    摘要： The present invention pertains to metallurgical processes and equipment and, more particularly, to a metallurgical furnace capable of operating with a broad range of broad range of raw materials and fuels, including those with high levels of impurities. Accordingly, the metallurgical furnace of the present invention comprises (i) at least an upper tub (1), (ii) at least a lower tub (2), (iii) at least a fuel feeder positioned substantially between the at least an upper tub (1) and the at least a lower tub (2), (iv) at least a row of tuyeres (3, 4) positioned on at least one of at least an upper tub (1) and at least a lower tub (2), the at least a row of tuyeres (3, 4) fluidly communicating inside the furnace with the outside environment, and (v) at least a burner (10) positioned on at least one of at least an upper tub (1) and at least a lower tub (2). The use of at least a burner (10) jointly with the at least a row of tuyeres (3, 4) generates a very intense release of heat by virtue of the exothermic reactions which occur by this combination.

    摘要： A multiple hearth furnace comprises a gas cooling system for its central shaft (20) and its rabble arms (26). This gas cooling system includes within the shaft (20) an annular main distribution channel (54, 54') for supplying a cooling gas to the rabble arms (26) and a central exhaust channel (56) for evacuating the cooling gas leaving said rabble arms (26). The gas cooling system further comprises an annular main supply channel (52, 52') surrounding the annular main distribution channel (54, 54') and being outwardly delimited by an outer shell (50) of the shaft. A cooling gas inlet (44', 44') is connected to the annular main supply channel (52, 52'). A cooling gas passage (60', 60'') between the annular main supply channel (52, 52') and the annular main distribution channel (54, 54') is spaced from the cooling gas inlet (44', 44'), so that cooling gas supplied to the cooling gas inlet (44', 44') has to flow through the annular main supply channel (52, 52') through several hearth chambers (12) before it flows through the cooling gas passage (60', 60') into the annular main distribution channel (54, 54').

    摘要： The present invention refers to a method and an equipment for curing and drying self-reducing agglomerates containing cement as a binder in the presence of saturated vapor at a temperature from about 70 to about 110°C and under atmospheric pressure. The treatment is performed in one single equipment. The self-reducing agglomerates are comprised of mixtures of fines of iron ore and/or industrial residue containing iron oxides and/or metallic iron, fines of carbonaceous materials such as mineral coal, charcoal, green petroleum coke and similar fines fluxing material such as steel plant slag and blast furnace slag, limestone, lime and similar materials, cement as a binder and fluxing agent, and humidity between 7 and 12%, produced in pellet-making units and/or briquette-making units and thereafter treated using one single piece of equipment, involving the steps of predrying with heated gasses (2), curing with saturated vapor (3) and drying with heated gasses (4) performed continuously and sequentially, controlling the discharge velocity (5) in order to allow the time of permanence of the agglomerate within the equipment to be from about 4 to about 12 hours. The cured and dried agglomerate may be processed in an adequate reducing/melting equipment to provide metals and metallic alloys.
