Abstract: METHOD FOR PRODUCING LEAD-BEARING STEEL AND THE PRODUCT PRODUCED THEREBY COMPRISING DISCHARGING A STREAM OF MOLTEN STEEL FROM A MELTING FURNACE TO A LADLE, AND ADDING LEAD TO THE STREAM OF MOLTEN STEEL AS IT IS BEING DISCHARGED FROM THE MELTING FURNACE AT TEMPERATUREA ABOVE 1600*C. AND CONTROLLING THE TEMPERATURE OF THE BATH, AND DISSOLVING OXYGEN IN THE BATH IN THE LADLE IN ORDER TO FAVOR THE FORMATION OF LEAD-OXIDE.

Abstract: An apparatus for making lead-bearing steel which comprises a melting furnace, and a ladle for receiving a stream of molten steel discharging from said melting furnace and spaced therefrom. The lead is fed to the stream of molten steel at a point where the latter is being poured from the melting furnace to the ladle. The latter has an interior bottom surface and a ladle outlet adjacent thereto. The ladle outlet prevents substantially any lead deposited on the interior bottom surface of the ladle from being discharged from the ladle, when the latter is poured or tapped.
