Regular Power Graphite Electrodes are made of high quality petroleum coke and coal tar pitch produced by Petro China Fushun Petrochemical Company. They are refined by calcining, proportioning, mixing, pressing, roasting, graphitizing and machining. The nipples are made by one- immersion and two-firing process.Standard for HP Graphite Electrodes and NipplesItems | Unit | Nominal diameter (mm) |
