Instructions For Graphite Electrode

Apr 24,2019January 10, 2019
1. Dry the wet graphite electrode before use.
2. Remove the foam cap on the spare graphite electrode hole and check whether the internal thread of the electrode hole is complete. 
3. Clean the surface of spare graphite electrode and internal thread of the hole with oil and water free compressed air; Avoid the use of wire or metal brush emery cloth cleaning.

4. Carefully screw the joint into the electrode hole of one end of the spare graphite electrode (it is not recommended to directly install the joint into the electrode hole of the furnace to remove the removed electrode), and do not impact the thread.
5. Screw the electrode spreader (graphite spreader is recommended) into the electrode hole on the other end of the standby electrode. 
6. When hoisting the electrode, cushion soft material should be placed under one end of the joint of the spare electrode to prevent the ground from damaging the joint; After the hook is extended into the lifting ring of the spreader, the lifting electrode should be stable to prevent the electrode from loosening at the B end or colliding with other fixing devices.
7. Hang the spare electrode above the electrode to be connected and slowly drop it after aligning the electrode hole; Rotate the spare electrode to make the screw hook and electrode rotate and descend together; When the distance between the two electrode ends is 10-20mm, the exposed parts of the two electrode ends and the joint are cleaned with compressed air again. When the electrode is finally completely lowered, it shall not be too hard, otherwise the electrode hole and the thread of the joint will be damaged due to violent collision.
8. Twist the spare electrode with a torque wrench until the end faces of the two electrodes are in close contact (the correct joint between the electrode and the joint is less than 0.05mm).
