摘要： A method of adjusting the composition of a molten metal (2) wherein said molten method (2) is sucked from an initial container (4) into a reactor (5) in which the pressure is lower than that in the initial container (4). The metal (2) is allowed to flow in said reactor (5) in a manner approaching a ram flow, and is processed metallurgically. From the reactor (5), said metal (2) is discharged into a collector container (11), the pressure in the reactor (5) again being lower than that in the collector container. A continuous feed of metal (2) is provided to the initial container and a continuous discharge is effected from the collector container (11). In one embodiment, the molten metal (2) is steel, metallurgical processing involves decarburizing, the denitriding or deoxidation by carbon in a vacuum, and the collector container (11) is a continuous casting distributor. A plant for adjusting the composition of molten metal, using said method, is also disclosed.

摘要： The proposed method is characterized in that the liquid bath is constituted by the melt of a low-carbon steel and molten slag. Oxidation and reducing zones are created through which, along a closed path on the surface of the molten low-carbon steel, is circulated the molten slag, into which are blown powder slag materials which are melted with the heat of a fuel-oxygen torch immersed into the melt. The said method is carried out in a melting reservoir shaped as a closed annular chamber (1) provided with partitions (11) hermetically dividing the gas space above the molten slag into oxidation (6) and reducing (7) zones.

摘要： Un procédé pour la fusion d'un matériau de base contenant du fer dans un réacteur contenant un bain de laitier, comprend la génération de conditions de chauffage et de réduction dans au moins une région réductrice du bain par injection de combustible réducteur et d'un gaz contenant de l'oxygène par au moins une lance immergée par le haut. Le matériau de base est alimenté dans le réacteur en même temps que le réducteur et avec un flux dans ou à côté d'au moins une région réductrice de manière à être soumis à la réduction par fusion, en utilisant du charbon comme réducteur additionnel. Les taux d'injection de l'oxygène et du combustible réducteur sont contrôlés de manière à obtenir les conditions de réduction suffisantes en fournissant le gaz avec un contenu en oxygène d'environ 40 à 100 %, suffisant pour un taux de combustion du combustible réducteur d'environ 40 à 50 %; d'après ce procédé, le CO et l'H2 produits par l'opération de fusion, ainsi que la poussière de carbone sortant du bain avec les gaz de combustion, sont soumis à une combustion postérieure dans le réacteur, permettant un chauffage efficace du bain tout en évitant la ré-oxydation du contenu du bain.

摘要： A two stage reaction for the production of steel from iron carbide is carried out in two separate but interrelated reactors (1, 36). In the first reactor (1), iron carbide, with slag formers, is fed into a feed end (2) and the reaction is well-mixed by the vessel geometry, the stirring action of below-surface injection of oxygen and iron carbide feed, and the evolution of gases from the liquid metal bath (9). The product, containing about 0.5-2 % carbon, is fed into the second reactor (36) where it is refined with subsurface-injected oxygen. The second reaction is autogenous, and the evolved carbon monoxide is fed to the first reactor (1) where it is burned with oxygen in a foamy slag, which, with post-combustion burning in the slag of CO evolved in the first reactor (1), and with iron carbide preheating with the sensible heat of the off-gas from the first reaction, makes that reaction also essentially autogenous.

摘要： A process for smelting iron-containing source material in a reactor containing a slag bath, comprises generating heating and reducing conditions in at least one reducing region of the bath by injection of fuel/reductant and oxygen-containing gas by at least one top submerged lance. The source material is fed to the reactor together with additional reductant and with flux at or adjacent the at least one reducing region so as to be subjected to smelting reduction, using coal as the additional reductant. The rates of injection of oxygen and fuel/reductant are controlled to achieve required, sufficient reducing conditions by providing the injected gas with an oxygen content of from about 40 % to about 100 % sufficient for a degree of combustion of the fuel/reductant of from about 40 % to about 50 %; and wherein CO and H2 generated by the smelting operation, as well as carbon dust carried out of the bath by combustion gases, are subjected to post-combustion in the reactor, enabling efficient heating of the bath whilst preventing re-oxidisation of the bath contents.

摘要： Hot metal is circulated by R-H unit (28) in a closed loop path through first and second hearths (10 and 11) and chambers (12, 14, 16 and 18). Titaniferous material containing iron oxide is introduced into first hearth (10) and the iron oxide therein is reduced in a heating zone in the first hearth (10) to iron to produce titania slag having a reduced iron content which is removed in chamber (12) before the hot metal passes via an underflow weir (22) into chamber (14) at which coal is added and a proportion of the hot metal is removed. The addition of coal is such that more than 2 % by weight of carbon dissolves in the hot metal in the second hearth (11). Coal ash slag is removed at chamber (16), whilst the hot metal containing the dissolved carbon is recirculated to the first hearth (10).
