Description of Graphite Electrodes and Nipple:

The main function of graphite electrodes is to conduct electrode conduction when smelting metals in electric arc furnaces. Due to the increasing proportion of steel smelted in electric arc furnaces globally, the use of electric arc furnaces to smelt steel plates and other secondary forming steels is the main item that consumes graphite electrodes. In addition, graphite electrodes are also used in smelting furnaces for melting non-ferrous metals, ceramics, and the waste recycling industry.

Graphite electrode joints are accessories for graphite electrodes. Graphite electrodes generally have higher requirements for joints. Joints generally have special production processes, which can be divided into (ordinary power graphite electrode joints, high-power graphite electrode joints, and ultra-high power graphite electrode joints) .

Features of Graphite Electrodes and Nipple:

1.Low electric resistance,
2.High density,
3.High anti-oxidation capability,
4.Precise machining accuracy.

Advantages of Graphite Electrodes and Nipple:

Graphite electrodes and nipple have the advantages of high strength, not easy to break, and good current passing.

Applications of Graphite Electrode and Nipple:

1. For EAF arc furnace;
2. For ore-thermal furnace; for the resistance furnace;
3. For the production of profiled graphite products;
4. For the production of shaped graphite products.

Diameter of electrodes: from 75 to 800mm. We can produce various specifications in accordance with customer requirements.
