Title:
GRAPHITE ELECTRODE FOR STEEL MAKING
Document Type and Number:
Japanese Patent JP2004220826
Kind Code:
A
Abstract:
To provide a graphite electrode for steel making capable of effectively preventing oxidation consumption in operating the graphite electrode used for an electric steel making furnace, and of improving an electrode specific consumption.
This graphite electrode of the electric steel making furnace is operated while being cooled by spraying a cooling liquid to the surface of the graphite electrode projecting upward from a furnace cover. The graphite electrode is characterized by forming an uneven structure on the surface of the graphite electrode.
