  • Method of obtaining steel in a liquid bath and the device to carry it out
    Patent number: 5336296
    Abstract: 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.
