Abstract: A plant complex for pig iron production may include a furnace and a furnace gas conduit system for a furnace gas quantity stream that comprises nitrogen, carbon monoxide, and carbon dioxide. The plant complex may also include a hydrogen source, an H2 gas conduit system for a hydrogen-containing gas quantity stream emitted from the hydrogen source, a mixing apparatus for establishing a mixed gas formed from the furnace gas stream and the hydrogen-containing gas quantity stream. The mixing apparatus may be connected to the furnace gas conduit system and to the H2 gas conduit system. The mixed gas established may have a stoichiometric mixing quotient formed from a dividend with a difference value between molar amounts of hydrogen as minuend and carbon dioxide as subtrahend and of a divisor with a sum value of molar amounts of carbon monoxide and carbon dioxide. The plant complex may also include a mixed gas conduit system and a chemical plant connected to the mixed gas conduit system.

Abstract: The invention relates to a deformation element, in particular for bumper cross member (2) on a motor vehicle, having at least one predetermined breaking point (S) at which, in the event of a crash, the deformation element (1) breaks apart into a breaking segment (1a) facing the crash which is displaced over the course of the crash and into a stationary breaking segment (1b) facing away from the crash. According to the invention the deformation element (1) is produced with at least one material layer (4) made of a fibre-reinforced plastic having a fibre fabric (14) embedded in a bedding material (10), said fibre fabric being exposed, after the deformation element (1) breaks apart, between the breaking segments (1a, 1b) and connecting said breaking segments to each other.

Abstract: A cabinet provided with a cabinet body having at least one vertical row of superimposed compartments which are separated by shelves and which can be opened and closed with compartment doors articulated on the cabinet. This invention simplifies and substantially reduces the cost of parts and of mounting the cabinet. Thus, a joint rod extending over a height of the cabinet body is assigned to each vertical row of compartments. The shelves are guided by a shoulder in the hinge zone having the joint rod and are fixed vertically on the joint rod by flange sleeves overlooking the upper and/or lower side of the shelves and their shoulder. The compartment doors which are adjusted to the heights of the compartments bear, on their rear surface, in the hinge zone, housings for the flange sleeves and can be covered with a shroud.

Abstract: The shut-off system according to the invention for large conduit cross-sections has a swing flap which can be swung to and fro between two end positions about a pivot axis by means of a drive device, wherein the drive device has a drive shaft which is connected to the swing flap via an elbow lever, and at least one lever arm rigidly connected to the drive shaft is provided which is in operative connection with at least one operating cylinder for rotation of the drive shaft. The drive device has a motion link which is fastened so as to be rotatable about a pivot bearing, wherein the operating cylinder is connected to the motion link to pivot the same, and a transmission element is provided between the lever arm and the motion link in order to transmit the pivoting motion of the motion link to the drive shaft.

Abstract: The invention relates to a method for expanding the use of a coiling and uncoiling station (coilbox) located between the roughing train and the finishing train for rolled strip material in hot-rolling mills. The use of said coilbox is expanded by impinging the coil that is to be uncoiled with a pressing force (F) which acts in the direction of the roller table (4) and/or placing the coil in a depression of the roller table in order to process smaller coil weights in a spikeless coilbox, and/or by combining, in a chronological and weight-related manner, the active transfer and passive transfer of a coil from a first coiling station to a second coiling station in order to increase the throughput especially at average coil weights in a spikeless coilbox, and/or by supplying heat to the strip upstream or downstream of the spikeless coilbox and/or thermally insulating the strip or the coilbox in order to variably increase and homogenize the strip temperature.

Abstract: A method and device for measuring and adjusting the evenness and/or tension of a stainless steel strip (1) during cold rolling in a 4-roll stand (2) provided with at least one control loop (4) comprising several actuators (3), resulting in more precise measurement and adjustment due to the fact that an evenness defect (10) is determined by comparing a tension vector (8) with a predefined reference curve (9), whereupon the characteristic of the evenness defect (10) along the width of the strip is broken down into proportional tension vectors (8) in an analysis building block (11) in a mathematically approximated manner and the evenness defect proportions (C1 . . . Cx) determined by real numerical values are supplied to respectively associated control modules (12a; 12b) for actuation of the respective actuator (3).

Abstract: The aim of the invention is to configure a device for winding and unwinding partly rolled products, in a way that ensures the smallest possible accumulation of scrap. To achieve this, a roller (20, 20?, 20?) whose position is controlled and which runs on the periphery of the coil is used during the transfer of the coils from the winding station to the unwinding station. The vertical adjustment of said roller ensures that the coil is completely unwound, even with a diminishing coil diameter.
