摘要： 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.
摘要翻译：一种通过使用喷射到至少一个石墨电极（10; 36）的外周表面上的冷却液（11）来冷却相互连接的垂直石墨电极（10; 36）的方法，所述石墨电极所述石墨电极组或者穿过用围绕电弧炉的开口的盖（1）以及用于熔化和精炼金属（例如钢等）并且延伸到所述容器中的容器，或者穿透包围钢包（30）的开口的罩，用于接收，熔化和精炼在熔炉中熔化和精炼的金属，并延伸到所述钢包中。该方法的特征在于，将所述冷却液体以相对于水平面（LL）为0度至60度的向上或向下倾斜（θ）引导并且以流速范围同时喷射所述冷却液体（11）在0.8升/分钟和40升/分钟之间。
