Water-cooling fixed trough for electric furnace

The utility model relates to the technical field of electric furnaces, discloses a water-cooling fixed trough for an electric furnace, and solves the technical problems that cooling water can be guided through an internal circulating water trough formed among steel plates, an outer side plate and an inner side plate, and the water-cooling efficiency can be reduced once gaps exist among the steel plates or the sealing performance is reduced. Comprising a water tank and an electric furnace charging trough, a liquid level window is fixedly arranged on the surface of the water tank, a water pump and a cooling-water machine are fixedly installed at the top end of the water tank, the water outlet end of the water pump is fixedly connected with the water inlet end of the cooling-water machine through a guide pipe, and the two sides of the top end of the water tank are fixedly connected with the two sides of the bottom end of the electric furnace charging trough through trapezoidal supporting plates; the snakelike co
