UHP/HP/RP Dia 300-700mm Graphite Electrode With Nipple for Eaf
Graphite electrode is a high-temperature graphite conductive material composed of petroleum coke and tar as fillers, and coal tar as binder. Graphite electrodes have the characteristics of low resistance, good conductivity and thermal conductivity, high oxidation resistance and thermal shock resistance, and high mechanical strength.Graphite electrodes can be divided into ordinary power graphite electrodes, high-power graphite electrodes, and ultra-high power graphite electrodes.
The diameter of graphite electrodes is 75mm-800mm. We produce graphite electrodes and electrode nipples. We can produce various specifications of products according to customer requirements. Our advantages: 1. Made in China quality, 2. Factory direct sales, 3. Fast delivery, 4. Competitive prices

* High density, high temperature resistance, high mechanical strength and strong chemical stability.
* The surface can be treated with anti-oxidation.
* Corrosion resistance, strong acid and alkali resistance.
* Excellent thermal shock resistance, electrical conductivity and thermal conductivity.
* Strong wear resistance and lubricating performance.
* Long service life.
Application:
1.For arc furnaces of electric arc furnaces. Graphite electrodes are most often used in a coal-smelting electric furnace.
2.For a closed arc
3.For a resistor furnace
4.For the production of graphite shaped products. The graphite electrode blank is also used for processing in various crucibles,shapes, boats and heating elements and other graphite products. For example, in the quartz glass industry, for each production of 1 ton of an electric melting tube, a graphite electrode 10 m is required, for each quartz brick of 1 ton it is necessary to consume 100 kg of graphite electrode.
Properties:
1.Anti-oxidation treatment for longevity.
2.High-purity,high-density,strong chemical stability.
3.High machining accuracy,good surface finishing.
4.High mechanical strength,low electrical resistance.
5.Resistant to cracking & spalling.
6.High resistance to oxidation and thermal shock.
Variety:
1. RP (Regular Power)
2. HP (High Power)
3. UHP (Ultra High Power)
4. RPI (Regular Power Impregnated)
(Notice: All of Graphite Electrodes is equipped to tapered nipple
