Professional Supplier 500mm dia .UHP graphite electrode

Product Description

Graphite electrode is mainly made of petroleum and needle  as raw materials and coal tar pitch as binder through calcination, proportioning, kneading, pressing, roasting, graphitization and machining. It is a conductor that releases electric energy in the form of electric arc to heat and melt the charge in the electric arc furnace. According to its quality index, it can be divided into ordinary power, high power and ultra-high power.

Our Advantage

Graphite electrode produced by our company has the advantages of low resistivity,high electrical conductivity and thermal conductivity,good oxidation resistance,good thermal shock resistance,high mechanical strength,easy to machine,etc.

Graphite electrode is widely used to smelt the steel,alloy steel and other metal or nonmetal material in electric arc furnace.

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.  eaf graphite electrodes

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.     electric arc furnace graphite electrodes

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.
