The graphite electrode is mainly made of petroleum coke and needle coke, and coal tar is used as a binder. It is made by calcination, compounding, kneading, pressing, roasting, graphitization and machining. It is an electric arc in the electric arc furnace. A conductor that heats and melts the charge. Graphite electrodes are used in steelmaking electric arc furnaces and refining furnaces as conductive electrodes. It is used as a conductive electrode for industrial silicon furnaces, yellow phosphorus furnaces, corundum furnaces, and the like. The performance characteristics of the graphite electrode are good in electrical conductivity, strong in thermal shock resistance and high in mechanical strength.
When using a graphite electrode, the isoelectric diameter and diameter of the electrode should be appropriately selected according to the electric furnace capacity and the transformer load. When the electric furnace is charged, the bulk charge should be installed at the bottom of the furnace to prevent the furnace material from collapsing and breaking the electrode. During the exercise, lime and other non-conducting should be avoided. Many objects gather directly under the electrode, otherwise it will affect the energization of the electrode, and even cause the electrode to break and other precautions.
In order to effectively extend the service life of the graphite electrode, the side and bottom of the direct-injection graphite product are strongly corroded. During the application process, the graphite products are turned once a week, and an appropriate amount of combustion improver is used. The additive will reduce the life of the graphite products. Handle gently during handling, and it is strictly forbidden to shake. I hope this information can help you understand.
