Abstract

158,523. Basset, L. P. Oct. 3, 1917, [Convention date]. Extracting.-Iron ore is reduced by means of the exact quantity of carbon necessary, or by means of carbon monoxide, and the resulting spongy iron is melted in a. flame consisting of carbon monoxide produced by the combustion of finely-divided carbon or other material such as crude petroleum, the proportion of petroleum to air being so determined that at the temperature employed the hydrogen remains free while the carbon burns to carbon monoxide. The richness of the flame in carbon or oxygen may be slightly varied in order to carburize or refine the metal. The ore mixed with carbon may be reduced in externally heated vertical or other retorts b, Fig. 1, from which the spongy iron is discharged to a reverberatory furnace c fed with flour carbon and air through a tuyere e, part of the carbon monoxide which is produced being utilized for heating the retorts b and part for heating the air supply for the tuyere e. After the metal has been melted in the furnace c, the slag is run off and the metal is finished with additions of carbon, manganese, &c., or by means of an oxidizing-flame- The retorts b may discharge into a passage leading to a separate reverberatory furnace or into a vessel in which the metal is cooled before being admitted to the furnace. The reduction of the ore and the melting of the metal may be effected ia succession in a single reverberatory furnace c<1>, Fig. 2, connected with air-heating regenerators n, o, and heated by tuyeres e, e<1>, the direction of the air and gases being reversed periodically; or two furnaces arranged side by side and worked in series in opposite directions alternately may be used ; or four furnaces may be arranged in a cyclic series. In further modifications, the spongy iron may be produced in a rotary furnace and charged into a melting-furnace. The Specification, as open to inspection under Sect. 91 (3) (a) states also that the method may be applied to the treatment of scrap with or without the addition of new spongy iron. This subjectmatter does not appear in the Specification as accepted.
