Project introduction: Graphite electrodes are a large consumable material in the field of metallurgy and chemical industry, especially in energy-consuming industries such as steel metallurgy, aluminum electrolysis, magnesium electrolysis, polysilicon, and rare earth metallurgy. The resistivity of electrode graphite is one of the key factors affecting product energy consumption. Taking magnesium electrolysis as an example, calculated based on the current largest 430kA metal magnesium electrolysis cell, every 1Ωμ.m reduction in the anode graphite resistivity will reduce the DC energy consumption per ton of magnesium by 375kWh. The energy-saving effect is very obvious.

Main features: This technology mainly optimizes the formula and preparation process of the new graphite, greatly reduces the resistivity of graphite, and at the same time improves the strength of graphite electrodes. After surface treatment, the oxidation resistance of graphite electrodes is increased by 188 times, greatly extending the graphite electrodes. Service life under high temperature corrosion conditions.

Technical level: The technology is at the domestic advanced level.

Application prospect: Mainly used in the metallurgical industry.
