摘要
An existing steel making installation having a basic oxygen furnace facility is converted to an electric arc furnace facility for refining steel by modifying the furnace support pedestals to form spaced apart horizontal rail support pads and spaced apart rails are mounted on the pads and a superstructure extending horizontally at one side of the space formally occupied by the basic oxygen furnace. An electric arc furnace is mounted on a furnace transfer car for movement along newly installed horizontal rails between a furnace operating position and a furnace exchange position. The electric furnace having a tapping orifice for discharging treated steel and a slag discharge trough. Ladle transfer cars previously used for handling slag and steel from the basic oxygen furnace are reused for the same purpose during operation of the electric arc furnace. A fume opening in the electric furnace roof is connected by a vertical fume section and an elbow to the existing fume system. Bins used for supplying materials to the basic oxygen furnace are used to supply in some instances different materials to the electric arc furnace.
