Product Introduction of Graphite Cathode Block:
Graphite Cathode Block, with high-quality petroleum coke as the main raw material, and pitch as the binder. After molding, roasting (dipping, re-roasting), graphitization, and finishing, it is finally made. Mainly used in large-scale aluminum electrolytic cells, this product has obvious power saving effect and makes the cell long life.
