Regular power graphite electrodes allow the use of graphite electrodes with a current density of less than 17A/cm2, which are mainly used in ordinary power electric furnaces for steelmaking, silicon making, and yellow phosphorus making.

Instructions for use
1. Wet graphite electrodes should be dried before use.
2. Remove the foam plastic protective cap on the spare graphite electrode hole, and check whether the internal thread of the electrode hole is complete.
3. Clean the surface of the spare graphite electrode and the internal thread of the hole with compressed air that does not contain oil and water; avoid cleaning with steel wire or metal brush.
4. Carefully screw the connector into the electrode hole at one end of the spare graphite electrode (it is not recommended to directly install the connector into the electrode removed from the furnace), and do not hit the thread.
5. Screw the electrode sling (graphite sling is recommended) into the electrode hole at the other end of the spare electrode.
6. When lifting the electrode, put a soft object under one end of the spare electrode mounting connector to prevent the ground from damaging the connector; use a hook to extend into the hoisting ring of the spreader and then lift it. Lift the electrode smoothly to prevent the electrode from loosening from the B end. Take off or collide with other fixtures.
7. Lift the spare electrode above the electrode to be connected, align it with the electrode hole, and then slowly drop it; rotate the spare electrode to make the spiral hook and the electrode rotate and drop together; when the two electrode ends are 10-20mm apart, use compressed air again Clean the two end faces of the electrode and the exposed part of the connector; when the electrode is completely 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 a 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).
