High-power graphite electrodes . This type of electrode is characterized by low resistivity, allowing the current higher than that of ordinary electrodes; allowing current density to be more than twice as large; low thermal expansion coefficient; flexural strength High; low oxidation loss.The production of high-power and ultra-high-power electrodes uses needle coke as the raw material, and the production process uses multiple immersion and roasting to increase the graphitization temperature.The specification model is 200mm-700mm in diameter.
