Title:
GRAPHITE ELECTRODE FOR STEELMAKING
Document Type and Number:
WIPO Patent Application WO/2004/063651
Kind Code:
A1
Abstract:
A graphite electrode that can be effectively prevented from oxidizing and consuming during operation of an electric steel furnace, so that specific consumption of the electrode can be improved. The graphite electrode is used in an electric steel furnace that is operated while the electrode projecting upward from a furnace cover is cooled by cooling liquid that is sprayed on the surface of the electrode. The graphite electrode is characterized in that a concave and convex structure is formed on its surface.
