摘要： In a method and a corresponding device for the active compensation of periodic disturbances of known frequency during hot or cold rolling, such as roll eccentricities, by means of a control system, with the aid of a linear dynamic controller (2) which comprises a model ( P ¯ u ) that describes one part of the dynamic behaviour of the controlled system (1), an output variable ( y ¯ ) is determined from an input variable (u) on the basis of a reference variable (r), and a compensation signal (u LMS ) is generated on the basis of said output variable and a measured output variable (y) of the controlled system (1) and is impressed on the input variable (u) fed to the controlled system (1). As a result, the tracking control is decoupled from the disturbance control, and the controller according to the invention can therefore be inserted into existing control loops for the thickness of the rolling material and/or for the position of the rolls and/or for the rolling force and/or for the roll bending. The compensation signal is generated without prior identification of the eccentricity, which thus permits a more rapid correction of the disturbances.

摘要： According to the inventive method for producing liquid metal (8) comprising at least partly particulate metal supports in a sealing gasifier (2), in which, by feeding either material containing carbon and oxygen or gas containing oxygen, said metal supports are melted in a bed (11) comprised of solid carbon supports, with simultaneous formation of reducing gas, said particulate metal supports are prevented from discharging by being placed into an area exposed to a high temperature maintained by a combustion process, and by being melted at least partly or integrally, while the high temperature combustion area (13) is spatially isolated from the free space (12) of the sealing gasifier (2) situated upstream of the bed and extending into the bed (11), and the flue gas formed in the high temperature combustion area (13) flow out of it while crossed by at least part of the bed(11), is cooled in the bed (11) and removed from the sealing gasifier (2) at the same time as the reducing gas formed in the bed (11).

摘要： Bei einem Verfahren zum Stranggießen von Metallsträngen durch Gießen des Metalles in eine gerade, vertikal ausgerichtete Kokille (9) und nachfolgendes Abziehen des in der Kokille (9) gebildeten geraden Stranges wird der gerade Strang zunächst in einer Biegezone (12) entlang einer Übergangskurve in eine Kreisbogenform gebogen, entlang einer Kreisbogenführung (2) geführt und anschließend in einer End-Richtzone (7) entlang einer Übergangskurve geradegerichtet und danach über eine etwa horizontale Geradführung (8) ausgefördert.
Um ausgehend von einer Stranggießanlage mit einer Bogenkokille (1) eine Anlage mit einer geraden Kokille (9) zu schaffen, wobei möglichst viele Komponenten der Stranggießanlage mit der Bogenkokille (1) weiter Verwendung finden können, wird wie folgt vorgegangen:
Der aus der geraden Kokille (9) austretende gerade Strang wird in mindestens einer Biegezone (12) entlang einer Übergangskurve in eine einen ersten Radius (R min ) aufweisende Kreisbogenform gebogen, in mindestens einer nachgeordneten Richtzone (14) entlang einer Übergangskurve in eine Kreisbogenform mit größerem zweiten Radius (R end ) als der erste Radius (R min ) gebogen, welcher Radius (R end ) vorzugsweise dem der Kreisbogenform einer ursprünglich vorhandenen Stranggießanlage mit Bogenkokille (1) entspricht (Fig.)

摘要： A process is disclosed for treating the scrubbing water from the gas scrubbing process in an iron ore reduction plant. The scrubbing water is brought into direct contact with the gas in two gas scrubbers (1 to 4) arranged in two successive scrubbing stages at the gas-side, is withdrawn from the gas scrubbers and is supplied again to the gas scrubbers after the solids it contains are separated, and after it is treated and cooled. The scrubbing water is separately withdrawn from the two scrubbing stages and only the scrubbing water from the first scrubbing stage is largely freed from solids in a thickener (6), then led into a warm water container (8). The scrubbing water from the second scrubbing stage is directly led into a return water container (10) in which it releases carbon dioxide-rich flash gas led into the scrubbing water in the warm water container to enrich it with carbon dioxide. The scrubbing water from the warm water container is cooled in a heat exchanger (19), then fed back to the gas scrubbers of the two scrubbing stages together with the scrubbing water from the return water container (10). Moreover, part of the carbon dioxide-rich scrubbed gas or part of the carbon dioxide-rich water contained in the return water container may also be led into the warm water container to enrich the scrubbing water in the warm water container with carbon dioxide.

摘要： In a process for the treatment of particulate matter by fluidisation the particulate matter is held and treated in a fluidised bed (2) with the treatment gas flowing from the bottom to the top. To minimise consumption of the treatment gas, and to reduce the entrainment of fines by the treatment gas, particulate matter with a wide ranging grain size distribution and a relative large content of fines is used and the empty pipe flow rate of the treatment gas in the fluidised bed (2) is kept smaller than the flow rate required for the fluidising of the larger particles of the particulate matter.

摘要： The invention relates to a continuous casting machine with an ingot mould (8) which can be inserted into a frame-shaped lifting platform (6), a roller apron (9) adjoining the ingot mould and a mould oscillation facility (3) supporting and moving the lifting platform. A first roller apron segment (12) has been integrated into a downstream roller apron segment (13) in a detachable manner and a die stirrer (20) is supported by a second roller apron segment to keep format change times low by forming a format related machine head.

摘要： The invention concerns a method of producing liquid crude iron or liquid steel fabricated materials from material containing iron oxide. According to this method, fine-particle material which contains iron oxide is reduced by means of a reduction gas in at least one fluid bed reduction stage (7, 8) by the fluid bed process to form fine-particle iron sponge and lumps of ore are reduced in a fixed bed reduction stage (28) to form lumps of iron sponge. The iron sponge is introduced into a fusion gasification zone (11) and melted there by the addition of carbon-carriers and oxygenous gas, a CO and H2-containing reduction gas being produced to reduce the material containing iron oxide. In order to avoid having to treat the fine-particle iron sponge separately from the lumps of iron sponge, the fine-particle iron sponge in the un-processed state and fine-particle form is introduced directly into the fusion gasification zone (11) and melted therein together with the lumps of iron sponge.
