摘要： Verfahren zum Betreiben einer Anordnung von einer oder mehreren Düsen (2,3) oder Düsengruppen, wobei jeder Düse (2,3) oder Düsengruppe ein flüssiges Medium über Zuleitungen (5) zugeführt wird, und das flüssige Medium in einen Gasraum (1) zur Kühlung dieses Gases verdüst wird und wobei die Flüssigkeitszuleitung (5a,6) jeder Düse oder Düsengruppe durch ein Absperrventil (7,8) absperrbar ist. Bei Außerbetriebnahme einer Düse (2,3) oder Düsengruppe wird die zwischen Absperrventil (7,8) und Düse (2,3) oder Düsengruppe in der Flüssigkeitszuleitung (5a,6) verbleibende Flüssigkeit entgegen der normalen Strömungsrichtung der Flüssigkeit entfernt
摘要翻译： 当一个喷嘴或喷嘴组不工作时，在流体供应管线中的截止阀和喷嘴或喷嘴组之间残留的流体通过从流体分支出的排水管相对于流体的正常流动方向被去除 在截止阀和喷嘴之间提供管道，并可通过阀门关闭。 可以通过从多路切断阀分支出的排水口去除残留在供给管路中的流体。 这些喷嘴是双体喷嘴，由此除了流体介质之外，气体介质也可以通过供应管线供应到这些喷嘴或喷嘴组中的每一个，并且流体介质由该气体介质蒸发。 气体供应可以通过阀门关闭。

摘要： In a process for descaling a workpiece (22), in particular rolling stock, the workpiece is moved past rotary descaling means, and at least one liquid jet which rotates around an axis of rotation that crosses the surface (23) to be descaled of the workpiece (22) is projected onto the surface (23) to be descaled. In order to cool down the workpiece (22) only to a minor extent and to generate a high spraying pressure with a low working liquid pressure, the liquid jet is intermittently generated, i.e. interrupted at intervals.

摘要： In a process for producing sponge iron from particulate iron oxide-containing material, iron oxide-containing material is reduced to sponge iron with a reducing gas in a reduction zone (4) and gas produced during reduction is withdrawn as top gas. In order to effectively use top gas produced during ore reduction, the CO2 contained in the top gas is removed, the thus obtained CO2-containing waste gas is mixed with an oxygen-containing waste gas is mixed with an oxygen-containing gas, is burned and the thermal energy thus produced is supplied to a consumer.

摘要： In a process for producing sponge iron by direct reduction of iron oxide-containing materials, synthesis gas is mixed with the top gas produced during direct reduction of the iron oxide-containing material and used as CO- and H2-containing reduction gas for the direct reduction and heating of the iron oxide-containing materials up to a reduction temperature. In order to save energy during steel production, in particular during the refining process, one proceeds as follows during direct reduction: a carbon-containing gas, such as natural gas, or a gas with higher hydrocarbons, is used for the direct reduction besides the reduction gas; the iron oxide-containing material is exposed to the reduction gas and to the additionally supplied carbon-containing gas for a period of time longer than that required to finish reduction; and a CO/CO2-ratio from 2 to 5, preferably over 2.5, is set in the reduction gas.

摘要： In a process for producing liquid metal out of charges consisting of ore and additives, the ore is directly reduced to metal sponge in at least one reduction zone (5, 7, 8), the metal sponge is smelted with additives in a smelting gasification zone (11) with the introduction of carbon-containing materials and oxygen-containing gas, and a reduction gas, containing CO and H2, is produced which is used as a process gas to be introduced into the reduction zone (5, 7, 8) where it is converted and subsequently drawn off. Slag-forming additives, particularly calcium carbonate, dolomite, etc., are calcinated using the process gas in a calcinating zone (26') which is separated from the reduction zone (5, 7, 8) and smelting gasification zone (11). To be able to use slag-forming additives aggregate of any grain size without affecting the reduction process, the calcinating zone (26') is connected in parallel, with regard to material flow, to the reduction zone (5, 7, 8), and the calcinated aggregate is introduced directly into the smelting gasifier (10).

摘要： The invention concerns a strip winder comprising at least one pressure roller (2) which can be set against a winder mandrel (1) by means of an adjusting device (6) in order to press strip-form winding material (9) against the winding mandrel (1). To this end, the pressure roller (2) is mounted such that it can rotate on a mounting arm (3) and move relative to the winding mandrel (1) in an approximately radial direction. The mounting arm (3) can be moved towards and pressed against the winding mandrel (1) by means of the adjusting device (6). As the beginning of the strip (14) approaches, the pressure roller (2) can be moved by at least the strip thickness (16) away from the winding mandrel (1) by means of an adjusting device (12) controlled by a control device (15). In order to be able to carry out "step control" easily and with simple means, the pressure roller (2), in known manner, is movable relative to the mounting arm (3) by means of a further adjusting device (12) connected to the control device (15) which causes the pressure roller (2) to move away from the winding mandrel (1) as the beginning of the strip (14) approaches.

摘要： A plant for producing raw iron and/or sponge iron has a direct-reduction shaft furnace (1) for lump iron ore, a melt gasifier (3), a conduit connecting the melt gasifier (3) to the shaft furnace (1) for a reducing gas, a supply conduit (13) connecting the shaft furnace (1) to the melt gasifier (3) for the reduction product in said furnace (1), a top gas line (14) leading out of the shaft furnace (1) with lines (5, 6, 7) opening into the melt gasifier (3) for oxygen-containing gas and carbon vehicles and a run-off (11) on the melt vessel (3) for raw iron and slag. To make it possible to process not only lump but also fine ore economically over a wide range of quantities, the plant has at least one fluidised bed reactor (15, 16) to accept fine ore, a reducing gas inlet (21) thereinto, an exhaust gas outlet (22) from the fluidised bed reactor (15) and an extractor (34) for the reduction product formed in said fluidised bed reactor (15, 16), in which the top gas outlet (14) of the shaft furnace (1) and the exhaust gas outlet (22) of the fluidised bed reactor (15) open into a cleaning device (23) and then into a heater (25, 26) from which leaves the reducing gas inlet line (21) of the fluidised bed reactor (15, 16).

摘要： In a process for producing liquid raw iron (23) or semi-finished steel products from finely divided iron-containing material (15) in a melt gasification region of a melt gasifier (1), the iron-containing material (15) is melted on passing through the bed (26) with the simultaneous formation of a reducing gas in a bed (26) consisting of solid carbon carriers. In order to be able to operate the process with an addition consisting of up to 100 % fine ore, while reliably preventing the separation of the fine ore added, a high temperature burning and/or gasification region (27) is formed in a deoxidising region (III) above the bed (26) by the burning and/or gasification of carbon-containing material (16', 16'') with the direct supply of oxygen, into which the finely divided iron-containing material (15) is fed directly, whereby at least a surface melting of the iron-containing material (15) and its agglomeration are effected by means of the heat released on the reaction of the carbon-containing material (16', 16'').

摘要： Bei einem Verfahren zum Granulieren von Schlämmen (1) soll eine Aufbereitung, d.h. Stückigmachung auch in großen Mengen anfallender Schlämme mit geringem apparativem und energetischem Aufwand ermöglichen, wobei jedoch die hergestellten Granulate hohen Anforderungen an Qualität (Festigkeit, Lagerfähigkeit, Schüttfähigkeit etc.) genügen.
Dies wird dadurch erreicht, indem die Schlämme (1) in einem kontinuierlichen Verfahren verarbeitet werden, u.zw. in einer ersten Prozeßstufe kontinuierlich gemischt (5) und in einer daran anschließenden zweiten Prozeßstufe kontinuierlich granuliert (22) werden.摘要翻译： 污泥的造粒，特别是采矿作业的造粒，是以连续的方法进行的，包括以下两个连续的步骤，其中污泥在第一步中混合并在第二步中造粒。 还要求的是该方法所需的装置。
