description The utility model relates to a cooling device for a central small furnace cover of an electric arc furnace, which is characterized in that the cooling device is provided with an annular pipeline (1); a water inlet pipe (2) is arranged on the annular pipeline (1); the other side of the annular pipeline is broken and provided with an opening (3) corresponding to the water inlet pipe (2); pipeline ports (4) at two sides of the opening (3) are sealed; and a plurality of water outlets (5) which tilt a certain angle outwards are uniformly distributed below the annular pipeline (1). The cooling device is arranged above the central small furnace cover of the electric arc furnace and has simple structure and convenient use. In addition, the temperature of the central small furnace cover, particularly the triangular area of an electrode hole is lowered, and the life of the small furnace cover is prolonged without damaging the refractory material of the central small furnace cover by mainly using the direct cooling and
