Performance of Graphite Electrodes
1.Low Resistivity 2.Good Electrical Conductivity 3.Good Anti-oxidation 4.High Mechanical Strength 5.Easily To Be Produced
Description of Graphite Electrodes
The graphite electrode is mainly made of petroleum coke and needle coke, and the coal bitumen is used as a binder. It is made by calcination, compounding, kneading, pressing, roasting, graphitization and machining. According to its quality, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.
Graphite Electrodes Varieties
For Direct Current Furnaces (Size: 22-32 inches):
Electrodes for Dc furnaces, which require 1 column of graphite electrodes. High maximum current density. The maximum diameter of these electrodes is 32 inches (801 mm).
For Alternating Current Furnaces (Size: 16-28 inches):
Alternating current furnaces require 3 columns of graphite electrodes. They mostly use 20-28 inch electrodes, the standard size in electric furnaces.
For Refining Furnaces (Size: 10-18 inches):
These electrodes are for refining materials like molten steel. Refining Furnaces have a smaller capacity than DC Furnaces.
Transportation of Graphite Electrodes
During the transportation of exporting, graphite electrodes are usually packaged in wooden cages, the nipples are packaged in wooden boxes. Sometimes, according to the requirements of the users, the electrodes and nipples will be packaged after connecting. The lining is made of waterproof and dust-proof plastic cloth, and the outer is fastened by steel belts, which is beautiful and firm.
