1. The graphite electrodes that are damp and wet should be dried before use.

2. Remove the foam 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 without oil and water; avoid cleaning with steel wire groups or metal brush emery cloth.

4. Carefully screw the joint into the electrode hole of one end of the spare graphite electrode (it is not recommended to load the joint directly into the electrode removed from the furnace), and do not collide with the thread.

5. Screw the electrode spreader (a spreader made of graphite is recommended) into the electrode hole at the other end of the spare electrode.

6. When lifting the electrode, pad the soft object to the bottom of one end of the spare electrode fitting joint to prevent the ground from damaging the joint; use the hook to extend into the lifting ring of the spreader and lift it up. The lifting electrode should be stable to prevent the electrode from loosening from the B end. Or collide with other fixtures.

7. Hang the spare electrode above the electrode to be connected, align it with the electrode hole and slowly fall; rotate the spare electrode to make the spiral hook rotate and descend together with the electrode; when the two electrode extreme surfaces are 10-20mm apart, use compressed air again Clean the exposed parts of the two end faces of the electrode and the joint; when the electrode is completely lowered at the end, it should not be too violent, otherwise the threads of the electrode hole and the joint 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 joint is less than 0.05mm).

Graphite is very ubiquitous in nature, and graphene is the strongest substance known to man, but scientists may still need to spend years or even decades to find a way to convert graphite into large sheets of high-quality graphene "thin films", so that they can be used to make various useful substances for mankind. According to scientists, in addition to being exceptionally strong, graphene also has a series of unique properties. Graphene is also the most conductive material known so far, which makes it The field of microelectronics also has great application potential. Researchers even see graphene as a replacement for silicon that can be used to produce future supercomputers.
