<p>PCT No. PCT/SU87/00023 Sec. 371 Date Oct. 5, 1988 Sec. 102(e) Date Oct. 5, 1988 PCT Filed Feb. 16, 1987 PCT Pub. No. WO88/06190 PCT Pub. Date Aug. 25, 1988.The hereinproposed method and furnace provide for preliminary building up of melt in a melting pot (10) of a rectangular shape in the horizontal section, delivery of an oxygen-containing gas (3) into the melt below its surface level through tuyeres (13) with nozzles (14) installed in the longer walls of the melting pot (10) creating two melt zones: an upper zone (9) loaded with solid carbon fuel (2) in an amount sufficient for providing a volumetric concentration of said fuel within 0.5 to 50% of the melt volume in said zone (9), wherein said concentration is maintained by subsequent concurrent loading of iron-bearing material (1) and solid carbon fuel (2), and a lower zone (8) consisting of a layer of slag (4) and a layer of ferrocarbon intermediate product (5) said layers being discharged separately through channels (17 and 18) made in the counterproposed short walls of the melting pot (10). The ratio of the horizontal section area of the melting pot (10) at the installation level therein of tuyeres (13) to the total area of the outlet holes of the nozzles (14) is 300-10000, while the distance (h) from the lower boundary of the product discharge channel (18) to the upper boundary of the slag discharge channel (17) is 0.3 to 0.75 the distance (H) from the lower boundary of the product discharge channel (18) to the installation level of the tuyeres (13).</p> |
