⚙️ Product Processing
Graphite electrodes are manufactured from high-quality, low-ash raw materials such as petroleum coke, needle coke, and coal tar pitch.
The production process includes: calcination of raw materials → crushing → screening → batching → kneading → forming → baking → impregnation → graphitization → precision CNC machining.
The finished products feature low electrical resistivity, excellent electrical conductivity, low ash content, compact structure, good oxidation resistance, and high mechanical strength, making them the ideal conductive material for electric arc furnaces and smelting furnaces.

🔧 Transportation & Installation Guide
-
1Electrodes should be stored in a clean, dry place, away from vibration and impact. They should be dried before use.
-
2When installing the joint, clean the socket hole with compressed air, then carefully screw in the nipple without damaging the thread.
-
3When connecting electrodes, both electrodes should be cleaned with compressed air when they are 20–30 mm apart from each other.
-
4When using a wrench to connect the electrode, it must be fully tightened in the specified position so that the gap between the two electrodes is no more than 0.05 mm.
-
5To avoid electrode breakage, avoid using an insulating block.
-
6To avoid electrode breakage, place the support block at the upper part of the electrode.
❓ Frequently Asked Questions (FAQ)
Q
What is an HP grade graphite electrode and where is it used?
