Advantages of Graphite electrode:
1. Reduce graphite electrodes lateral oxidation rate.
2. Lessen graphite electrodes consumption rate by 15%~20%.
3. Improve graphite electrodes cost efficiency.
4. It is a more cost-effective solution through reducing graphite electrodes purchasing cost by 10%~15%.
5. It is a production efficiency improving solution through reducing risk of graphite electrodes breakage and falling down.
