High-power graphite electrodes

High-power graphite electrodes refer to graphite electrodes that allow the use of current density greater than 17A/cm, and are mainly used in high-power electric arc furnaces for steelmaking.

The difference between high-power graphite electrodes and ordinary power graphite electrodes is that the current densities allowed are different. The current density allowed for high-power graphite electrodes is much larger than that of ordinary power graphite electrodes, so the metal can be heated and melted faster in electric arc furnaces.

The electrode diameters are different. The diameter of high-power graphite electrodes is usually larger than that of ordinary power graphite electrodes. This is to adapt to higher current densities.

The electrode lengths are different. The length of high-power graphite electrodes is usually shorter than that of ordinary power graphite electrodes. This is to reduce electrode resistance and heat loss.

The manufacturing processes are different. The manufacturing process of high-power graphite electrodes is more complicated than that of ordinary power graphite electrodes, requiring a higher technical level and stricter quality control. High-power graphite electrodes have good conductivity, thermal stability, and corrosion resistance, making it an indispensable and important material in the steelmaking industry.
