| description | PURPOSE: A working method of an electric furnace is provided to prevent the waste of resources by recycling slag. CONSTITUTION: A working method of an electric furnace comprises the steps of: preparing slag, charging the slag with scrap into an electric furnace, melting the scrap and slag, consecutively excluding slag produced during reaction of the molten scrap and slag, charging a supplementary material including quicklime, and making the molten steel react with the supplementary material in the electric furnace. [Reference numerals] (AA) Collecting electric furnace slag; (BB) Making the electric furnace slag into aggregate; (CC) Charging scrap and the electric furnace slag into an electric furnace; (DD) Generating arc in the electric furnace to melt the scrap and electric furnace slag; (EE) Charging a subsidiary material(quicklime) in the electric furnace; (FF) Consecutively excluding electric furnace slag; (GG) Making molten steel react with the subsidiary material in the electric furnace; (HH) Tapping the molten steel |
