ABSTRACT:
A cover with a spray cooling system for the main body of an electric furnace is of a double-layered structure with a hollow inner space in which are provided a plurality of spray nozzles such that cooling water sprayed therefrom will cool the cover. A water collecting box with one or more water outlets is attached to the outer circumferential side surface of the cover such that its bottom surface is below the bottom surface of the cover, and the interior of the box is connected to the hollow inner space of the cover such that the sprayed cooling water can be discharged without the use of a vacuum pump and does not cover the inner surface of the inner space to prevent uniform and efficient cooling of the cover.
