Abstract
An embodiment disclosed herein includes a monolithic graphite electrode. The electrode has a main body having a length of more than 3050 mm. Another embodiment disclosed herein includes an electrode column comprising a plurality of monolithic graphite electrodes. The column has a length of more than 3050 mm of electrode per joint. A further embodiment discussed herein is the practice of increasing the length of the electrode to minimize the occurrence of an electrode joint in the electrode column for a given length. This practice will improve efficiencies for both electrode manufacturers as well as electric arc furnace operators.
