Low Power Graphite Electrode

The low power graphite electrodes produced by our company are mainly made from high-quality graphite, petroleum coke, needle coke as raw materials, and coal tar pitch as a binder. They are made through calcination, batching, mixing, molding, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of an arc in an electric arc furnace to heat and melt the furnace material; The graphite used has good crystallinity, high purity, low ash content, and fine particle size. Silicides, carbon fibers, and antioxidants are added in appropriate amounts to improve the mechanical strength, thermal shock resistance, oxidation resistance, and excellent conductivity and stability of low power graphite electrodes. Our manufacturing process has also optimized the electrode cross-sectional shape. Through our company's scientific research, we have found that low-power graphite electrodes can adopt more economical circular or rectangular cross-sections, or the optimal cross-sectional shape can be determined through simulation analysis to reduce resistance and energy loss. The internal structure adopts a multi-layer or composite structure design, with high-density graphite used internally to ensure conductivity, and low-density graphite used externally to increase thermal stability and thermal shock resistance. Adopting the method of reducing the number of interfaces between electrode segments, high-precision machining and high-quality welding technology are carried out by professional technicians to reduce the interface resistance and failure rate of low-power graphite electrodes.

The surface treatment process of low-power graphite electrodes adopts an anti-oxidation coating to extend the service life of graphite electrodes at high temperatures. A highly conductive coating is applied on the contact surface between the electrode and the furnace to reduce contact resistance and improve energy transmission efficiency. Through the optimization of the above design and production process, the low power graphite electrodes we manufacture have excellent quality, which can improve production efficiency, reduce energy consumption and costs.
