A method for producing carburized iron by reduction in the liquid phase in a rotating furnace

摘要

Process for the production of liquid carburized iron by direct reduction in liquid phase, of iron-containing materials in an essentially cylindrical vertical reactor, rotating around its geometrical axis, wherein the material containing iron in oxidized state mixed with flux and the reducing material is fed while the reactor is in motion, in alternate layers, which owing to the centrifugal force or to their own friction, adhere to the internal wall of the reactor, the layer next to the reactor wall consisting of the reducing material and the adjacent layer, situated nearer the geometrical axis of the reactor consisting essentially of material containing iron in oxidized state mixed with a fluxing agent and wherein the carbon monoxide developed in the reduction reactions occurring between the hereinbefore said layers is entirely burnt to carbon dioxide by means of a jet of pure oxygen injected into the reactor.
