Abstract

<PICT:1019435/C6-C7/1> Molten iron is passed continuously through a vessel in which it is blown with air under such conditions that mainly only silicon is oxidized without the addition of any substantial amount of nitrogen to the bath. The metal is then transferred to a second non-rotary vessel containing a refining slag, and oxygen is blown in below the slag, there being relative motion between the bath and the location at which oxygen is introduced in addition to that resulting from the oxygen injection. This relative motion may be achieved by operating this stage as a continuous process, or, when operating as a batch process, by reciprocating the lance. Air is introduced above the bath, at least in the second stage, to burn the carbon monoxide evolved. A suitable form of apparatus is shown in Fig. 1, wherein molten iron charged continuously at T is blown with air by reciprocating lance 8 and is eventually discharged at 11 by means of launders 30, 31, 32 to one or more second stage vessels where it is blown with oxygen by lance 8c, finally leaving at 11a.
