High power graphite electrode

Graphite electrodes are used primarily in electric arc furnace steel manufacturing. Graphite electrodes can provide high levels of electrical conductivity and capability of sustaining the extremely high levels of generated heat. Graphite electrodes are also used in the refinement of steel and similar smelting processes.

1. The electrode holder should be held in the place beyond the security line of the top electrode; otherwise the electrode would be easily broken. The contact surface between the holder and the electrode should be cleaned up regularly to maintain a good contacting. The cooling jacket of the holder shall be avoided from water leakage.

2. Identify the reasons if there is gap in the electrode junction, do not use the muntil the gap is eliminated.
3. If there is falling off of nipple bolt when connecting electrodes, it is necessary to complete the nipple bolt.
4. The application of electrode should avoid of tilting operation, particularly, the group of connected electrodes should not be put horizontally so as to prevent from breaking.
5. When charging materials to the furnace, the bulk materials should be charged to the place of the furnace bottom, so as to minimize the impact of the large furnace materials on the electrodes.
6. The large pieces of insulation materials should be avoided of stacking on the bottom of the electrodes when smelting, so as to prevent from affecting the electrode use, or even broken.
7. Avoid of collapsing the furnace lid when rising or dropping the electrodes, which may result in electrode damage.
8. It is necessary to prevent the steel slag from splashing to the threads of the electrodes or nipple stored in the smelting site, which my damage the precision of the threads.
