摘要： A process for producing pig iron or liquid primary steel products in a smelting unit (1), in particular a melter gasifier. Iron-ore-containing charge materials, and possibly additions, are at least partially reduced in at least one reduction unit (R1, R2, R3, R4) by means of a reducing gas. A first fraction of the at least partially reduced charge materials is melted down in the smelting unit (1), while carbon carriers and oxygen-containing gas are supplied, with the simultaneous formation of the reducing gas. The reducing gas is fed to the reduction unit (R1, R2, R3, R4) and, after the reducing gas has passed through the reduction unit, it is drawn off as top gas. A second fraction of the at least partially reduced charge materials is fed to a smelting reduction unit for reducing and smelting.

摘要： A method is provided for cleaning a gas flow made of top gas and/or off gas and/or export gas from a direct reduction plant or a melt reduction plant, which is loaded with dust and/or fine particulate solids. The gas flow is subjected to a dry cleaning using at least one dry filter, wherein dusts and/or fine particulate raw materials are separated from the gas flow. The cleaned gas flow is fed into a CO2 separating device, wherein CO2 is separated, forming a product gas that is substantially free of water and CO2 and is used for backflushing the dry filter.

摘要： A rolling mill stand for the production of rolled strip or sheet metal includes working rolls which are supported on respective supporting rolls or on intermediate rolls which are supported on supporting rolls. At least one of the rolls having a barrel contour which runs over the entire effective barrel length and can be described by a non-linear function. The barrel contour of this at least one roll having chamfers in at least one of the marginal regions of its longitudinal extent and the chamfers forming a corrected barrel contour in these marginal regions, so that inhomogeneities in the load distribution along the contact line of two adjacent rolls, and in particular in the region of the edges of the strip, are minimized. The corrected barrel contour is obtained by subtracting any non-linear mathematical chamfer function from the contour function described by the non-linear function, so that the pitch of the barrel contour and the pitch of the corrected barrel contour at a transition point from the barrel contour to the corrected barrel contour are identical.

摘要： A system for energy optimization in a plant (3) for producing direct-reduced metal ores (3). The plant (3) has at least one reduction unit (12), a device for separating gas mixtures (7, 7a, 7b) having an associated compressing device (4, 4a, 4b), and a gas-heating device (10) upstream of the reduction unit (12). Part of the process gases (2, 2a, 2b) is fed by a feed line from a smelting reduction plant to the plant for producing direct-reduced metal ores (3). A turbine (8, 8a, 8b) is fit between the device for separating gas mixtures (7, 7a, 7b) and the gas-heating device (10) upstream of the reduction unit (12) such that a pressure drop between the device for separating gas mixtures (7, 7a, 7b) and the reduction unit (12) is converted into forms of energy that can be used to operate additional components (4, 4a, 4b, 15, 15a, 15b) of the plant (3), in particular electrical energy and/or mechanical energy. Energy consumption of the plant (3) is reduced.

摘要： A method and an apparatus for suppression of oscillations in a rolling installation is described. By means of a hydraulic roller engagement third-octave oscillations are effectively suppressed, thus making it possible to improve the quality of the rolled material and/or the productivity of the rolling installation. A manipulated variable is supplied to an electrohydraulic actuating element that acts on at least one hydraulic actuator for the roller engagement and has a rated flow rate of ≧50 l/min. At least a portion of the frequency response at frequencies f≧80 Hz has a magnitude drop of ≦3 dB, and the phase lag φ in this frequency range satisfies the conditions f≧19·{square root over (φ)}+3.1·10−6·φ4 and φ
