Abstract
A process for the direct manufacture of steel, in which fine mineral is indirectly reduced and the iron sponge is melted, characterized in that the fine mineral in suspension in the exhaust gas of a preliminary reduction cyclone is introduced tangentially into a cyclone of preheating and, after being separated from the gas, at the base of the preheating cyclone, is suspended in the exhaust gas of a final reduction cyclone and fed tangentially to the preliminary reduction cyclone, the material outlet also being suspended solid of the latter in an exhaust gas, consisting of carbon monoxide, of a melting and refining group and tangentially feeding to the final reduction cyclone and because the discharge of solids from the final reduction cyclone is melted in the melting group and refining with simultaneous generation of the reduction gas by incomplete combustión of excess carbon and, subsequently, n, refining is carried out using oxygen.
