Graphite Electrode
Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch is used as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It is used in electric arc furnaces to release electric energy in the form of electric arcs. The conductors that heat and melt the charge can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes according to their quality indicators.
The main raw material for graphite electrode production is petroleum coke. A small amount of pitch coke can be added to ordinary power graphite electrodes, and the sulfur content of petroleum coke and pitch coke is not allowed to exceed 0.5%. Needle coke is also required to produce high-power or ultra-high-power graphite electrodes. Both petroleum coke and pitch coke meet the relevant national quality standards. Mainly used in metal smelting electric arc furnaces, submerged electric furnaces, resistance furnaces and used to prepare special-shaped graphite products, etc.
Our Product Advantages
1. The discharge speed is fast, the accuracy is high, the material is not easy to be deformed, and the thermal expansion coefficient is small.
2. Easy to polish, fast processing speed, no burrs after processing.
3. The loss is small, the carbon atoms in the spark oil are decomposed at high temperature, and a protective film is formed on the surface of the electrode, which compensates for the loss of the electrode.
4. Light weight, low density and low cost.
5. Low resistivity, good electrical and thermal conductivity.
6. Strong resistance to thermal shock and mechanical vibration, high mechanical strength, and good machining performance.
