Abstract (en)
A method for cooling a vertical train of graphite electrodes (10; 36) connected to each other, by using a cooling liquid (11) sprayed onto the outer periphery surface of at least one graphite electrode (10; 36) consisting of an upper portion of said graphite electrode train, said graphite electrode train either penetrating through a cover (1) enclosing an opening of an electric arc furnace with a vessel for melting and refining a metal, such as steel or the like, and extending into said vessel, or penetrating through a cover enclosing an opening of a ladle (30) for receiving, melting and refining secondarily a metal molten and refined in a furnace, and extending into said ladle. The method is characterized by the steps of directing said cooling liquid at the upward or downward inclination (θ) of 0 degrees to 60 degrees with respect to the horizontal level (L-L) and spraying said cooling liquid (11) simultaneously at a flow rate ranging between 0.8 liters/minute and 40 liters/minute. <IMAGE>
