PCT No. PCT/SU91/00183 Sec. 371 Date May 12, 1993 Sec. 102(e) Date May 12, 1993 PCT Filed Sep. 17, 1991 PCT Pub. No. WO92/05288 PCT Pub. Date Apr. 2, 1992.The proposed method is characterized in that the liquid bath is constituted by the melt of low carbon steel and molten slag. Oxidation and reducing zones are created through which, along a closed path on 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 melting 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.
