ABSTRACT:
A metallurgical plant is provided with a plurality of electric arc furnace vessels arranged so that the centers of the vessels lie along the points of an imaginary circle. A lid having the electrical supply for the furnaces is rotatable onto the furnaces by having its pivot point positioned at the center of the imaginary circle.
Other features of the plant are disclosed including the use of open-topped support members for supporting the vessels; gate type valves at the bottoms of the vessels for tapping; below-the-charging-floor rail tracks for transporting the products of the vessel; a mechanism for lifting, on one side, the vessels to selectively skim off the slag layer; etc.
