodes in steel-oriented sectors such as construction, automotive, infrastructure, and aerospace and defense are the key factor driving the market. The increasing requirement of anti-corrosive products for oil and petroleum wells and pipelines in the oil and gas sector has further enhanced the use of EAF, and subsequently catalyzed the demand for these electrodes. Additionally, the increasing requirement for Ultra-High Power (UHP) graphite electrodes is another market trend that is projected to drive the market. UHP has a higher thermal and electrical conductivity and can swiftly melt scrap to manufacture steel. It is therefore highly preferred by steel manufacturers, and its demand is expected to grow substantially in the coming years.

DESCRIPTION
UHP graphite electrode is used for the recycling of steel in the electric arc furnace industry. Its main ingredient is high-value needle coke which is made from either petroleum or coal tar. Graphite electrodes are finished with a cylinder shape and machined with threaded areas at each end. In this way, the graphite electrodes can be assembled into an electrode column using electrode nipple.
In order to meet the requirement of higher work efficiency and lower total cost, large capacity ultra-high power arc furnaces are becoming more and more popular. Because of this, UHP graphite electrodes with diameters of over 500 mm will dominate market.

Guidance of Using
Being hard and brittle ,artificialgraphite electrode shall be specially handled.Proper operationg may reduce the consumption and cost.
1
. Professional tools should be used for hoisting graphite electrodes. It is strictly forbidden to use a crowbar to prevent impact damage during handling.
2.
Graphite electrodes are prohibited from rain, snow and water, and should be kept dry. If it is found to be damp, it should be dried before use, the temperature should not exceed 100 ºC, and the drying time should not be less than 48h.
3.
Do not stack near debris such as clay, slag, etc., so as not to pollute the surface of the graphite electrode and affect the conductive effect.
4.
Before the graphite electrode is connected, carefully check whether the electrode connector hole is intact, whether the connector thread is damaged, and whether the connector bolt is lost. When the electrode is lifted, the electrode connector thread of the ground terminal should be prevented from being damaged.
5.
Dust and debris in the joints and joint holes should be blown dry with compressed air.
6.
Graphite electrodes must be tightly connected, and no tilt is allowed during connection. Torque wrenches should be used to prevent excessive force or too small, and the gap is not greater than 0.4mm.
7.
The electrode holder should be clamped, not loose and in good contact, and no arc should be generated. Otherwise, the connection will be reddish, oxidized, thinned and broken.
8.
If the electrode is lifted with a metal lifting plug, the thread in the joint hole must not be damaged. After lifting, the lifting plug should be unscrewed to prevent dust and debris from falling into the joint hole.
9.
When the electrode lifting device of the electric furnace is running, it should be kept stable. After the furnace cover is repaired, check whether the furnace cover is positioned correctly. During smelting, refractory materials are used to close the furnace lid to prevent the oxidation of the upper electrode of the flame in the furnace.
10.
The holder should be clamped outside the safety wire of the electrode connector hole area.
11.
When distributing the molten pool, the big piece is at the bottom and the small piece is at the top. Do not place the charge with poor conductivity on the top. During melting, the unmelted charge should be handled in time to prevent the collapsed material from breaking the electrode.
