The proposed method is characterized in that the liquid bath is constituted by the melt of a low-carbon steel and molten slag. Oxidation and reducing zones are created through which, along a closed path an the surface of the molten low-carbon steel, is circulated the molten slag, into which are blown powder slag materials which are melted with the heat of a fuel-oxygen torch immersed into the melt, The said method is carried out in a melting reservoir shaped as a closed annular chamber (1) provided with partitions (11) hermetically dividing the gas space above the molten slag into oxidation (6) and reducing (7) zones.
