发明名称 Método para produção de metal líquido e usina para execução do método
摘要 <p>With a method for producing liquid metal from charging substances containing ore and of fluxes, the ore is directly reduced to sponge metal in at least one reduction zone (5, 7, 8), the sponge metal is melted along with fluxes in a melt-down gasifying zone (11) under the supply of carbon carriers and an oxygen-containing gas. A CO- and H2-containing process gas serving as a reducing gas is produced, fed into the reduction zone (5, 7, 8), reacted there, and subsequently withdrawn, wherein slagforming fluxes, in particular calcium carbonate, dolomite etc., gas are calcined by the process gas in a calcining zone (26') that is separate from the reduction zone (5, 7, 8) and melt-down zone (11). To be able to employ slagforming fluxes of any desired grain and without disturbances of the reduction process, the calcining zone (26') is connected in parallel to the reduction zone (5, 7, 8) with respect to the material flow and the calcined fluxes are fed into the melter gasifier (10) directly.</p>
