When connecting, use compressed air to blow the electrode socket, electrode end face and the nipple clean, no dust and abnormal objects embedded. The connection should be kept clean and flat. When the two electrodes are screwed in to a certain extent (the gap is about 10mm), then blow again with compressed air, and then tighten the electrode with torque pliers. The torque applied during tightening should be appropriate. If there is a gap in the connection after tightening, it must be withdrawn and reconnected until there is no gap.
Precautions for the use of graphite electrodes:
① For wet graphite electrodes, dry them before use.
② Remove the foam protective cap from the spare graphite electrode hole and check whether the inner thread of the electrode hole is complete.
③ Clean the surface of the spare graphite electrode and the inner thread of the hole with compressed air free of oil and water, and avoid cleaning with steel wire balls, metal brushes, and emery cloths.
④ Carefully screw the joint into the electrode hole at one end of the spare graphite electrode (it is not recommended to put the joint directly into the electrode removed from the furnace) without colliding with the thread.
⑤ Screw the electrode sling (a graphite sling is recommended) into the electrode hole at the other end of the spare electrode.
⑥ When lifting the electrode, place a soft object under the end of the spare electrode installation joint to prevent the ground from damaging the joint. Insert the hook into the lifting ring of the sling and lift it up. Lift the electrode smoothly to prevent it from falling off from the B end or colliding with other fixtures.
⑦ Hang the spare electrode above the electrode to be connected, and then slowly drop it after aligning with the electrode hole; rotate the spare electrode so that the spiral hook and the electrode can rotate and fall together; when the end faces of the two electrodes are 10–20 mm apart, clean the electrode with compressed air. When the electrode is fully lowered at the end, do not use too much force; otherwise, the thread of the electrode hole and the connector will be damaged due to a violent collision.
⑧ Use a torque wrench to twist 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).
