Graphite electrode is a kind of high temperature and oxidation-resistant conductive material which is made of petroleum coke and coal tar is used as the binder, produced by crushing, blending, kneading, shaping, roasting, impregnation, graphitization, machining and a series of processes. Graphite electrodes have good electrical properties and chemical stability, high mechanical strength at high temperatures, low impurity content, and good vibration resistance. It is a good conductor of heat and electricity. It is widely used in an electric arc furnace, refining furnace, ferroalloy production furnace, industrial silicon furnace, yellow phosphorus furnace, corundum furnace and other smelting furnaces that use an electric arc to produce high temperature.
According to different power and current, it is produced by different raw materials and production processes. It can be divided into regular power graphite electrode, high power graphite electrode, and ultra-high power graphite electrode. According to the diameter of the electrode, there are different specifications of φ75~600mm. According to the special requirements of users, it can process and produce graphite electrodes and special-shaped graphite products with special specifications.
Regular power graphite electrode: It is allowed to use a graphite electrode with a current density lower than 17A/cm2, which is mainly used for regular power electric furnaces such as steelmaking, silicon refining, and yellowing phosphorus.
High power graphite electrode: It is allowed to use a graphite electrode with a current density of 18~25A/cm2, mainly used in high power electric arc furnace for steel making.
Ultra High Power Graphite Electrode: It is allowed to use graphite electrodes with current densities greater than 25 A/cm2, which is mainly used in ultra-high power steelmaking electric arc furnaces.
Our company is mainly engaged in the manufacture, research, and sales of graphite electrodes and related carbon products. If you have any demand for our products, please feel free to contact us.
