Patent Images
1. A graphite arc furnace electrode comprising:
- an elongated graphite body having substantial length and diameter;
connecting end surfaces formed on said graphite body for connecting said graphite body to another graphite body;
a T-shaped mound formed on one connecting end surface extending across the middle portion thereof;
an inverted T-shaped groove formed on the other connecting end surface extending across the middle portion thereof;
said mound and groove being gradually decreased in width longitudinally toward one end thereof, the width of said mound being in a range of 1/3 to 2/3 based on the length of lateral direction of said connecting end surface at the central point of height and length of said mound, said mound having a lateral inclination of 45 to 87 degrees with respect to said connecting end surface, the maximum width of an upper surface of said mound being 3/4 or less based on the length of lateral direction of said connecting end surface and the minimum width of a base of said mound being 1/4 or more based thereon.
