What can not be done in the use of graphite electrode?
1、The graphite electrode manufacturer indicates that the connector should be carefully screwed into the hole of the spare graphite electrode (it is not recommended to install the connector directly into the electrode taken out of the furnace).No thread will collide.
2、Remove the foam cover from the spare graphite electrode hole.Check integrity of thread in electrode hole.
3、Dry the wet graphite electrode before use.
4 Rotate the electrode coater (graphite coater recommended) into the electrode hole at the other end of the spare electrode.
5 when lifting the electrode, the joint should be prevented from damage;Cushion loose material at the end of the connector at the spare electrode.The lifting electrode should be stable.After entering the lifting ring with the hook, lift the lifting ring to prevent the electrode end B from loosening or colliding with other fixing devices.
6、Clean the surface and threaded holes of the spare graphite electrode with oil-free and water-free compressed air.Avoid using steel wire or metal brush to clean emery cloth.
7 Hang the standby electrode above the electrode to be connected, align the standby electrode with the electrode hole, and slowly lower the standby electrode.After the electrode is completely lowered, do not apply too much, otherwise it will be damaged by violent collision.Rotate the spare electrode so that the spiral hook rotates downward with the electrode;When the tops of the two electrodes are 10-20 mm apart.Then clean the end faces and exposed parts of the connector with compressed air, which may damage the electrode holes and the connector threads.
8 Tighten the spare electrode with a torque wrench until the top surfaces of the two electrodes are in close contact (the correct connector between electrode and connector is less than 0.05mm).
