    摘要: Das flüssige Metall wird unter dem Einfluß der Schwerkraft aus einem Vorratsbehälter (2) geregelt in eine gekühlte Horizontalstranggießkokille (7) geleitet, darin auf dasselbe eine elektromagenische Kraft in Gießrichtung ausgeübt und der erstarrte Gießstrang kontinuierlich abgezogen. Das flüssige Metall wird aus dem Vorratsbehälter (2) nach unten in die Horizontalstranggießkokille (7) abgelassen und darin in die horizontale Abzugrichtung umgelenkt und zwar so, daß die elektromagnetische Kraft im Sinne einer Zurückhaltung des Gießspiegels in einer entsprechenden oberen Eingießöffnung (6) der Horizontalstranggießkokille (7) unterhalb der eintrittsseitigen Oberkante (10) des anschließenden horizontalen Gießkanals (9) eingestellt wird.

    摘要: In a device for producing sponge iron from lumps of iron oxide in a reduction shaft (1), a hot, dust-containing and carbon monoxide-rich reduction gas is used. The reduction gas is generated in a gas generator by partial oxidation of solid carbon-containing materials and is in part supplied to the reduction shaft through several lateral reduction inlets (3) arranged at the same height around the circumference of the reduction shaft at the lower end of the reduction zone. The lumps of iron oxide are introduced into the reduction shaft through its top area and discharged as sponge iron at its bottom end. Additional reduction gas inlets (15) shaped as downwardly open channels (11) which extend from the outside to the inside of the reduction shaft and/or shaped as ducts which extend obliquely downwards from the outside to the inside of the reduction shaft and have open inner ends are arranged below the plane of the lateral reduction gas inlets. Reduction gas may thus be also supplied to the radial inner area of the reduction shaft, so that the introduction of dust by the reduction gas is not limited to the outer area of the bulk material in the reduction shaft.

    摘要: The invention relates to a device comprising a fusion gasifier (2) and a reduction shaft (1) arranged thereabove and for reduction of iron ore in spongy iron. The spongy iron is introduced through horizontal discharge devices (7) in the lower section of the reduction shaft, and a pipe connection (11) is introduced into the head section of the fusion gasifier where it is melted using a oxygen-containing gas and gasifying means also conveyed into the head of the fusion gasifier, and is reduced to liquid crude iron. A reduction gas is produced at the same time which is conveyed out of the head of the fusion gasifier. The discharge devices lead into a dust-blocking container (5) arranged in a lower section of the reduction shaft and to which the pipe connection leading to the fusion gasifier is attached. The dust-blocking container is connected to a feed device (10) for a seal gas at a higher pressure than the gas pressure in the head of the fusion gasifier thereby preventing gasifying gas from passing into the reduction shaft via the pipe connection. Humidity and volatile constituents have already been removed from the gasifying means before introduction into the fusion gasifier as a result of mixing hot spongy iron with the gasifying means before the introduction thereof into the centre of the gasifier head.

    摘要: In a process for producing liquid pig iron (9) or semifinished steel products from ore reduced into partially and/or totally reduced sponge iron (4) in at least one reduction zone, the sponge iron (4) is molten in a gasification zone (8) of a melting gasifier (1) to which carbon-containing materials (2) and oxygen are supplied, at the same time as a reduction gas is formed. In order to maintain a particular void volume in the bed (13) of solid carbon-containing materials (2) even when finely divided sponge iron (14) is charged, and thus to ensure a good gasification of the bed (13) of solid carbon-containing materials (2), at least the sponge iron (4) is intermittently introduced into the gasification zone (8), forming superimposed layers (14) of sponge iron embedded in the bed (13) of carbon-containing materials (2) and separated by solid carbon-containing materials (2). The sponge iron layers (14) extend over the cross-section of the gasification zone (8), leaving free an area (15) of the cross-section. The reduction gas generated in the gasification zone (8) flows upwards past the sponge iron layers (14), melting the same, through the sections (15) of the cross-section formed by carbon-containing materials (2) and free from sponge iron, gasifying the same.

    摘要: Zur Verwertung von Eisen in oxidischer Form und/oder Eisen in metallischer Form enthaltenden und/oder kohlenstoffhältigen Abfall- oder Reststoffen (38, 25, 34) kommt ein Verfahren zum Einsatz, mit dem flüssiges Roheisen (16) oder Stahlvorprodukte herstellbar sind, wobei Eisenerz (4) in einer Direktreduktionszone (2) zu Eisenschwamm reduziert, der Eisenschwamm in eine Einschmelzvergasungszone (15) unter Zufuhr von kohlenstoffhältigem Material (29) unter Vergasung des kohlenstoffhältigen Materials (29) zu Reduktionsgas eingeschmolzen wird und das Reduktionsgas in die Direktreduktionszone (2) eingeleitet, dort umgesetzt und als Topgas abgezogen wird. Um die Abfall- oder Reststoffe vollständig und energiesparend verwerten zu können, werden die Abfall- oder Reststoffe (38,25,34) nach ihrer chemischen Zusammensetzung in drei Gruppen getrennt gesammelt, u.zw. beinhaltet eine erste Gruppe hauptsächlich Eisen in oxidischer Form enthaltende Stoffe (38), eine zweite Gruppe hauptsächlich Eisen in metallischer Form enthaltende Stoffe (25) und eine dritte Gruppe hauptsächlich kohlenstoffhältige Stoffe (34), und werden die erste Gruppe in die Direktreduktionszone (2) und die zweite Gruppe sowie die dritte Gruppe direkt in die Einschmelzvergasungszone (15) eingesetzt.
