Abstract
1,243,443. Producing iron. O. JOHNSSON. July 21, 1969, No. 36663/69. Heading C7D. In the production of liquid pig iron or steel by smelting reduction, wherein a bath J of pig iron or steel is covered by an iron oxide-containing slag layer S to which iron oxide material, iron sulphide material, scrap, and/or other iron carrier is supplied, a free oxygen-containing gas is supplied directly into the slag layer (pipe L) to such a depth that CO, and, if reduction means containing H 2 or hydrocarbons are added H 2 , moving up through the slag layer will convert to CO 2 and H 2 O respectively to an extent of more than 70%, and reduction means is supplied directly to the iron bath J, e.g. if the C content of J is insufficient for smelting reduction, by pipe R, the relative concentrations of the ions in the slag layer being such that the ratio (Ca
