Higher Purity Graphite Electrode
At present, with the rapid development of large-capacity and ultra-high-power electric arc furnaces, the quality requirements for large-size and high-purity graphite electrodes are getting higher and higher. In the smelting process of DC electric arc furnace and AC electric arc furnace, the requirements of the power supply system (extreme voltage, current) in the initial melting, melting, oxidation and reduction stages are different, and their physical and chemical properties are also significantly different.
