Graphite electrode cooling method used for melting and refining metal in electric arc furnace and ladle

摘要

The present invention relates to a method for cooling a vertical train of a graphite electrode used for arc heating a metal such as steel in an electric arc furnace or a ladle containing a metal emitted from an electric arc furnace. The graphite electrode is cooled by spraying on the outer surface of the graphite electrode train inclined upwardly or downwardly with respect to the graphite electrode train, the graphite electrode train having a nipple penetrating through a cover for sealing an opening of an electric arc optical path for melting and refining metal. A plurality of graphite electrodes connected vertically to each other through the.
