We need to know that the first wet graphite electrode should be dried before use, and check whether the thread inside the electrode hole is complete. When we use compressed air to clean the spare graphite electrode surface and hole internal thread, there shall be no oil or water; Avoid cleaning with wire or metal brush cloth.

　　It is important to carefully screw the connector into the electrode hole of the spare graphite electrode and screw the electrode sling (graphite sling is recommended) into the electrode hole at the other end of the spare electrode. When lifting the electrode, the cushion cushion is soft to the bottom of the spare electrode assembly connector end to prevent ground damage and joint damage; The lifting hook extends to the lifting ring of the lifting device to lift the lifting electrode smoothly to prevent the electrode from being released from end B or colliding with other fixing devices.

Secondly, the standby electrode is hoisted to the top of the electrode to be connected, aligned with the electrode hole, and then slowly down; Rotate the spare electrode to make the screw hook rotate down with the electrode. When the graphite electrode is finally put down completely, do not use too much force, otherwise the pole hole will damage the joint thread and other details due to violent collision.

We want to ensure as far as possible the early processing to ensure the stable quality of graphite brought by the later period.
