Products Processing:
Graphite Electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch.
After Raw Material calcining, crushing, screening, burden, kneading, forming, baking, impregnation, graphitization and then precision machined with professional CNC machining.
such of the products own characteristics with low resistivity, good electrical conductivity ,low ash, compact structure, good anti oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace and smelting furnace.
Applications:
1. For Ladle furnaces
2. For Electric arc furnace steel making
3. For Yellow phosphorus furnace
4. Apply to Industrial silicon furnace or melting copper.
5. Apply to Refine steel in ladle furnaces and in other smelting processes

Products Transportation and Installation Introductions:
(1)The Electrodes should be kept in a clean, drying place and avoid vibrations and collisions. It should be dried before use.
(2) When installing the joint, please clean the hole with the compressed air, then carefully screw the joint and not damage the thread.
(3)When connecting electrodes, the two electrodes should be cleaned with compressed air when they are 20-30mm apart.
(4)When using a wrench to connect the electrode, it should be completely taut to the specified position so that the gap between the two electrodes is not less than 0.05mm
(5)To avoid the electrode fracture, please avoid the insulation block.
(6)To avoid the electrode fracture, please place the bulk block in the upper part.
