This patent describes a method of modifying an electric arc furnace to include oxy-fuel burners which assist in the melting of scrap metal. The furnace includes a bottom wall extending to a generally cylindrical side wall, and centrally located electrode means, comprising the steps of: (a) providing gas burners operable to emit hot combustion gases for melting scrap metal; (b) securing mounting means to the furnace to adjustably mount each of the burners to the furnace to flow combustion gases into the furnace along a firing direction extending downwardly at an angle of about 45 degrees and across an associated furnace cold spot; (c) selecting a burner firing rate for each of the burners within the firing rate range and operating each of the burners for a firing time of sufficient duration to provide a total heat energy output of from about 250,000 to about 350,000 BTU per ton of furnace capacity; (d) operating the furnace to determine the occurrence of any side wall wear locations and unmelted scrap metal locations and the burner primarily affecting such locations; (e) adjusting the mounting means to laterally vary the firing direction of the burner primarily affecting the location of side wall wear radially inwardly and to laterally vary the firing direction of the burner primarily affecting the location of any unmelted scrap metal toward such scrap metal; (f) operating the furnace to determine the continued occurence of the side wall wear and unmelted scrap locations determined in step (d).
