Graphite electrodes should be used strictly according to instructions
Graphite electrodes are not unfamiliar to each of us. The main component is graphite, which has become the best conductive material today. Graphite electrodes also need to strictly follow the instructions during use.
Firstly, open the protective cap on the hole to check the integrity of the electrode thread.
Under the premise of determining the integrity, the next step is to clean the internal thread of the hole and the surface of the spare graphite electrode.
Insert the connector into the electrode hole, and the electrode hanger is connected to the other end.
Remove the electrode. Take care not to let the electrode collide with other fixtures.
Hang the spare electrode above the electrode to be connected. When the two electrode end faces are 10-20mm apart, clean the exposed ends of the two electrode ends and the joints again with compressed air, and be lighter to avoid damage to the electrode holes and the threads of the joints.
Tighten the spare electrode.
We need to remind everyone here that if the graphite electrode is found to be wet, it should be dried. More use considerations from china-graphiteelectrode.com
1. Dry graphite electrodes before use.
2. Remove the protective foam cap from the spare graphite electrode hole, and check whether the internal thread of the electrode hole is complete.
3. Use compressed air that does not contain oil and water to clean the surface of the spare graphite electrode and the internal thread of the hole; avoid cleaning with steel wire clumps or metal brushes.
4. Carefully screw the connector into the electrode hole of one end of the spare graphite electrode (it is not recommended to directly insert the connector into the electrode removed from the furnace). Do not hit the threads.
5. Screw the electrode spreader (graphite spreader is recommended) into the electrode hole on the other end of the spare electrode.
6. When lifting the electrode, place a loose object under the end of the spare electrode mounting joint to prevent the ground from damaging the joint; use a hook to reach into the lifting ring of the spreader and lift it, and lift the electrode smoothly to prevent the electrode from loosening from the B end Disengage or collide with other fixtures.
7. Hang the spare electrode above the electrode to be connected, and slowly drop it after aligning the electrode hole; rotate the spare electrode so that the spiral hook and the electrode rotate together and fall; when the end faces of the two electrodes are separated by 10-20mm, use compressed air again Clean the two end surfaces of the electrode and the exposed part of the connector; when the electrode is fully lowered at the end, it should not be too strong, otherwise the electrode hole and the thread of the connector will be damaged due to violent collision.
8. Use a torque wrench to screw the spare electrode until the end faces of the two electrodes are in close contact (the correct connection gap between the electrode and the connector is less than 0.05mm).
